Answer 1

Try this,

1) Assign tag for each button

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

2) Then check your common button action

func buttonClicked(sender: UIButton)
{
   switch sender.tag {
   case 1: self.sender.hidden = true //button1
           break;
   case 2: self.sender.hidden = true //button2
           break;
   case 3: self.sender.hidden = true //button3
           break;
   case 4: self.sender.hidden = true //button4
           break;
   default: ()
           break;
   }

}
