Pinch to reveal animations have showed up in a number of apps.

Krzysztof Zablocki who has created some excellent source code examples including  the previously mentioned NSNotification And KVO Objective-C Categories For Automatic Observer Removal and  SFGestureRecognizers library for easier gesture recognizers in Cocos2D.

Now Krzysztof has created an example showing how to create a pinch to reveal animation using UIKit that was inspired by the Boeing app.

Here’s a video showing the example code in action:

You can read more about the code on Krzysztof’s site here and you can download the code on Github here.

You can find the Boeing app on iTunes here.

A nice interactive effect for showing related image content.
