独特的UIControl

Question

I have an UIButton and UISwitch . A user could touch both with one finger each at the same time and release - triggering 2 separate TouchUpInside @IBAction s.

How can I tell a control that it's touches must be exclusive, without creating a subclass?

Answer 1

UIControl是UIView的子类，因此您可以在任何UI控件上直接设置ExclusiveTouch = true 。
