I have a UISplitViewController that shows the MasterViewController only when in landscape, the default.
If I start in portrait, click a button to play a video (primary function of my app), then go to full screen, then rotate into landscape, then exit full screen: the MasterViewController is not displayed.
Instead, where the master should be, it is simply black dead space. On the right side, the detail view controller is displayed correctly.
I cannot figure out why the master is not being displayed. This is with iOS 6.
