问题
I would like to 'bend' a view exactly like Flipboard app. I succeeded to flip an entire view, but not to bend it. My strategy is this: make a view/layer from half of the view I want to bend, add this to the view and flip this new view. So: how do I draw in a view/layer just half of another view?

Hey I recently used this code which works fine for me !!! You can get a flipboard like page animation with fold from center. It's concept is simple and it's easy to use. Just one class i.e .h .m file need to add in your project "AFKPageFliper".

Hope this help for you too !!
