{
        //Tweet
        SLComposeViewController *twitterVC=[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
        //To send link together with text
        [twitterVC addURL:[NSURL URLWithString:@"https://twitter.com/IbrahimH_ss_n"]];
        //To add a photo to a link
        [twitterVC addImage:[UIImage imageNamed:@"image"]];
        //Sending link and Image with the tweet
        [twitterVC setInitialText:text];
        /* While adding link and images in a tweet the effective length of a tweet i.e.
        the number of characters which can be entered by the user decreases.
        The default maximum length of a tweet is 140 characters*/
        [self presentViewController:twitterVC animated:YES completion:nil];
