Prevent CGAffineTransfromScale from scaling outside of self.view

I am using this method to scale an imageView. 

-(IBAction)handlePinching:(UIPinchGestureRecognizer *)recognizer {
  recognizer.view.transform = CGAffineTransformScale(recognizer.view.transform, recognizer.scale,recognizer.scale);
  recognizer.scale = 1;
}

How do I prevent my imageView from scaling outside of self.view? I don't want any part of of my imageView to ever scale outside of the self.view.

Set clipsToBounds to YES on your view to prevent any drawing of subviews outside the bounds of your view:

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.view.clipsToBounds = YES;
}
