iphone - How to implement a corner page curl UI? -

-

i have app 2 full-screen views, 1 on top of other. show corner of top view curled away, , allow user curl away more until view underneath showing.

the user should able interact whatever part of view underneath exposed, , whatever part of view above exposed.

i'd , feel page turn curling in ibooks. i've done lot of searching ibooks page curl, not turns up. there's great opengl implementation, don't know how there here. ideas?

a simpler implement, , therefore simpler visually approach available here: http://github.com/brow/leaves

you may have bit more success starting small.
