I believe the link is really not shown. But, when you post it, the link will be added to your post on Facebook / Twitter.
Of course, you can just add a link to the text.
NSString *link = [NSString stringWithFormat:@"com.boxscoregames.squares://square?%@",squareID]; NSString *noteStr = [NSString stringWithFormat:@"You have been invited to join the Square game, please follow the link below on your iPhone. %@", link]; NSURL *url = [NSURL URLWithString:link]; UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:@[noteStr, url] applicationActivities:nil]; [self presentViewController:activityVC animated:YES completion:nil];
