Swift UIWebView 和 WKWebView

UIWebView使用方法：

(1)获取加载页面的Url地址，加载开始，加载完成，加载失败的监听

让当前的ViewController实现UIWebViewDelegate代理然后实现代理中的方法：

//使用UIWebView代理方法
    func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
        print(request.URL)
        if request.URL!.absoluteString.hasPrefix("app://") {
            //解析app://report?userId=0001逻辑
            return false
        }
        return true
    }
    func webViewDidStartLoad(webView: UIWebView) {
    //开始加载
         //activityLoadingView.startAnimating()
        // print(self.artworkWebView.request?.URL?.absoluteString)
    }
    func webView(webView: UIWebView, didFailLoadWithError error: NSError?) {
    //加载失败
       
    }
    func webViewDidFinishLoad(webView: UIWebView) {
    //加载成功，加载完成
       // activityLoadingView.stopAnimating()
        
    }

别忘了在viewDidLoad()方法中设置

 ziXunWebView.delegate =self

WKWebView使用方法：

导入包

import WebKit

实现代理WKUIDelegate,WKNavigationDelegate,WKScriptMessageHandler

如果不用到js交互，第三个代理WKScriptMessageHandler可以不用实习

实现代理方法：

    

// WKWebView的代理方法

    func userContentController(userContentController:WKUserContentController, didReceiveScriptMessage message:WKScriptMessage) {

      

    }

    func webView(webView:WKWebView, didStartProvisionalNavigation navigation:WKNavigation!) {

        //开始加载

        

    }

    func webView(webView:WKWebView, didFinishNavigation navigation:WKNavigation!) {

        //加载完成

       

    }

    overridefunc didReceiveMemoryWarning() {

        super.didReceiveMemoryWarning()

        // Dispose of any resources that can be recreated.

    }

  

WKWebView获取当前网页的url:

func webView(webView: WKWebView, decidePolicyForNavigationAction navigationAction:WKNavigationAction, decisionHandler: (WKNavigationActionPolicy) ->Void) {

        //var url:NSURL = navigationAction.request.URL!;

        //var urlstring:NSString = url.absoluteString

       

        var urlString:NSString! = navigationAction.request.URL?.absoluteString

        

       /*

        if (navigationAction.navigationType == WKNavigationType.LinkActivated && !navigationAction.request.URL!.host!.lowercaseString.hasPrefix("http://app.manyiaby.com/")) {

            print("fefe")

            UIApplication.sharedApplication().openURL(navigationAction.request.URL!)

            decisionHandler(WKNavigationActionPolicy.Cancel)

        } else {

            decisionHandler(WKNavigationActionPolicy.Allow)

        }

     */

       decisionHandler(WKNavigationActionPolicy.Allow)//一定要加上这一句代码不然会出异常

    }

获取wkWebView获取当前的title:

别忘了在viewDidLoad()方法中设置

 ziXunWebView.delegate = self
