        self.button?.setTitleColor(UIColor.whiteColor(), forState: UIControlState.Normal)
    }
    func buttonClick(button:UIButton) {
        print(button.titleForState(UIControlState.Normal))

        self.imageView = UIImageView(frame: CGRect(x: 0, y: 64, width: (self.view.bounds.size.width), height: 200))
        self.view.addSubview(self.imageView!)
        self.imageView?.image = image_one
        // 添加手势
        self.imageView?.isUserInteractionEnabled = true
        let target = UITapGestureRecognizer(target: self, action: #selector(tageClick))
