Partial page curl by pan gesture like in UIPageViewController

问题

I would like to partly display a view controller exactly like

UIModalTransitionStylePartialCurl

, but instead of the curling animation i want to curl the view by a pan gesture

My goal is to get the same affect like when using UIPageViewController to switch between ViewControllers by dragging\curling the page according to the user touches (not a swipe gesture).

Any help will be appreciated.
