 1 class ViewController：UIViewController {
 2
 3 var webView：UIWebView！
 4 override func viewDidLoad() {
 5 super.viewDidLoad()
 6
 7 let bounds = UIScreen.main.bounds
 8 let frame = CGRect(x：0, y：40, width：bounds.width,
 height：bounds.height-40)
 9 webView = UIWebView(frame：frame)
 10 webView.backgroundColor = UIColor.clear
 11 self.view.addSubview(webView)
 12
 13 let loadHTML = UIButton(frame：CGRect(x：40, y：
 400, width：240, height：44))
 14 loadHTML.setTitle(“加载 HTML网页”, for：
 UIControlState.init(rawValue：0))
 15 loadHTML.backgroundColor = UIColor.brown
 16 loadHTML.addTarget(self, action：
 selector(ViewController.loadHTML), for：.touchUpInside)
 17
 18 let loadGIF = UIButton(frame：CGRect(x：40, y：470,
 width：240, height：44))
 19 loadGIF.setTitle(“加载GIF动画”, for：
 UIControlState.init(rawValue：0))
 20 loadGIF.backgroundColor = UIColor.brown

 selector(ViewController.loadGIF), for：.touchUpInside)
 22
 23 self.view.addSubview(loadHTML)
 24 self.view.addSubview(loadGIF)
 25 }
 26

 28 {
 29 let team = “<div style=‘color：#ff0000;font-size：

 30 let tel = “<div>电话：15011122222</div>”
 31 let url = “<div><b>网址：
 http：//www.coolketang.com</b></div>”
 32 let html = team + tel + url
 33 webView.dataDetectorTypes =
 [UIDataDetectorTypes.link,
 UIDataDetectorTypes.phoneNumber]
 34 webView.loadHTMLString(html, baseURL：nil)
 35 }
 36
 37 func loadGIF()
 38 {
 39 let resourceURL = Bundle.main.resourceURL
 40 webView.loadHTMLString(“<img
