Question

Got a simple question. I got a text field that gets updated and filled with character I want to perform actions when they have a length. for example when the length is 12 (12 character) I want it to do something and when the length is 24, etc.

Can I just do:

if (textfield.text.length == 12){
//do something
}

hope someone can help me out 🙂

thanks

you should use the delegate

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

and use the if you have created yourself inside it like

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
    if (textfield.text.length == 12){
    //do something
    }
}
