title: UITTabBarController customization (repositioning tabbar)
body: <p>I'm trying to reposition the tab bar in a UITabbarController. I know it's not a great idea but that's what I was asked to do. I managed to move the tabbar to the top of the screen with this:</p>
  
  <pre><code>self.tabBarController.tabBar.frame = CGRectMake(0, 0, 768, 68);
  </code></pre>
  
  <p>and it works great. Unfortunately, the content view is not repositioned accordingly. </p>
  
  <p>After I reposition the tab bar, I add the content view and try to adjust it manually, but it doesn't have any effect:</p>
  
  <pre><code>self.tabBarController.viewControllers = [NSArray arrayWithObjects:
          [[[HomeViewController alloc] initWithNibName:nil bundle:nil] autorelease], 
           nil];
  // dummy values for testing.
  self.tabBarController.selectedViewController.view.frame = CGRectMake(0, 69, 10 , 10);
  </code></pre>
  
  <p>What am I doing wrong?</p>
