I have a UIPageViewController which holds two screens.

self.pageController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStyleScroll navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:nil];

And one of the screen contains tableview on iphone /Collection view on ipad.On some user event we are setting the contentOfset to move the tableview a bit up 

            [table setContentOffset:cell.frame.origin animated:YES];

Then user navigates to next screen using UIPageviewcontroller

Above usecase causes crash on the app with the following logs
