title: How to let the red UIView cover the whole screen, expect from the navigation bar & status bar
body: <p>When I rotate the iPhone, I set the redview to this :
  Also, I set the rootViewController to hidden already...</p>
  
  <pre><code>[appDelegate.myRootViewController.tabBarController.tabBar setHidden:YES];
  redView.frame = CGRectMake(0, 0, 480, 320);
  </code></pre>
  
  <p>But seems that the tabbarcontroller still cover the redView,ow can I resolve it? Thank you.
  (I also try to set the tabbarcontroller's view to other position, but the redview still can't show in the whole screen, thank you.<img src="https://i.stack.imgur.com/kIQyA.png" alt="alt text">)</p>
