Map Curl Effect [duplicate]

Question

I want to make map curl effect just like iPhone 5 map. And many apps on App store have already this feature but I can't find any good source to implement it. Please help me. It should start with curled corner that when touching it expand to half of the screen. Curled corner is not image.

Just look at this reference. https://www.dropbox.com/sh/d51z86xtb93exc2/yRnbgpz6cc

Thanks in advance.
