SLComposecontroller does not disable post button for long messages

Question

I used SLComposerController, but it is not disabling the post button when the character count exceeds 140 character . I want to post an URL ,image and initial text on Twitter via my iOS application. How to do this?

It is up to the user to set the correct length to send, but I think it won't send if it is too long, or give you a callback if it didn't work.

Here is what I did:

-(void) postOnTwitterInsideView:(UIViewController *)viewController 
                        message:(NSString *)postMessage{

    if( [SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter] ){
        SLComposeViewController *twitterPost = [SLComposeViewController
                                                composeViewControllerForServiceType:SLServiceTypeTwitter];

        [twitterPost setCompletionHandler:^(SLComposeViewControllerResult result){
            switch (result) {
                case SLComposeViewControllerResultDone:
                    // tell user message was sent
                    break;

                case SLComposeViewControllerResultCancelled:
                    // tell user message was not sent
                    break;
                default:
                    break;
            }
        }];

        [twitterPost addImage:self.imagePost];
        [twitterPost setInitialText:postMessage];
        [viewController presentViewController:twitterPost 
                                     animated:YES 
                                   completion:nil];
    } else {
        // tell user he has to activate this service in his settings of iOS
    }
}
