Assertion failure in UIQueuingScrollView didScrollWithAnimation:force:

Question

I\'ve got a UIPageViewController set up paging my ImageViewController.

The ImageViewController contains a UIScrollView

Answer 1

I have been fighting with this all day. My Conclusions:

If you have a scrollview as the showing ViewController and you are delegate of the scrolls: you're in trouble. Even with the PageViewController configured with Horizontal scrolling, a vertical scrolling on your view will trigger an event. -> this does not cause trouble if: you scroll back to the top of your view before (Not sure how to fix this).

There are good StackOverflow threads like this one.

Basically the solution is:

1 [yourView setViewControllers:yourControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];

2 Use UIPageViewControllerTransitionStylePageCurl as the transition Style.

This fixed most of my problems.

If someone has a solution for the delegation problems with the scrolling, will be most wellcome
