        SLComposeViewController *socialController = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

        // add initial text
        [socialController setInitialText:@"Hello Facebook!"];

        // add an image for you optional 
        [socialController addImage:[UIImage imageNamed:@"picture.jpg"]];
