#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.
ARC is not enabled for the project, but you can easily convert it to arc with the XCode built in ARC converter or by remove the dealloc method and the two or three release calls.
If you are too lazy for that, you can still set the -fno-objc-arc compiler flag.

##Video: Here are two examples of the use of A3ParallaxScrollView.
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 in the repository.

##Usage: Add the A3ParallaxScrollView directory to your project.
Initialize a A3ParallaxScrollView like any other View by code or in the InterfaceBuilder. Now you can add any views to it with a specified acceleration:

- (void)addSubview:(UIView *)view withAcceleration:(CGPoint) acceleration

or you can simply add a subview to your A3ParallaxScrollView and set his acceleration afterwards with acceleration setter.

- (void)setAcceleration:(CGPoint) acceleration forView:(UIView *)view
