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");

}
