How to remove gesture after implementing UIGestureRecognizer

I am using PinchGestureRecognizer and RotationGestureRecognizer both working fine. The code is as follows:

- (IBAction)pinchDetected:(UIPinchGestureRecognizer *)recognizer {

    recognizer.view.transform = CGAffineTransformScale(recognizer.view.transform, recognizer.scale, recognizer.scale);
    recognizer.scale = 1;
}


-(IBAction)rotationDetected:(UIRotationGestureRecognizer *)recognizer
{
    recognizer.view.transform = CGAffineTransformRotate(recognizer.view.transform, recognizer.rotation);
    recognizer.rotation = 0;
}

with this code I am able to pinch as well as rotate my view. but on "RESET" button click I want to set my view's frame as it was before pinching or rotating.

for that I am using 

[viewTwo setFrame:CGRectMake(80.0f, 65.0f, 160.0f, 101.0f)];

but my frame does not set.

so How can I set my view's frame again as it was before pinching and zooming?

You are not changing the frame with your gesture recognisers.

You need to assign the transform back to the identity.

recognizer.view.transform = CGAffineTransformIdentity;

Frame and transform are applied to a view in two completely separate ways (where frame is the smallest rectangle that fits a view, and transform is a representation of the underlying 2-D matrix of the view). If you wish to return to the size the view was previously, assign recognizer.view.transform to CGAffineTransformIdentity.
