+MDFTextAccessibility assists in selecting text colors that will meet the
+[W3C standards for accessibility](https://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contrast-contrast.html).
+
+[](https://travis-ci.org/material-foundation/material-text-accessibility-ios)
+[](http://codecov.io/github/material-foundation/material-text-accessibility-ios?branch=develop)
+
+*May 24, 2016: We're still staging MDFTextAccessibility, feel free to poke
+around, but non-code things like CocoaPods support and continuous integration
+testing will be ramping up over the next few weeks. The API is relatively stable
+at this point.*
+
+## Accessibility of text
+
+Apps created for the widest range of users should ensure that users can read
+text presented over any background. While the legibility of text depends on many
+things, a great start is to provide a sufficiently large *contrast ratio*
+between foreground text colors and their background colors. The contrast ratio
+of two colors is a measurement of how much the brightness of two colors differ.
+For example, white on dark grey might have a contrast ratio of 9:1, while white
+on medium grey might only have a contrast ratio of 4:1. In general, larger
+contrast ratios are better and will ensure the widest range of users can easily
+read the text in your app.
+
+The [W3C](https://www.w3.org)'s
+[Web Content Accessibility Guidelines](https://www.w3.org/TR/WCAG/#visual-audio-contrast)
+contains two recommendations for text contrast ratios:
+
+1. Minimum contrast: text should have a contrast ratio of at least 4.5:1,
+ except for "large" text, which can have a contrast ratio of 3:1.
+2. Enhanced contrast: text should have a contrast ratio of at least 7:1, except
+ for large text, which can have a contrast ratio of 4.5:1.
+
+"Large" text is nominally defined as at least 18pt in a normal font face or at
+least 14pt in a bold font face. For more information (including some important
+exceptions), see the
+[Guidelines](https://www.w3.org/TR/WCAG/#visual-audio-contrast).
+
+## Computing contrast ratios
+
+Computing acceptable contrast ratios involves the foreground color, the
+background color, the text size, and the transparency of the foreground color,
+if any. MDFTextAccessibility provides convenient access to colors that will
+automatically give acceptable contrast ratios.
+
+For methods that return a UIColor, the color along with its alpha is guaranteed
+to provide a contrast ratio meeting the minimum ratios recommended by the W3C.
+The returned alpha may be greater than the requested alpha to ensure acceptable
+contrast ratios, that is, the returned color may be more opaque than requested
+to ensure that the text remains legible.
+
+## Legible text on images
+
+Displaying text legibly on arbitrary images is difficult because the image
+content can conflict with the text. Images with smooth gradients or blurred
+regions are likely to result in more legible text; images with many details and
+high contrast are less likely to result in legible text.
+
+MDFTextAccessibility provides methods that attempt to select a good color for
+displaying text on a particular image, but the quality of the results will
+depend on the contents of the image. If the content of the image is not known
+(for example, when images provided by the user), then consider using a
+semi-transparent shim between the image and the text to increase contrast.
+
+## Usage
+
+### Basic usage
+
+The simplest usage is to select between black and white text depending on the
+background color, irrespective of the font:
+
+```objective-c
+label.textColor = [MDFTextAccessibility textColorOnBackgroundColor:label.backgroundColor
+ textAlpha:1
+ font:nil];
+```
+
+Many design standards for user interfaces use text colors that are not fully
+opaque. However, transparent text can reduce legibility, so you can request a
+color that is as close as possible to a particular alpha value while still being
+legible:
+
+```objective-c
+label.textColor = [MDFTextAccessibility textColorOnBackgroundColor:label.backgroundColor
+ targetTextAlpha:0.85
+ font:nil];
+```
+
+Since the W3C recommends different contrast ratios for "normal" and "large"
+text, including the font can result in a text color closer to your target alpha
+when appropriate:
+
+```objective-c
+label.textColor = [MDFTextAccessibility textColorOnBackgroundColor:label.backgroundColor
+ textAlpha:0.85
+ font:label.font];
+```
+
+### Advanced usage
+
+For more advanced usage, such as selecting from a set of colors other than white
+and black, see MDFTextAccessibility's
+`textColorFromChoices:onBackgroundColor:options:`.

+
+Material Components for iOS (MDC-iOS) helps developers execute [Material Design](https://www.material.io). Developed by a core team of engineers and UX designers at Google, these components enable a reliable development workflow to build beautiful and functional iOS apps. Learn more about how Material Design supports design and usability best practices across platforms in the [Material Design Platform Adaptation guidelines](https://material.io/guidelines/platforms/platform-adaptation.html).
+
+Material Components for iOS are written in Objective-C and support Swift and Interface Builder.

+
+## Trying out Material Components
+
+Our [catalog](catalog/) showcases Material Components. You can use the `pod try` command from anywhere on your machine to try the components, even if you haven't checked out the repo yet:
+
+~~~ bash
+pod try MaterialComponents
+~~~
+
+In case you have already checked out the repo, run the following command:
+
+~~~ bash
+pod install --project-directory=catalog/
+~~~
+
+If you want to take a look at the implementation of the components, you can find the code inside the `Development Pods` folder.
+Use `cmd-1` to open the project navigator within Xcode. Peal open the `Pods` project and inside the `Development Pods` folder you will find the component source code.
+
+## Installation
+
+### Getting Started with a New Project
+
+Check out our [tutorial](howto/tutorial) for a step-by-step guide to setting up a new project using Material Components.
+
+### Adding Material Components to an Existing Project
+
+[CocoaPods](https://cocoapods.org/) is the easiest way to get started (if you're new to CocoaPods,
+check out their [getting started documentation](https://guides.cocoapods.org/using/getting-started.html).)
+
+To install CocoaPods, run the following commands:
+
+~~~ bash
+sudo gem install cocoapods
+~~~
+
+To integrate Material Components in your existing application, first create a new Podfile:
+
+~~~ bash
+cd your-project-directory
+pod init
+~~~
+
+Next, add the
+[Material Components for iOS pod](https://cocoapods.org/pods/MaterialComponentsIOS)
+to your target in your Podfile:
+
+~~~ ruby
+target "MyApp" do
+ ...
+ pod 'MaterialComponents'
+end
+~~~
+
+If you are using Swift, don’t forget to uncomment the `use_frameworks!` line
+at the top of your Podfile.
+
+Then run the command:
+
+~~~ bash
+pod install
+~~~
+
+Now you're ready to get started in Xcode. Don't forget to open the workspace Cocoapods created for you instead of the original project:
+
+~~~ bash
+open your-project.xcworkspace
+~~~
+
+### Usage
+
+The components are built upon familiar UIKit classes and can be added to a view with just a couple of lines. Simply import the Material Components header for the component you're interested in, and add it to your view.
+
+#### Swift
+
+~~~ swift
+import MaterialComponents.MaterialButtons
+
+class ViewController: UIViewController {
+
+ override func viewDidLoad() {
+ super.viewDidLoad()
+ let raiseButton = MDCRaisedButton.init();
+ raiseButton.setTitle("Raised Button", forState: .Normal);
+ raiseButton.sizeToFit();
+ raiseButton.addTarget(self, action: #selector(tapped), forControlEvents: .TouchUpInside);
+ self.view.addSubview(raiseButton);
+ }
+
+ func tapped(sender: UIButton!){
+ NSLog("Button was tapped!");
+ }
+
+}
+~~~
+
+#### Objective-C
+
+~~~ objc
+#import "MaterialButtons.h"
+
+@implementation ViewController
+
+- (void)viewDidLoad {
+ [super viewDidLoad];
+
+ MDCRaisedButton *raisedButton = [MDCRaisedButton new];
+ [raisedButton setTitle:@"Raised Button" forState:UIControlStateNormal];
+ [raisedButton sizeToFit];
+ [raisedButton addTarget:self
+ action:@selector(tapped:)
+ forControlEvents:UIControlEventTouchUpInside];
+
+ [self.view addSubview:raisedButton];
+}
+
+- (void)tapped:(id)sender {
+ NSLog(@"Button was tapped!");
+}
+
+@end

+/**
+ The MDCAppBarContainerViewController controller provides an interface for placing a
+ UIViewController behind an App Bar.
+
+ The MDCAppBarContainerViewController class is commonly referred to as the "wrapper API" for the
+ Material App Bar. This contrasts with the "injection" APIs as represented by the APIs in
+ MDCAppBar.h.
+
+ Use the MDCAppBarContainerViewController class when you do not own and cannot alter a view
+ controller to which you want to add an App Bar. If you do own and can modify a view controller
+ it is recommended that you use the MDCAppBar.h APIs instead.
+
+ ### Why we recommend using the MDCAppBar.h APIs over this one
+
+ Wrapping a view controller affects your app code in a variety of not-so-nice ways.
+
+ 1. Wrapped view controllers often need to be unwrapped in a variety of settings.
+ 2. The wrapped view controller's parentViewController is now a level of indirection from its
+ previous parent.
+ 3. Wrapping a view controller can affect things like "isMovingToParentViewController" in
+ wonderfully subtle ways.

+ The string values of the names of the tints and accents are required in two places:
+ - in the definitions of the API names (such as MDCPaletteTint500Name)
+ - in the private implementation, for example, to check incoming strings are correct.
+
+ We can't have both the public and the private implementations depending on each other, since that
+ would cause a dependency loop. The normal solution to a dependency loop is to factor out the
+ common part into a new "unit" and have both of the original implementations depend on this new
+ unit. In this case, the string values would get factored out into the new unit.
+
+ However, the code in question is initializing constant data (the strings), the definitions must use
+ compile-time constants. For example, if we factored out the string values as "internal" names, the
+ following would still not work because the initialization doesn't use compile-time constants.
+
+ ```objective-c
+ static const NSString *MDCPaletteTint500Name = MDCPaletteTint500InternalName;
+ ```
+
+ To get around this, we instead drop down a level and define the strings in the preprocessor, so
+ that the compiler still sees compile-time constants. This has the downside of possibly duplicating
+ strings if the compiler can't optimize string storage across compilation units.

+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the
+ Work (including but not limited to damages for loss of goodwill,

+ communication on electronic mailing lists, source code control systems,
+ and issue tracking systems that are managed by, or on behalf of, the
+ Licensor for the purpose of discussing and improving the Work, but

+ designated in writing by the copyright owner as "Not a Contribution."
+
+ "Contributor" shall mean Licensor and any individual or Legal Entity
+ on behalf of whom a Contribution has been received by Licensor and
+ subsequently incorporated within the Work.
+
+ 2. Grant of Copyright License. Subject to the terms and conditions of
+ this License, each Contributor hereby grants to You a perpetual,
+ worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+ copyright license to reproduce, prepare Derivative Works of,

+
+ 3. Grant of Patent License. Subject to the terms and conditions of

+ where such license applies only to those patent claims licensable
+ by such Contributor that are necessarily infringed by their
+ Contribution(s) alone or by combination of their Contribution(s)
+ with the Work to which such Contribution(s) was submitted. If You
+ institute patent litigation against any entity (including a
+ cross-claim or counterclaim in a lawsuit) alleging that the Work
+ or a Contribution incorporated within the Work constitutes direct
+ or contributory patent infringement, then any patent licenses
+ granted to You under this License for that Work shall terminate
+ as of the date such litigation is filed.
+
+ 4. Redistribution. You may reproduce and distribute copies of the
+ Work or Derivative Works thereof in any medium, with or without
+ modifications, and in Source or Object form, provided that You
+ meet the following conditions:
+
+ (a) You must give any other recipients of the Work or
+ Derivative Works a copy of this License; and
+
+ (b) You must cause any modified files to carry prominent notices
+ stating that You changed the files; and
+
+ (c) You must retain, in the Source form of any Derivative Works
+ that You distribute, all copyright, patent, trademark, and
+ attribution notices from the Source form of the Work,
+ excluding those notices that do not pertain to any part of
+ the Derivative Works; and
+
+ (d) If the Work includes a "NOTICE" text file as part of its
+ distribution, then any Derivative Works that You distribute must
+ include a readable copy of the attribution notices contained
+ within such NOTICE file, excluding those notices that do not
+ pertain to any part of the Derivative Works, in at least one
+ of the following places: within a NOTICE text file distributed
+ as part of the Derivative Works; within the Source form or
+ documentation, if provided along with the Derivative Works; or,
+ within a display generated by the Derivative Works, if and
+ wherever such third-party notices normally appear. The contents
+ of the NOTICE file are for informational purposes only and
+ do not modify the License. You may add Your own attribution
+ notices within Derivative Works that You distribute, alongside
+ or as an addendum to the NOTICE text from the Work, provided
+ that such additional attribution notices cannot be construed
+ as modifying the License.
+
+ You may add Your own copyright statement to Your modifications and
+ may provide additional or different license terms and conditions
+ for use, reproduction, or distribution of Your modifications, or
+ for any such Derivative Works as a whole, provided Your use,
+ reproduction, and distribution of the Work otherwise complies with
+ the conditions stated in this License.
+
+ 5. Submission of Contributions. Unless You explicitly state otherwise,
+ any Contribution intentionally submitted for inclusion in the Work
+ by You to the Licensor shall be under the terms and conditions of
+ this License, without any additional terms or conditions.
+ Notwithstanding the above, nothing herein shall supersede or modify
+ the terms of any separate license agreement you may have executed
+ with Licensor regarding such Contributions.
+
+ 6. Trademarks. This License does not grant permission to use the trade
+ names, trademarks, service marks, or product names of the Licensor,
+ except as required for reasonable and customary use in describing the
+ origin of the Work and reproducing the content of the NOTICE file.
+
+ 7. Disclaimer of Warranty. Unless required by applicable law or
+ agreed to in writing, Licensor provides the Work (and each
+ Contributor provides its Contributions) on an "AS IS" BASIS,
+ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+ implied, including, without limitation, any warranties or conditions
+ of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+ PARTICULAR PURPOSE. You are solely responsible for determining the
+ appropriateness of using or redistributing the Work and assume any
+ risks associated with Your exercise of permissions under this License.
+
+ 8. Limitation of Liability. In no event and under no legal theory,
+ whether in tort (including negligence), contract, or otherwise,
+ unless required by applicable law (such as deliberate and grossly
+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the
+ Work (including but not limited to damages for loss of goodwill,
+ work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses), even if such Contributor
+ has been advised of the possibility of such damages.
+
+ 9. Accepting Warranty or Additional Liability. While redistributing
+ the Work or Derivative Works thereof, You may choose to offer,
+ and charge a fee for, acceptance of support, warranty, indemnity,
+ or other liability obligations and/or rights consistent with this
+ License. However, in accepting such obligations, You may act only
+ on Your own behalf and on Your sole responsibility, not on behalf
+ of any other Contributor, and only if You agree to indemnify,
+ defend, and hold each Contributor harmless for any liability
+ incurred by, or claims asserted against, such Contributor by reason
+ of your accepting any such warranty or additional liability.

+MDFTextAccessibility assists in selecting text colors that will meet the
+[W3C standards for accessibility](https://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contrast-contrast.html).
+
+[](https://travis-ci.org/material-foundation/material-text-accessibility-ios)
+[](http://codecov.io/github/material-foundation/material-text-accessibility-ios?branch=develop)
+
+*May 24, 2016: We're still staging MDFTextAccessibility, feel free to poke
+around, but non-code things like CocoaPods support and continuous integration
+testing will be ramping up over the next few weeks. The API is relatively stable
+at this point.*
+
+## Accessibility of text
+
+Apps created for the widest range of users should ensure that users can read
+text presented over any background. While the legibility of text depends on many
+things, a great start is to provide a sufficiently large *contrast ratio*
+between foreground text colors and their background colors. The contrast ratio
+of two colors is a measurement of how much the brightness of two colors differ.
+For example, white on dark grey might have a contrast ratio of 9:1, while white
+on medium grey might only have a contrast ratio of 4:1. In general, larger
+contrast ratios are better and will ensure the widest range of users can easily
+read the text in your app.
+
+The [W3C](https://www.w3.org)'s
+[Web Content Accessibility Guidelines](https://www.w3.org/TR/WCAG/#visual-audio-contrast)
+contains two recommendations for text contrast ratios:
+
+1. Minimum contrast: text should have a contrast ratio of at least 4.5:1,
+ except for "large" text, which can have a contrast ratio of 3:1.
+2. Enhanced contrast: text should have a contrast ratio of at least 7:1, except
+ for large text, which can have a contrast ratio of 4.5:1.
+
+"Large" text is nominally defined as at least 18pt in a normal font face or at
+least 14pt in a bold font face. For more information (including some important
+exceptions), see the
+[Guidelines](https://www.w3.org/TR/WCAG/#visual-audio-contrast).
+
+## Computing contrast ratios
+
+Computing acceptable contrast ratios involves the foreground color, the
+background color, the text size, and the transparency of the foreground color,
+if any. MDFTextAccessibility provides convenient access to colors that will
+automatically give acceptable contrast ratios.
+
+For methods that return a UIColor, the color along with its alpha is guaranteed
+to provide a contrast ratio meeting the minimum ratios recommended by the W3C.
+The returned alpha may be greater than the requested alpha to ensure acceptable
+contrast ratios, that is, the returned color may be more opaque than requested
+to ensure that the text remains legible.
+
+## Legible text on images
+
+Displaying text legibly on arbitrary images is difficult because the image
+content can conflict with the text. Images with smooth gradients or blurred
+regions are likely to result in more legible text; images with many details and
+high contrast are less likely to result in legible text.
+
+MDFTextAccessibility provides methods that attempt to select a good color for
+displaying text on a particular image, but the quality of the results will
+depend on the contents of the image. If the content of the image is not known
+(for example, when images provided by the user), then consider using a
+semi-transparent shim between the image and the text to increase contrast.
+
+## Usage
+
+### Basic usage
+
+The simplest usage is to select between black and white text depending on the
+background color, irrespective of the font:
+
+```objective-c
+label.textColor = [MDFTextAccessibility textColorOnBackgroundColor:label.backgroundColor
+ textAlpha:1
+ font:nil];
+```
+
+Many design standards for user interfaces use text colors that are not fully
+opaque. However, transparent text can reduce legibility, so you can request a
+color that is as close as possible to a particular alpha value while still being
+legible:
+
+```objective-c
+label.textColor = [MDFTextAccessibility textColorOnBackgroundColor:label.backgroundColor
+ targetTextAlpha:0.85
+ font:nil];
+```
+
+Since the W3C recommends different contrast ratios for "normal" and "large"
+text, including the font can result in a text color closer to your target alpha
+when appropriate:
+
+```objective-c
+label.textColor = [MDFTextAccessibility textColorOnBackgroundColor:label.backgroundColor
+ textAlpha:0.85
+ font:label.font];
+```
+
+### Advanced usage
+
+For more advanced usage, such as selecting from a set of colors other than white
+and black, see MDFTextAccessibility's
+`textColorFromChoices:onBackgroundColor:options:`.

+
+Material Components for iOS (MDC-iOS) helps developers execute [Material Design](https://www.material.io). Developed by a core team of engineers and UX designers at Google, these components enable a reliable development workflow to build beautiful and functional iOS apps. Learn more about how Material Design supports design and usability best practices across platforms in the [Material Design Platform Adaptation guidelines](https://material.io/guidelines/platforms/platform-adaptation.html).
+
+Material Components for iOS are written in Objective-C and support Swift and Interface Builder.

+
+## Trying out Material Components
+
+Our [catalog](catalog/) showcases Material Components. You can use the `pod try` command from anywhere on your machine to try the components, even if you haven't checked out the repo yet:
+
+~~~ bash
+pod try MaterialComponents
+~~~
+
+In case you have already checked out the repo, run the following command:
+
+~~~ bash
+pod install --project-directory=catalog/
+~~~
+
+If you want to take a look at the implementation of the components, you can find the code inside the `Development Pods` folder.
+Use `cmd-1` to open the project navigator within Xcode. Peal open the `Pods` project and inside the `Development Pods` folder you will find the component source code.
+
+## Installation
+
+### Getting Started with a New Project
+
+Check out our [tutorial](howto/tutorial) for a step-by-step guide to setting up a new project using Material Components.
+
+### Adding Material Components to an Existing Project
+
+[CocoaPods](https://cocoapods.org/) is the easiest way to get started (if you're new to CocoaPods,
+check out their [getting started documentation](https://guides.cocoapods.org/using/getting-started.html).)
+
+To install CocoaPods, run the following commands:
+
+~~~ bash
+sudo gem install cocoapods
+~~~
+
+To integrate Material Components in your existing application, first create a new Podfile:
+
+~~~ bash
+cd your-project-directory
+pod init
+~~~
+
+Next, add the
+[Material Components for iOS pod](https://cocoapods.org/pods/MaterialComponentsIOS)
+to your target in your Podfile:
+
+~~~ ruby
+target "MyApp" do
+ ...
+ pod 'MaterialComponents'
+end
+~~~
+
+If you are using Swift, don’t forget to uncomment the `use_frameworks!` line
+at the top of your Podfile.
+
+Then run the command:
+
+~~~ bash
+pod install
+~~~
+
+Now you're ready to get started in Xcode. Don't forget to open the workspace Cocoapods created for you instead of the original project:
+
+~~~ bash
+open your-project.xcworkspace
+~~~
+
+### Usage
+
+The components are built upon familiar UIKit classes and can be added to a view with just a couple of lines. Simply import the Material Components header for the component you're interested in, and add it to your view.
+
+#### Swift
+
+~~~ swift
+import MaterialComponents.MaterialButtons
+
+class ViewController: UIViewController {
+
+ override func viewDidLoad() {
+ super.viewDidLoad()
+ let raiseButton = MDCRaisedButton.init();
+ raiseButton.setTitle("Raised Button", forState: .Normal);
+ raiseButton.sizeToFit();
+ raiseButton.addTarget(self, action: #selector(tapped), forControlEvents: .TouchUpInside);
+ self.view.addSubview(raiseButton);
+ }
+
+ func tapped(sender: UIButton!){
+ NSLog("Button was tapped!");
+ }
+
+}
+~~~
+
+#### Objective-C
+
+~~~ objc
+#import "MaterialButtons.h"
+
+@implementation ViewController
+
+- (void)viewDidLoad {
+ [super viewDidLoad];
+
+ MDCRaisedButton *raisedButton = [MDCRaisedButton new];
+ [raisedButton setTitle:@"Raised Button" forState:UIControlStateNormal];
+ [raisedButton sizeToFit];
+ [raisedButton addTarget:self
+ action:@selector(tapped:)
+ forControlEvents:UIControlEventTouchUpInside];
+
+ [self.view addSubview:raisedButton];
+}
+
+- (void)tapped:(id)sender {
+ NSLog(@"Button was tapped!");
+}
+
+@end

+/**
+ The MDCAppBarContainerViewController controller provides an interface for placing a
+ UIViewController behind an App Bar.
+
+ The MDCAppBarContainerViewController class is commonly referred to as the "wrapper API" for the
+ Material App Bar. This contrasts with the "injection" APIs as represented by the APIs in
+ MDCAppBar.h.
+
+ Use the MDCAppBarContainerViewController class when you do not own and cannot alter a view
+ controller to which you want to add an App Bar. If you do own and can modify a view controller
+ it is recommended that you use the MDCAppBar.h APIs instead.
+
+ ### Why we recommend using the MDCAppBar.h APIs over this one
+
+ Wrapping a view controller affects your app code in a variety of not-so-nice ways.
+
+ 1. Wrapped view controllers often need to be unwrapped in a variety of settings.
+ 2. The wrapped view controller's parentViewController is now a level of indirection from its
+ previous parent.
+ 3. Wrapping a view controller can affect things like "isMovingToParentViewController" in
+ wonderfully subtle ways.

+ 3. On touch up, the ink ripple will lose energy, opacity will start to decrease.

+ The string values of the names of the tints and accents are required in two places:
+ - in the definitions of the API names (such as MDCPaletteTint500Name)
+ - in the private implementation, for example, to check incoming strings are correct.
+
+ We can't have both the public and the private implementations depending on each other, since that
+ would cause a dependency loop. The normal solution to a dependency loop is to factor out the
+ common part into a new "unit" and have both of the original implementations depend on this new
+ unit. In this case, the string values would get factored out into the new unit.
+
+ However, the code in question is initializing constant data (the strings), the definitions must use
+ compile-time constants. For example, if we factored out the string values as "internal" names, the
+ following would still not work because the initialization doesn't use compile-time constants.
+
+ ```objective-c
+ static const NSString *MDCPaletteTint500Name = MDCPaletteTint500InternalName;
+ ```
+
+ To get around this, we instead drop down a level and define the strings in the preprocessor, so
+ that the compiler still sees compile-time constants. This has the downside of possibly duplicating
+ strings if the compiler can't optimize string storage across compilation units.

+ We implement our own touch handling here instead of using gesture recognizers. This allows more
+ fine grained control over how the thumb track behaves, including more specific logic over what
+ counts as a tap vs. a drag.
+
+ Note that we must use -touchesBegan:, -touchesMoves:, etc here, rather than the UIControl methods
+ -beginDraggingWithTouch:withEvent:, -continueDraggingWithTouch:withEvent:, etc. This is because
+ with those events, we are forced to disable user interaction on our subviews else the events could
+ be swallowed up by their event handlers and not ours. We can't do this because the we have an ink
+ controller attached to the thumb view, and that needs to receive touch events in order to know when
+ to display ink.
+
+ Using -touchesBegan:, etc. solves this problem because we can handle touches ourselves as well as
+ continue to have them pass through to the contained thumb view. So we get our custom event handling
+ without disabling the ink display, hurray!
+
+ Because we set `multipleTouchEnabled = NO`, the sets of touches in these methods will always be of
+ size 1. For this reason, we can simply call `-anyObject` on the set instead of iterating through
+ every touch.

+
+ You may add Your own copyright statement to Your modifications and

+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the
+ Work (including but not limited to damages for loss of goodwill,
+ work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses), even if such Contributor
+ has been advised of the possibility of such damages.

+ or contributory patent infringement, then any patent licenses
+ granted to You under this License for that Work shall terminate

+ as part of the Derivative Works; within the Source form or
+ documentation, if provided along with the Derivative Works; or,
+ within a display generated by the Derivative Works, if and

+ do not modify the License. You may add Your own attribution
+ notices within Derivative Works that You distribute, alongside
+ or as an addendum to the NOTICE text from the Work, provided
+ that such additional attribution notices cannot be construed
+ as modifying the License.
+
+ You may add Your own copyright statement to Your modifications and
+ may provide additional or different license terms and conditions
+ for use, reproduction, or distribution of Your modifications, or

+ To install CocoaPods, run the following commands:
+
+ ``` bash
+ sudo gem install cocoapods
+ ```
+
+
+2. {: .step-list-item } ### Create Podfile
+
+ Once you've created an iOS application in Xcode you can start using
+ Material Components for iOS.
+
+ To initialize CocoaPods in your project, run the following commands:
+
+ ``` bash
+ cd your-project-directory
+ pod init
+ ```
+
+3. {: .step-list-item } ### Edit Podfile
+
+ Once you've initialized CocoaPods, add the
+ [Material Components for iOS Pod](https://cocoapods.org/pods/MaterialComponentsIOS)
+ to your target in your Podfile:
+
+
+ ``` ruby
+ target "MyApp" do
+ ...
+ pod 'MaterialComponents'
+ end
+ ```
+
+ If you are using Swift, don’t forget to uncomment the `use_frameworks!` line
+ at the top of your Podfile.
+
+ Then run the command:
+
+ ``` bash
+ pod install
+ open your-project.xcworkspace
+ ```
+
+ Now you're ready to get started in Xcode.
+
+4. {: .step-list-item } ### Usage
+
+ Now you’re ready to add a component (e.g. Buttons) to your app!
+ Include the Material Components header for the component you're interested
+ in to your app (detailed below) to get all of the required classes.
+
+ Choose from Objective-C or Swift:
+
+ <!--<div class="material-code-render" markdown="1">-->
+ #### Objective-C
+
+ ``` objc
+ #import "MaterialButtons.h"
+
+ @implementation ViewController
+
+ - (void)viewDidLoad {
+ [super viewDidLoad];
+
+ MDCRaisedButton *raisedButton = [MDCRaisedButton new];
+ [raisedButton setTitle:@"Raised Button" forState:UIControlStateNormal];
+ [raisedButton sizeToFit];
+ [raisedButton addTarget:self
+ action:@selector(tapped:)
+ forControlEvents:UIControlEventTouchUpInside];
+
+ [self.view addSubview:raisedButton];
+ }
+
+ - (void)tapped:(id)sender {
+ NSLog(@"Button was tapped!");
+ }
+
+ @end
+ ```
+
+ #### Swift
+
+ ``` swift
+ import MaterialComponents.MaterialButtons
+
+ class MDCBuildTestViewController: UIViewController {
+
+ override func viewDidLoad() {
+ super.viewDidLoad()
+ let raiseButton = MDCRaisedButton.init();
+ raiseButton.setTitle("Raised Button", forState: .Normal);
+ raiseButton.sizeToFit();
+ raiseButton.addTarget(self, action: "tapped:", forControlEvents: .TouchUpInside);
+ self.view.addSubview(raiseButton);
+ }
+
+ func tapped(sender: UIButton!){
+ NSLog("Button was tapped!");
+ }
+
+ }
+ ```
