Use the Delegate to Determine the Navigation Type!

My Snippet

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


    if (navigationType == UIWebViewNavigationTypeLinkClicked){

        NSURL *url = request.URL;
        [self openExternalURL:url];//Handle External URL here

    }

    return YES;

}

Implementing this is simple. Everytime a webview wants to load something, it will call 

webView:shouldStartLoadWithRequest:navigationType

which passes in the url associated with the hyperlink. Here, you can parse the NSURLRequest argument and handle what you want to do in native code.

(Remember, return NO to stop the UIWebView from actually loading the link afterwards)

By "label" do you mean "link"? If so, give the UIWebView a delegate and implement webView:shouldStartLoadWithRequest:navigationType. It will be called any time the user taps a link in the UIWebView.
