Question

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?

Answer 1

You are not changing the frame with your gesture recognisers.

You need to assign the transform back to the identity.

recognizer.view.transform = CGAffineTransformIdentity;
