问题 How this UIPageViewController can be controlled by this header which seems to be UISegmentedControl ? 回答1: The top bar looks like a custom control with an interesting indicator line.

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).

问题 I want to switch between multiple view controllers with a UIPageViewController . These view controllers are static though so i want to design them in my storyboard. Since one can't use relationships or segues to connect them to the UIPageViewController but a datasource, I need to have a datasource object with an IBOutletCollection holding the pages: @property (retain, nonatomic) IBOutletCollection(UIViewController) NSArray* pages; Although, I am not able to connect this outlet to the view
