title: Pass response from AFHTTPRequestOperation to UIWebview
body: <p>My code is making two requests to the server.  One into the uiwebview directly and one with the AFHTTPRequestOperation.  I'd like to use the AFHTTPRequestOperation and just pass the response into my uiwebview.  What is the correct syntax for passing the response into the uiwebview and not loading it again?   How do I do that without calling twice from the server?  I still want to be able to test the success or failure of the load request and also send username and password to connect to the url.</p>
  
  <pre><code>- (BOOL)textFieldShouldReturn:(UITextField *)textField {
  [itemField resignFirstResponder];
  
  NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
  NSString *userName = [defaults objectForKey:@"storedUserName"];
  NSString *passWord = [defaults objectForKey:@"storedPassWord"];
  
  NSURL *url = [NSURL URLWithString:@"http://www.example.net/"];
  AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL: url];
  
  [client setAuthorizationHeaderWithUsername:userName password:passWord];
  
  NSMutableURLRequest *request = [client requestWithMethod:@"GET" path:[@"/example/itemlookup.php?item=" stringByAppendingString:itemField.text] parameters:nil];
  
  AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
  
  [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
  
      //calling again here was the only way I could figure out to get this into my webview
      //need to get response from above and put into the uiwebview
      [webView loadRequest:request];
      NSLog(@"Success");
  } failure: ^(AFHTTPRequestOperation *operation, NSError *error) {
      NSLog(@"Failure"); 
  }];
  
  NSOperationQueue *queue = [[NSOperationQueue alloc] init];
  [queue addOperation:operation];
  
  
  return YES; 
  }
  </code></pre>
