title: Xcode fullscreen window without titlebar
body: <p>I would like to create a full screen application (mac) but eventhough I have the window fullscreen;
  <code>[window setFrame:[window frameRectForContentRect:[[window screen] frame]]display:YES animate:YES];</code></p>
  
  <p>I can't get rid of the title bar? Can you change the above code to make the window without a titlebar or do you have to do it completely different? Thanks :)</p>
