title: webViewDidFinishLoad not firing when UIWebView opens a PDF
body: <p>Here is my code:</p>
  
  <pre><code>- (BOOL) webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request  navigationType:(UIWebViewNavigationType)navigationType;  {
  /* Add Content Loading Banner */
  if (navigationType == UIWebViewNavigationTypeLinkClicked) {
      [self.view addSubview:linkLoadView];
      linkLoadView.alpha = 1.0;
  }
  
  /* Handle PDF Opening */
  NSURL *url = [request URL];
  NSString *urlString = [url absoluteString];
  if([urlString rangeOfString:@".pdf"].location == NSNotFound){
      return true;
  } else {
      NSURL *filePath = [NSURL URLWithString:urlString];
      NSURLRequest *requestObj = [NSURLRequest requestWithURL:filePath];
      [pdfViewer loadRequest:requestObj];
      [self.view addSubview:topView];
      [self.view addSubview:linkLoadView];    
      return false;
  }   
  </code></pre>
  
  <p>}</p>
  
  <p>Basically what this does is detect a PDF link from within my UIWebView webView and loads it into an additional UIWebView pdfViewer (found on a View called topView). I then have a function as below:</p>
  
  <pre><code>- (void) webViewDidFinishLoad:(UIWebView *)theWebView{
          //for webView
          [UIView animateWithDuration:2
                   animations:^{
                        loadingView.alpha = 0.0;
                        linkLoadView.alpha = 0.0;
                   }
                   completion:^(BOOL finished){
                       [loadingView removeFromSuperview];
                       [linkLoadView removeFromSuperview];
                   }];
  
  }
  </code></pre>
  
  <p>The above function doesn't fire at all for the pdfViewer web view, but does for the webView web view. How do I fix this?</p>
  
  <p>Here is my setup settings for both webViews, on the viewDidLoad method.</p>
  
  <pre><code>//Options for 
  webView.delegate = self;
  webView.scalesPageToFit = YES;
  for (id subview in webView.subviews)
      if ([[subview class] isSubclassOfClass: [UIScrollView class]])
          ((UIScrollView *)subview).bounces = NO;
  
  //Options for 
  pdfViewer.delegate = self;
  pdfViewer.scalesPageToFit = YES;
  for (id subview in pdfViewer.subviews)
      if ([[subview class] isSubclassOfClass: [UIScrollView class]])
          ((UIScrollView *)subview).bounces = NO;
  </code></pre>
