title: Titles not appearing on the ViewControllers navigation bar
body: <p>I am currently using the storyboard interface builder to design my GUI.</p>
  
  <p>My structure looks like following in storyboard</p>
  
  <pre><code>-&gt; Navigation Controller -&gt; Tab Bar Controller -&gt; SomeViewController
                                                 -&gt; AnotherViewController
  </code></pre>
  
  <p>Navigation Bar and Tab Bar appears fine in the ViewControllers, and the titles are set and visible in the editor, but in simulation the titles <em>disappear</em>.</p>
  
  <p>How do i resolve this problem?</p>
  
  <p>FYI: <code>Navigation Controller</code> and <code>Tab Bar Controller</code> are not bound to any Custom Class.</p>
