您可以编程方式尽可能简单地创建Web视图使用这段代码

you can create the web view programatically as simple as possible use this piece of code

override func viewDidLoad() {
    super.viewDidLoad()
    let webV:UIWebView = UIWebView(frame: CGRectMake(0, 0, UIScreen.mainScreen().bounds.width, UIScreen.mainScreen().bounds.height))
    webV.loadRequest(NSURLRequest(URL: NSURL(string: "http://www.google.co.in")))
    webV.delegate = self;
    self.view.addSubview(webV)
}

如果你想要使用此委托函数

and if you want use this delegate function

func webView(webView: UIWebView!, didFailLoadWithError error: NSError!) {
    print("Webview fail with error \(error)");
}
func webView(webView: UIWebView!, shouldStartLoadWithRequest request: NSURLRequest!, navigationType: UIWebViewNavigationType) -> Bool {
    return true;
}
func webViewDidStartLoad(webView: UIWebView!) {
    print("Webview started Loading")
}
func webViewDidFinishLoad(webView: UIWebView!) {
    print("Webview did finish load")
}
