title: iPhone SDK: Image picker allows editing question
body: <p>In my app I use an image picker, and I can set the picker to allow editing, using:</p>
  
  <pre><code>self.imgPicker.allowsImageEditing = YES;
  </code></pre>
  
  <p>Now although this works, is there a way to customise the crop region this offers to a certain size?  I've been searching around on the net for it, and I don't seem to be getting anywhere.</p>
  
  <p>Any help? Thanks.</p>
