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; }}
