如果通过在iPhone中捏UIButton来增加尺寸

Question

我有一个UIButton，想通过捏UIButton来增加UIButton的大小.UIButton是否有可能类似于UIImageView。

Answer 1

Yes it is. Just get the gesture and then scale your button accordingly.

Answer 2

Here you have nice tutorial with gesture recognizers. For pinching use UIPinchGestureRecognizer after hooking it up you can retrieve scale of pinching easily. In your case don't use affine transform to scale, because it will cause blurring of the button. Instead, you should calculate frame of button by hand. This is more complicated, but result should be exactly what you want.
