What is A3ParallaxScrollView?

A3ParallaxScrollView is a UIScrollView subclass with a parallax scrolling effect on iPhone and iPad.

It is written in Objective-C and works for all iOS applications using ARC.

The first is a little Demo with a lot of views and additional custom transformations (sine movement of the moon).
The other one shows a Path like scrolling behaviour.

Both sample projects are included in the github repository.
