title: UIView not resizing correctly with UINavigationController in iOS 7
body: <p>I encountered a strange behaviour of a view in an iOS 6.1 app which I tried ran with the iOS 7 beta 2 and on my iPhone.
  This app has a UINaviagationController which works fine if I run it in the iOS 6.1 simulator. However, with the Xcode DP the bottom part of the view is cut off. See picture.

  <p>Does anyone know how to fix this? I am drawing the box that you see as cut off on the bottom (self.frame.size.height) of the UIView which is managed by the navigation controller.</p>
  
  <p>Thanks.</p>
