RSCubeView lets you apply 3D rotation effect to a UIView.
###Usage
-Add QuartzCore.framework into your XCode project
-Copy RSCubeView.h and RSCubeView.m under the CubeFlip/ folder to your project
-Put #import RSCubeView.h in your source files to start using.
###Example Project
Open CubeFlip.xcodeproj in XCode to immediately see RSCubeView in action.
###Example Code //Perform a 3D rotation on a UIView with a red background to a UIView with a blue background
CGRect rect = CGRectMake(0.f, 0.f, 200.f, 200.f);
RSCubeView* cube = [[RSCubeView alloc] initWithFrame:rect];
[self.view addSubview:cube]; //Add as a subview to your main view
UIView* redView = [[UIView alloc] initWithFrame:rect];
redView.backgroundColor = [UIColor redColor];
UIView* blueView = [[UIView alloc] initWithFrame:rect];
blueView.backgroundColor = [UIColor blueColor];
cube.contentView = redView;
[cube rotateToView:blueView direction:RSCubeViewRotationDirectionDown duration:1.f];
