UITextField ignoring inputDelegate?

Question

Does UITextField ignore the inputDelegate? Using the following code:

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.textField.inputDelegate = self;
    NSLog(@"textField: %@", self.textField);
    NSLog(@"delegate: %@", self.textField.inputDelegate);
}

I get the following output:

2012-03-26 20:43:49.560 InputTest[33617:f803] textField: <UITextField: 0x6c093a0; frame = (20 20; 280 31); text = ''; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; layer = <CALayer: 0x6c094d0>>
2012-03-26 20:43:49.561 InputTest[33617:f803] delegate: (null)

It runs just fine, without warning or exception, and the delegate property works just fine. But setting the inputDelegate causes no change and the delegate methods are not called.

Have you declared the VC as a ? I imagine you would have, or else seen a compiler warning. — danh, Mar 27 '12 at 05:33
Hmm. I just tried it in a random view controller, even with the protocol warning, and my code - duplicate of yours - worked fine. — danh, Mar 27 '12 at 05:39

I have the same problem as you are facing. upon deep searching i found out that, though UITextInput Protocol was there in iOS 3.2 but UITextView/Field didn't make use of that protocol before iOS 5. Run your code in iOS 5 or later and it should work.

Set your delegate after the editing session has begun.

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
    [self.myTextfield setInputDelegate:self];
    NSLog(@"Inputdelegate is: %@", self.myTextField.inputDelegate);

    return YES;

}
