title: ModalViewController frame moving
body: <p>I'm not sure if I can do this in this way, but let's have a try with smarter people then me.</p>
  
  <p>I want to be able to move the frame of presented controller by dragging it. I'm expecting to see controller in which I've invoked the [self presentModalViewController:anotherVC animated:YES]; below the presented one. I'm seeing white background thou.</p>
  
  <p>In order to achive  this functionality without presenting modal view controller I could add subview i.e.:</p>
  
  <pre><code>[self.view addSubview:anotherVC.view];
  </code></pre>
  
  <p>But is there a way to move modal presented view controller and be able to see view from which this modal controller is presented in?</p>
