title: setStatusBarHidden:NO after XIB load covers UINavigationBar
body: <p>When <code>setStatusBarHidden:NO</code> is set <strong><em>before</em></strong> the view loads, the <code>UINavigationBar</code> and other elements appear aligned immediately below the StatusBar as they should. However, when <code>setStatusBarHidden:NO</code> is set <strong><em>after</em></strong> the view loads, the <code>UINavigationBar</code> is partially covered.</p>
  
  <p>The StatusBar must be revealed after loading the said view, but how can this be done without encountering the aforementioned problem?</p>
