ios - UIWebView吸引用户点击链接

Question

当用户单击UIWebView上的任何链接时，我想执行一些操作。我这样做是为了使这项工作:

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
    NSLog(@"request - %@", request.URL.absoluteString);
    [webView.window makeKeyAndVisible];
    [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];
    if(isFirstTimeLoaded)
    {
        [self shoToolbar];
        [self updateButtons];
    }


    return YES;
}  

- (void)webViewDidFinishLoad:(UIWebView *)webView
{   
    isFirstTimeLoaded = YES;
}

这通常可以正常工作。但是，当 UIWebView的首次加载在加载页面时涉及多个重定向时，则不是这样。我要的是仅在用户有意单击链接时才触发这种情况。不在 UIWebView的url重定向上。

您必须检查navigationType

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

        if (navigationType==UIWebViewNavigationTypeLinkClicked) {
            // It was a link
        } else {
           // It wasn't a link
        }


        return YES;
    }
