Click on links within a UIWebView while browsing m.youtube.com on an iOS device

Utilizing uiwebview within my iOS application has been a great experience. I have successfully integrated a textbox above it that allows for seamless navigation of the web content. One particular example involves loading m.youtube.com, conducting a search on youtube.com, and smoothly transitioning to the video page upon selection. However, I am faced with the challenge of capturing the URL link of the video page in order to watch the selected video: m.youtube.com/watch?v=sa+2DFdfd . The question remains - how can this be achieved?

Key observations:

Upon testing this functionality on an iPhone 5 using Safari, I observed that the navigation bar dynamically adjusts based on the current webpage. For instance, when visiting m.youtube.com/watch?v=34124S on Safari, the updated URL is clearly visible in the browser. Unfortunately, replicating this behavior within the uiwebview has proven challenging as I struggle to retrieve the latest loaded webpage link.

The ShouldLoadStart method seems to function only during the initial page load. Subsequent clicks on the webpage, especially those involving JavaScript links, tend to go unnoticed by the delegates. This limitation prevents me from efficiently capturing URLs such as m.youtube.com/watch?v=34124S as seamlessly as Safari does on YouTube pages. Any assistance in resolving this issue would be greatly appreciated.

To store the URL, you can use the following code snippet:

NSString *url = [webView stringByEvaluatingJavaScriptFromString:@"window.location"];

Alternatively, you can also access the URL like this:

url = currentWebView.request.URL.absoluteString;

These methods can be implemented in the following delegate method:

-(void)webViewDidFinishLoad:(UIWebView *)webView

Another way to achieve this is by using the following code within the webViewDidFinishLoad method:

-(void)webViewDidFinishLoad:(UIWebView *)webView
{
  NSLog(@"%@",webView.request.mainDocumentURL);

 [_activityindicator stopAnimating];
}

You should add the following code snippet to your webview delegate class:

- (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType 
{
    //RECORD USER CLICKS ON LINKS.
    NSURL *url = [request URL];
    NSLog(@"clicked link: %@",[url absoluteString]);

    return YES;
}

Through the central notification feature, I was able to obtain the link. When the video is displayed in full view, I seize that specific event and extract the inner HTML of the loaded pages to retrieve the unique link.

I encountered a similar problem as well. One possible solution is to switch to using WKWebView.

With UIWebView, the only way I could get the current URL was by using JavaScript:

    [webView stringByEvaluatingJavaScriptFromString: @"location.href"];

Another issue I faced was that shouldStartLoadWithRequest wasn't being triggered. To work around this, you can intercept requests with NSURLProtocol (though this isn't possible with WKWebView) or simply check the current URL every second using a timer :)
