title: shouldAutorotateToInterfaceOrientation not called for all expected orientation modes
body: <p>I have a UIViewController added to a window and my app is configured to support Portrait and LandscapeLeft orientations in the Info.plist file.</p>
  
  <p>I'm holding the device in Landscape Left and after my view loads, I see two calls to '<code>shouldAutorotateToInterfaceOrientation</code>'. However, both times the method is called, the value of '<code>toInterfaceOrientation</code>' is always '<code>UIInterfaceOrientationPortrait</code>'.</p>
  
  <p>I was expecting one call to Portrait and at least another for '<code>UIInterfaceOrientationLandscapeLeft</code>' since that is how I'm currently holding the device.</p>
  
  <p>The Controller's view xib is configured to with Portrait mode to load the view but I thought I'd be asked on what orientations are supported besides Portrait.</p>
  
  <p>Any ideas why I don't get two different orientation modes passed into '<code>shouldAutorotateToInterfaceOrientation</code>'?</p>
