title: reloading UIWebView makes it blank
body: <p>I am loading a webpage in a UIWebView using the following method</p>
  
  <pre><code> [NSURLConnection sendAsynchronousRequest:request
                                      queue:loadingQueue
                          completionHandler:^(NSURLResponse *response,
                                             NSData *data,
                                             NSError *error) {
                              if(!error) {
                                  [_webView loadData: data
                                            MIMEType: [response MIMEType]
                                    textEncodingName: [response textEncodingName]
                                             baseURL:nil];
                             }
                         }];
  </code></pre>
  
  <p>Firstly, for a few pages the images are not loaded at all. And secondly, when I refresh a page later by</p>
  
  <pre><code>      [_webView reload];
  </code></pre>
  
  <p>The web view turns blank. </p>
  
  <p>Does anyone know what's happening here?</p>
  
  <p>TIA,
  Nikhil</p>
