Sometimes willHideViewController from UISplitViewControllerDelegate is not called
I have a problem. My app is a tab bar controller and its first view controller is a split view controller. This seems to be not ok for Apple because documents say a split voew controller must be the root, so perhaps that is the reason of my problems. The problem is that sometimes, willHideViewController from UISplitViewControllerDelegate is not called, so, for this reason, the upper/left button sometimes is not created, which is anoying. I realised, to reproduce this error, try several times this: -Landscape mode. -Select a tab different to split view controller tap. -Move the iPad to portrait
