I can able to do pinch zoom using pinch gesture using swift. But after image enlarges, i can't able view the which is out of view. (i.e)can't able to move image around the screen. Can any one help me?

My code:

@IBAction func scaleImage(sender: UIPinchGestureRecognizer) {
    sender.view!.transform = CGAffineTransformScale(sender.view!.transform, sender.scale, sender.scale)

    sender.scale = 1
  }

I need to view full image after zooming it.
