title: Landscape navigation bar will not resize when locked
body: <p>I have a navigation controller acting as a container view, that is programmatically loaded as the rootViewController in the appDelegate.</p>
  
  <p>In the container class, I lock the orientation of the screen to landscape using this:</p>
  
  <pre><code>- (NSUInteger)supportedInterfaceOrientations {
      return UIInterfaceOrientationMaskLandscape;
  }
  </code></pre>
  
  <p>The app runs in landscape, but the nav bar is still at 44 pixels - the height it should be when in portrait mode. When I flip to the other landscape, it will correctly resize to the smaller 32 pixel version.</p>
  
  <p>I want the app to immediately run with the navbar at the correct 32 pixels. How would I approach this?</p>
