I am creating a custom segue to do custom animation (page curl) when pushing/popping a UINavigationController. The animation works fine except for the fact that it's clipped to the boundaries of the UINavigationController. I've checked all the related views to make sure clipToBounds are set to NO, no luck.
Then I looked at the view hierarchy of UINavigationController itself and found the culprit, a subview of type UINavigationTransitionView. Setting this view's clipToBound to NO does the trick. However, since the view is most likely private and undocumented, it feels hacky/brittle. Is there any other way to accomplish this?
