title: UINavigationController without navigation bar?
body: <p>I have a universal app, and on the iPad version I'm using <code>UISplitViewController</code> to create an interface similar to the Mail app.</p>
  
  <p>I was having trouble pushing new Detail views, so I decided to use a <code>UINavigationController</code> so I could just push and pop views as needed. However, I do not want to use the navigation view or a toolbar. But no matter what I do, I can't hide the navigation bar.</p>
  
  <p>I've tried unchecking "Shows Navigation Bar" in IB, and I've also tried setting:</p>
  
  <pre><code>[self.navigationController setNavigationBarHidden:YES];
  </code></pre>
  
  <p>in the <code>viewDidLoad</code>/<code>viewDidAppear</code>/<code>viewWillAppear</code>. I've also tried it in each of the views that will be pushed. Nothing works.</p>
  
  <p>Is there something I'm missing here? Is it possible to have a <code>UINavigationController</code> without a toolbar or navigation bar?</p>
