Use an UIPinchGestureRecognizer on the button to detect the gesture. Then resize the frame, or use an AffineTransform. (button.transform = CGAffineTransformMakeScale(scaleFactor,scaleFactor)).

Use the CGAffineTransformMakeScale like this

button.transform = CGAffineTransformMakeScale(1.2, 1.2)

scale it to normal

button.transform = CGAffineTransformMakeScale(1.0, 1.0)

If you want animation

[UIView animateWithDuration:0.3
                     animations:^{
                         button.transform = CGAffineTransformMakeScale(1.2, 1.2);
                     }
                     completion:NULL];
