TWTweetComposeViewController Character Length Problem

[IphoneSdk]

I'm using the TWTweetComposeViewController so only 140 characters can be posted to Twitter.

Here is the code:

TWTweetComposeViewController *twitter = [[TWTweetComposeViewController alloc] init];
    NSString *emailString = [[NSString alloc] initWithFormat:@"%@ %@ %@", label1.text, label2.text, label3.text];
    
    [twitter setInitialText:emailString];
    
    [self presentViewController:twitter animated:YES completion:nil];

label1, label2 and label3 are all inputed by the user, therefore emailString doesn't have a certain character length. The problem is, if emailString has a character greater than 140, none of the string appears in the TWTweetComposeViewController.

What do you think the best way to fix this is?

Thanks

Setup a character count label and actively count the characters as the user is typing. When they reach the limit, do not allow them type anymore. This is the UITextField delegate method you'll be looking at:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string

It is called whenever the user adds or deletes a character.

Sorry, I didn't explain it right. I meant the user inputs it from there music library so the different labels are like artist, song and album. So I can't really control how many characters they have.

Sorry for explaining it badly!

That's not really a problem with code then, you have to first figure out what you want to do when their selections exceed 140 characters. After that, I figure it would be pretty easy to implement it. I don't really have a solution except truncating the textfields equally but that seems like a bad idea.

Ok thanks. I'll see how it goes.
