title: ios Social Framework Duplicate Tweet issue
body: <p>I'm using <code>Social Framework</code> in iOS  for Twitter integration</p>
  
  <pre><code>SLComposeViewController * composeVC  = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
  
  success = [composeVC setInitialText:[NSString stringWithFormat:@"xxx"]];
  SLComposeViewControllerCompletionHandler myBlock = ^(SLComposeViewControllerResult result)
  {
  
       if (result == SLComposeViewControllerResultCancelled)
       {
       }
       else
       {
           [self shareApiCall:service];
        }
  
        [composeVC dismissViewControllerAnimated:YES completion:Nil];
  };
  </code></pre>
  
  <p>As we are tweeting the same thing, it gives success in code, but then duplicate popup show. Is there any way we can know that the posted tweet was a duplicate tweet (through code)?</p>
