# Typography Theming

You can theme a navigation bar with your app's typography scheme using the TypographyThemer extension.

You must first add the Typography Themer extension to your project:

```bash
pod 'MaterialComponents/NavigationBar+TypographyThemer'
```

<!--<div class="material-code-render" markdown="1">-->
#### Swift
```swift
// Step 1: Import the TypographyThemer extension
import MaterialComponents.MaterialNavigationBar_TypographyThemer

// Step 2: Create or get a typography scheme
let typographyScheme = MDCTypographyScheme()

// Step 3: Apply the typography scheme to your component
MDCNavigationBarTypographyThemer.applyTypographyScheme(typographyScheme, to: component)
```

#### Objective-C

```objc
// Step 1: Import the TypographyThemer extension
#import "MaterialNavigationBar+TypographyThemer.h"

// Step 2: Create or get a typography scheme
id<MDCTypographyScheming> typographyScheme = [[MDCTypographyScheme alloc] init];

     toNavigationBar:component];
```
