UIPageViewController NSInternalInconsistencyException

Question

I\'m developing a simple UIPageViewController that has two pages. Each page is loaded from a different ViewController with their specific xib

Answer 1

Figured it out (at least what my problem was) - You shouldn't set a UIViewController's self.view directly, but instead use self.view.addSubview(viewA) and then use

UIView.transitionFromView(self.viewA, toView: self.viewB, duration: 0.5, options: UIViewAnimationOptions.TransitionFlipFromLeft, completion: nil)
