Question

In my interface I have:

@interface MainViewController : UIViewController <SKProductsRequestDelegate, SKPaymentTransactionObserver, UITextFieldDelegate> {
    UITextField *Stock;
    // ....
}

This is the implementation I have:

- (BOOL)Stock:(UITextField *)textField shouldChangeTextInRange:(NSRange)range  replacementText:(NSString *)text
{
    if([[textField text] isEqualToString:@"\n"]) {
        [textField resignFirstResponder];
        return NO;
    }    
    return YES;
} 

In the viewDidLoad I have Stock.delegate = self;

I am expecting this method is called after any character is typed in the text field. But this routine is never called. What is the problem?

Thanks

If this is a UITextField, you’ve just implemented a random method. The actual delegate method is

-textField:shouldChangeCharactersInRange:replacementString:

Try providing that one.
