iOS example using Google's WebP
Using directions created by Carson McDonald, I've created an easy to use UIImage category with a single function for loading a webp image from your app's bundle. It tries to do load an @2x version if the app is running in retina mode.
This example includes a compiled version of Google's webp framework for iOS, and the iOS Simulator. It was built using the directions provided by Carson McDonald here: http://www.ioncannon.net/programming/1483/using-webp-to-reduce-native-ios-app-size
