Right now, our code is set to grab the text from the UITextField as setInitialText for Facebook/Twitter posts.
What we want to do i
If you want to append the text with URL, just use the addURL: method. It won't display any text in the SLComposeViewController's view. But will add the URL at the end after publishing users tweet.
SLComposeViewController *slComposeThirdViewController = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
[slComposeThirdViewController setInitialText:@"initial Text"];
[slComposeThirdViewController addURL:[NSURL URLWithString:@"http://stackoverflow.com/"]];
