    btn1.backgroundColor = UIColor.redColor()
    btn1.addTarget(self, action: "onClick:", forControlEvents: .TouchUpInside)
    btn1.tag = 1
    self.addSubview(btn1)

    btn2 = UIButton(frame: CGRect(x: UIScreen.mainScreen().bounds.width - 100, y: UIScreen.mainScreen().bounds.height - 100, width: 100, height: 100))
    btn2.backgroundColor = UIColor.yellowColor()
