Some time ago I mentioned a library providing an add-on category allowing you to recreate the Mac OS X genie effect on UIViews called BCGenieEffect from Bartosz Ciechanowski.
Here is a library from Bartosz based inspired by the private meshTransform property and CAMeshTransform for applying mesh transforms to a view hierarchy called BCMeshTransformView.
With BCMeshTransform you can create simple transforms, animated mesh transforms, apply directional lighting and more. A demo project is included.
Here is a set of images showing zoom, curtain, and jelly effects created using BCMeshTransformView taken from the included demo project:
You can find BCMeshTransformView on Github here.
You can read more about mesh tranforms with Core Animation and the creation of BCMeshTransformView in an in-depth writeup over on Bartosz’s blog.
A nice library for creating some great visual effects to UIKit elements.
