title: Can we share Video on FB using SLComposeViewController?
body: <p>I have used SLComposeViewController to share image and url's as follows:</p>
  
  <pre><code>  SLComposeViewController *fbComposer =
    [SLComposeViewController
     composeViewControllerForServiceType:SLServiceTypeFacebook];
  
    if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
    {
     SLComposeViewControllerCompletionHandler __block completionHandler=
     ^(SLComposeViewControllerResult result){
  
      [fbComposer dismissViewControllerAnimated:YES completion:nil];
  
      switch(result){
       case SLComposeViewControllerResultCancelled:
       default:
       {
        NSLog(@"Cancelled.....");
       }
        break;
       case SLComposeViewControllerResultDone:
       {
        NSLog(@"Posted....");
        UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Sent"
                                                         message:nil
                                                        delegate:nil
                                               cancelButtonTitle:@"Dismiss"
                                               otherButtonTitles: nil];
        [alert show];
       }
        break;
      }};
      NSString *message=@"posting to FB test";
     [fbComposer setInitialText:message];
     [fbComposer addImage:[UIImage imageNamed:@"2.jpg"]];
     [fbComposer addURL:[NSURL URLWithString:@"http://www.youtube.com/watch?v=GoZ2Be2zLq8"]];
     [fbComposer setCompletionHandler:completionHandler];
     [self presentViewController:fbComposer animated:YES completion:nil];
    }
  </code></pre>
