Set UITextField Maximum Length [duplicate]

Answer 1

this is how i resolved that problem. When max limit is reached it wont try to add more... you will only be able to remove chars

#define MAX_SIZE ((int) 5)
...

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
    if ([textField.text length] >= MAX_SIZE && ![string isEqualToString:@""]) {
        return NO;
    }

    return YES;
}
