title: Creating our own crop rect in camera overlay
body: <p>I want to state my basic requirement which is to change the frame for crop rect in <code>UIImagePickerController</code> for a camera.</p>
  
  <p>I just realized that it is not possible to change frame for crop rect. That leaves me with only one option i.e to create my own camera overlay wherein I can set frame for crop rect. I searched a lot but found nothing. I asked <a href="https://stackoverflow.com/questions/10100220/how-to-use-uiimagepickercontrollercroprect">previously</a> but didn't get anything. I don't even know is it possible and if yes then how to create it and move the crop box, scale it in accordance to default <code>UIImagePickerController</code> crop rect.  </p>
