Swift-确定使用开关按下哪个按钮

试试这个，

1）为每个按钮分配标签

Button1.tag=1Button2.tag=2Button3.tag=3Button4.tag=4

2）然后检查您的常用按钮动作

func buttonClicked(sender: UIButton){   switch sender.tag {   case 1: self.sender.hidden = true //button1break;   case 2: self.sender.hidden = true //button2break;   case 3: self.sender.hidden = true //button3break;   case 4: self.sender.hidden = true //button4break;   default: ()break;   }}
