A UIScrollView subclass with multiple layers and a parallax effect.
To use just add SWParallaxScrollView.h and SWParallaxScrollView.mm to your project or install via CocoaPods.
Add a pod entry to your Podfile:
pod 'SWParallaxScrollView', '~> 0.1.1'
Install the pod(s) by running:
Instantiate and configure SWParallaxScrollView like a regular UIScrollView. When adding subviews they get added on layer 0 by default and everything behaves like a regular scroll view. Subviews can also be added to a given layer:
[parallaxScrollView addSubview: someView onLayer: layer]
If the layer is less than zero those subviews will scroll slower than the regular scroll view. And if the layer is greater than 0 the subviews will scroll faster.
To run the demo open ParallaxScrollView.xcodeproj and run.
