NSURLSession is not downloading full webpage

Question

I'm currently attempting to download a webpage using a NSURLSession in order to retrieve a status update on the download progress. Unfortunately, after downloading the webpage, when I go to load the webpage, there are visual issues (missing images, missing javascript, missing styles, etc), leaving the webpage looking broken and in complete. When loading directly to the webView, everything loads correctly. I would like to know if there is a way (or anything I'm missing) to download ALL aspects of the webpage and load them up so I may load the full webpage and display a loading bar while the page loads.

   - (void)loadRequest:(NSURLRequest *)request
{
    NSURLSessionConfiguration *sessionConfig = [NSURLSessionConfiguration defaultSessionConfiguration];
    self.urlSession = [NSURLSession sessionWithConfiguration:sessionConfig delegate:self delegateQueue:[NSOperationQueue mainQueue]];
    self.downloadTask = [self.urlSession downloadTaskWithRequest:request];
    [self.downloadTask resume];
}

    - (void)URLSession:(NSURLSession *)session downloadTask:(NSURLSessionDownloadTask *)downloadTask didFinishDownloadingToURL:(NSURL *)downloadURL
{
    [_webView loadData:[NSData dataWithContentsOfURL:downloadURL] MIMEType:downloadTask.response.MIMEType textEncodingName:downloadTask.response.textEncodingName baseURL:nil];
}

I was having similar problems (missing images etc.). You need to provide a baseURL. Try:

[_webView loadData:[NSData dataWithContentsOfURL:downloadURL] MIMEType:downloadTask.response.MIMEType textEncodingName:downloadTask.response.textEncodingName baseURL:downloadTask.response.URL];
