title: iOS7 how to completely hide status bar throughout app?
body: <p>I'm building a sprite kit game, and normally status bar does not show within my app. However, the drag and drop code that I'm using is doing something with the window and when the item is being dragged, the status bar flickers on and off. So my question is:</p>
  
  <p><strong>How can I completely and utterly tell iOS7 to hide status bar everywhere within my app?</strong></p>
  
  <p>I tried plugging per controller code, but cannot seem to find which particular controller is showing the status bar.</p>
  
  <pre><code>- (BOOL)prefersStatusBarHidden
  {
      return YES;
  }
  </code></pre>
  
  <p>I have status bar set to initially hidden in plist:

  <p>I tried using <code>setStatusBarHidden</code> within <code>appDidFinishLaunching</code></p>
  
  <p>Maybe there's some centralized setting I can set to off?</p>
