UIAlertView enter Apple ID and Password IAP

Question

When I start test my IAP the system requests me apple id and password. There is an alert view with ok and cancel buttons.

I need to handle this button, because when I press on cancel button I need to make some action in app.

Very important: there is an autorize dialog not a purchase alert. I need to know how to process this action in app (for example if user tap on cancel button and after this autorize dialog disappear)

Answer 1

If you see only an authorize alert, not a purchase alert, that means you are trying to restore purchases.

If user taps on cancel button on authorize dialog, this delegate method gets called:

- (void)paymentQueue:(SKPaymentQueue *)queue restoreCompletedTransactionsFailedWithError:(NSError *)error;

Answer 2

You have to handle this case in failedTransaction delegate message:

- (void)failedTransaction:(SKPaymentTransaction *)transaction
{
    if (transaction.error.code != SKErrorPaymentCancelled)
    {
        // error!
    }
    else
    {
        // this is fine, the user just cancelled
        [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
    }
}
