title: How do I display an image in fullscreen mode?
body: <p>I'm almost there, just need a little helping hand from a kind soul. I have set up a method to allow a photo to be taken upon single tapping a UIView. That works perfectly. I have also set up a Double Tap gesture which is recognised and works as expected.</p>
  
  <p>However, I am trying to use the double tap to zoom on the photo which is held in the view. I am finding that the zoom happens, but it only expands the photo to the boundary of the UIView which is a box in the middle of the screen.</p>
  
  <p>How do I get the photo to be shown full screen and then to go back again?</p>
  
  <pre><code>- (IBAction)didDoubleTapPhoto1:(UITapGestureRecognizer *)sender; {
  
  
      NSLog(@"DoubleTap");
  
      self.photoView.contentMode = UIViewContentModeScaleAspectFill;
  
  }
  </code></pre>
  
  <p>Thank you.</p>
