import UIKit

class ViewController: UIViewController {

override func viewDidLoad() {

super.viewDidLoad()

// 本地图片的加载

// self .addimage()

//加载网络图片（非本地）

self.addRemoteImageView()

}

func addimage()

{

// 初始化uiimageview and uiimage

var uimageview = UIImageView(frame: CGRectMake(35,100,300, 300))

//设置加载一张本地图片

let image = UIImage(named:"cat.jpg")

//把加载好的图片丢给imageview中的image显示

uimageview.image = image

//把uiimageview加载到父控件上，也就是self.view

self.view.addSubview(uimageview)

}

//加载网络图片（非本地）

func addRemoteImageView()

{

var imageView = UIImageView(frame: CGRectMake(35, 300))

// 图片地址

let strUrl = "http://e.hiphotos.baidu.com/baike/c0%3Dbaike80%2C5%2C5%2C80%2C26/sign=410619fb3d01213fdb3e468e358e5db4/9f510fb30f2442a71525d087d543ad4bd11302ec.jpg"

//url

let url = NSURL(string: strUrl)

//图片数据

var data = NSData(contentsOfURL:url!)

//通过得到图片数据来加载

let image = UIImage(data: data!)

//把加载到的图片丢给imageView的image现实

imageView.image = image

//边框颜色设置

imageView.layer.borderColor = UIColor.redColor().CGColor

//边框的宽度设置

imageView.layer.borderWidth = 2

//圆角的设置

imageView.layer.cornerRadius = 150

// 最主要的一句

imageView.layer.masksToBounds = true

//把uiimageview加载到父控件上，也就是self.view

self.view.addSubview(imageView)
