title: facebook app requests notifications doesn't appear
body: <p>Actually I need to add the app requests concept in my app. For that I have used following code :</p>
  
  <pre><code>     [FBWebDialogs
       presentRequestsDialogModallyWithSession:[FBSession activeSession]
       message:@"Try this app"
       title:nil
       parameters:params
       handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
           if (error) {
               NSLog(@"Error sending request.");
           } else {
               if (result == FBWebDialogResultDialogNotCompleted) {
                   NSLog(@"User canceled request.");
               } else {
                   NSDictionary *urlParams = [self parseURLParams:[resultURL query]];
                   if (![urlParams valueForKey:@"request"]) {
                       NSLog(@"User canceled request.");
                   } else {
                       NSString *requestID = [urlParams valueForKey:@"request"];
                       NSLog(@"Request ID: %@", requestID);
                   }
               }
           }
       }];
  
  
    - (NSDictionary*)parseURLParams:(NSString *)query 
      {
   NSArray *pairs = [query componentsSeparatedByString:@"&amp;"];
   NSMutableDictionary *params = [[NSMutableDictionary alloc] init];
    for (NSString *pair in pairs) {
      NSArray *kv = [pair componentsSeparatedByString:@"="];
      NSString *val =
      [kv[1] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
      params[kv[0]] = val;
    }
    return params;
  
   }
  </code></pre>
  
  <p>I also looked upon this facebook documentation <a href="https://developers.facebook.com/docs/reference/dialogs/requests/#frictionless_requests" rel="nofollow">App requests</a></p>
  
  <p>But when I send request to any of my friend, I got the request id but that notification doesn't appear on my friend facebook account. What I am doing wrong with above code?</p>
