GTM HTTP Fetcher makes it easy for Cocoa applications to perform http operations. The fetcher is implemented as a wrapper on NSURLConnection, so its behavior is asynchronous and uses operating-system settings on iOS and Mac OS X.
NOTE: Because NSURLConnection is deprecated as of iOS 9 and OS X 10.11, this class has been superseded by GTMSessionFetcher.
To get started with GTM HTTP Fetcher and the Objective-C Client Library, read the wiki.
