Set Max Character Length UITextField

//While the UITextField class has no max length property, it's relatively simple to get this functionality by setting the text field's delegate and implementing the following delegate method:


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

    NSUInteger newLength = [textField.text length] + [string length] - range.length;

    return (newLength > 15) ? NO : YES;

}
