Parallax UIView category which can be used in iOS prior to 7 (tested with iOS 6.1)
It's as simple as setting UIView's (or it's any subclass) param iOS6ParallaxIntensity value to any other than 0.
self.label = [[UILabel alloc] init]; ... self.label.iOS6ParallaxIntensity = 15;
To use this you need to include CoreMotion.framework to your project.
This currently works only with ARC!
