Q:
In the latest PDFNet 6.2 beta library, on iOS 7, we’ve noticed a problem on iOS.
When hiding the status bar using -[UIViewController prefersStatusBarHidden] and using page presentation mode e_trn_single_page, then the viewed page jumps up about 20pt while scrolling and jumps back down 20pt when scrolling ends.
A:
On your view controller, set the property automaticallyAdjustsScrollViewInsets to NO. This should correct the behavior.
