Swift基础之UIImageView（都是2.2版本）

//设置全局变量,将下面的替换即可

    //var myImgView = UIImageView();

    //系统生成的viewDidLoad()方法

    override func viewDidLoad() {

        super.viewDidLoad()

        // Do any additional setup after loading the view, typically from a nib.

        

        //创建局部变量UITextField

        let myImgView = UIImageView.init(frame: CGRectMake(80, 100, 100, 100));

        //设置背景颜色

        myImgView.backgroundColor = UIColor.cyanColor();

        //添加图片

        myImgView.image = UIImage(named: "per_info_boy.png");

        //设置图片边框

        myImgView.layer.borderWidth = 2;

        //设置边框颜色

        myImgView.layer.borderColor = UIColor.lightGrayColor().CGColor;

        //设置圆角

        myImgView.layer.cornerRadius = 50;

        //设置是否裁剪多余边缘

        myImgView.clipsToBounds = true;

        //设置图片的触摸事件(手势)

        let myTapGesture = UITapGestureRecognizer.init(target: self, action: #selector(imgTouch));

        //设置图片是否与用户交互

        myImgView.userInteractionEnabled = true;

        //设置图片的手势

        myImgView.addGestureRecognizer(myTapGesture);

        

        

        //添加视图

        self.view.addSubview(myImgView);

    }

    //实现触摸事件方法

    func imgTouch(sender:UITapGestureRecognizer!)

    {

        print("触发了图片事件方法....");

        //2.2版本之后开发

        let imgV:UIImageView = sender.view as! UIImageView;

        

        imgV.image = UIImage(named: "per_info_girl.png");

    }
