title: how to change title of ... more navigation
body: <p>I have an interface laid out in storyboard, and one of my controllers gets pushed into the ... <strong>More... section of the tab bar controller</strong>. I cannot seem to find a way to set it's navigation item's title. It is set up in the storyboard, but does not appear.</p>
  
  <p>Here's the structure Tabbar > relationship to Navigation controller> relationship to view controller</p>
  
  <pre><code>self.navigationItem.title = @"DOES NOT WORK";
  
      UINavigationBar *moreNavigationBar = self.tabBarController.moreNavigationController. navigationBar;
      moreNavigationBar.topItem.title = @"SETS THE BACK BUTTON TITLE";
  </code></pre>
  
  <p><strong>What do I need to do to set text in the empty space on the attached screenshot?</strong></p>
