title: UITabBarItem title not displayed
body: <p>I have a UITabBarController in which the first UITabBarItem title is not getting displayed.  I have it set in Interface Builder and have tried to set it programmatically, but the title area stays blank.</p>
  
  <pre><code>[[tabBarController.tabBar.items objectAtIndex:0] setTitle:@"Test1"];
  [[tabBarController.tabBar.items objectAtIndex:1] setTitle:@"Test2"];
  </code></pre>

  <p>(The Item 2 is set through Interface Builder, which is where that title is coming from, just to test that the IB titles are working as well -- except for the first one)</p>
  
  <p>I have a feeling this is the odd result of adding the UITabController to the project and dragging the existing view into the first spot, but don't know how to fix it.</p>
  
  <p>Here's the view in Interface Builder:

  <p>Moving the ViewController that's in the first spot to the second spot yields the result you'd expect -- the second spot becomes blank and the first gets set with "Test1", meaning it's not something funny with just the first spot.</p>
