title: Remove tab from UITabBar without UITabBarController
body: <p>I'm using a UITabBar without a controller. I want to remove tabs from the UITabBar if certain conditions are met. For example, my UITabBar has 4 tabs set up in interface builder. If the scores module is not enabled at compile time, it should remove the scores tab. </p>
  
  <pre><code>// defined in IB
  #define kTabScores 1 
  UITabBar *_tabBar;
  
  
  // in viewDidLoad
  #if !INCLUDE_SCORES_SUPPORT
      // this doesn't seem to work
      [[_tabBar viewWithTag:kTagScores] removeFromSuperview];
  #endif
  </code></pre>
