title: Hide status bar even when an alert is presented
body: <p>I am hiding my status bar on a specific <code>viewController</code> using </p>
  
  <pre><code>override func prefersStatusBarHidden() -&gt; Bool {
      return true
  }
  </code></pre>
  
  <p>It is working very nice until I present an alert on the screen. When alert is presented status bar appears again, Which I do not want. When alert is dismissed status bar is hidden again.</p>
