如何訪問加載到webview上的HTML標籤並在外部瀏覽器上加載特定標籤？

Question

我用這種方法加載網頁流量： -

NSString *urlString = self.UrlToLoad; 

NSURL *url = [NSURL URLWithString:urlString]; 
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url]; 


[self.view_webView loadRequest:urlRequest]; 

self.view_webView.delegate=self; 

Answer 1

首先，你必須實現Web視圖的委託方法：

- (BOOL)webView:(UIWebView *)_webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType 

現在嘗試檢測要在Safari瀏覽器

打開網址

- (BOOL)webView:(UIWebView *)_webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType 
    { 
     NSString urlLoading = request.URL.absoluteString; 
     if ([urlLoading isEqualToString:@"url_that_you_want_to_load"]) { 
     [webView stopLoading]; 
     //open url in external browser 
     [[UIApplication sharedApplication] openURL:request.URL]; 
     } 
     return YES; 
    }
