title: How to disable portrait orientation on UINavigationController rootViewController
body: <p>I have a class, HomeView, as the rootViewController of a UINavigationController on my iPad application. Only landscape orientation is set in the info.plist file and HomeView does not implement <code>shouldRotateToInterfaceOrientation:</code>, however the view is rotating for both orientations while the simulator is rotating.</p>
  
  <p>How do I only use the landscape orientations in my UIViewController?</p>
