title: status bar and Navigation bar problem after dismissed modal view
body: <p>the apps launched the mailcomposer modal view (MFMailComposeViewController) when the Contact Us button is pressed.
  but once the modal view is loaded, the status bar is hidden automatically. </p>
  
  <p>I setStatusBarHidden Status to NO after modal view controller is dismissed.</p>
  
  <pre><code>[self dismissModalViewControllerAnimated:YES];
  [[UIApplication sharedApplication] setStatusBarHidden:NO];
  </code></pre>
  
  <p>but the status bar and navigation bar is overlapped after ModalViewController is dismissed.</p>
  
  <p>I got no clue how to fix it. 
  Appreciate any kind help.
  Thanks.</p>
