Question

I have a UIView which I scale to 4x after tapping on it. It works fine. On the next tap I want to restore it back to original size. The problem is that it recognizes the tap only in the smaller rectangle the UIView had before scaling. I would like to recognize the tap anywhere in the scaled UIView. How can I achieve it?

//Tapping code
titleCard = [[UIView alloc] initWithFrame: myrect];
[self addSubview:titleCard];
[titleCard release];

UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(changeSize:)];
[tapRecognizer setNumberOfTouchesRequired:1];
[tapRecognizer setNumberOfTapsRequired:1];
[titleCard addGestureRecognizer:tapRecognizer];
[tapRecognizer release];

//Scaling code
CABasicAnimation *scale = [CABasicAnimation animationWithKeyPath:@"transform.scale"];
[scale setBeginTime:CACurrentMediaTime()+0.75];
[scale setDuration:0.5];
[scale setToValue: [NSNumber numberWithFloat:4.0f]];
[scale setRemovedOnCompletion:NO];
[scale setFillMode:kCAFillModeForwards];

Thanks.

I am not sure what does not work over here, i replaced the below code.

//Scaling code 
CABasicAnimation *scale = [CABasicAnimation animationWithKeyPath:@"transform.scale"]; 
[scale setBeginTime:CACurrentMediaTime()+0.75]; 
[scale setDuration:0.5]; 
[scale setToValue: [NSNumber numberWithFloat:4.0f]]; 
[scale setRemovedOnCompletion:NO]; 
[scale setFillMode:kCAFillModeForwards];
[titleCard.layer addAnimation:scale forKey:@"Scale"];

with

[UIView beginAnimations:@"Scale" context:nil];
[UIView setAnimationDelay:0.75];
[UIView setAnimationDuration:0.5];

[titleCard setTransform:CGAffineTransformMakeScale(4.0f, 4.0f);

[UIView commitAnimations];

Now the clicks are getting recognized all over the UIView and not just the smaller rectangle before the scaling happened.
