I am attempting to take a CALayer and put a small page curl at the bottom right. Similar to how the iOS Maps on iPad looks.
I think how they do it is by starting a page curl and stopping it at something like 0.004, so all you see is the corner pulled up. Then when you tap it, it completes the animation sequence.
I am doing this on iOS 5 and can't seem to get this to work and I am not sure if this implementation is acceptable by Apple.
Here is what it looks like:
This is beginning and end position of the animation sequence.
