Mam aplikacji z App integracji w nim. W mojej aplikacji mam dwa przyciski do kupowania i subskrybowania płatnej aplikacji. Kiedy użytkownik kliknie przycisk Kup, idzie sprawdzić, czy Apple zatwierdza i kupuje produkt.Jak sprawdzić, czy produkt został już zakupiony przy zakupie aplikacji w systemie iOS?
To działa prawidłowo, ale gdy produkt został zakupiony mój przycisk kupna powinien zmienić się na „Gotowe” i gdy aplikacja jest następnym razem uruchomić przycisk Kup nie powinny być widoczne dla danego produktu. Zamiast tego powinien zostać wyświetlony przycisk "zrobione". Mój problem polega na tym, że po zakupie produktu zamiast przycisku Gotowe wyświetlany jest przycisk Kup.
To jest mój kod:
-(void)checkPurchasedItems
{
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}
//Then this delegate Function Will be fired
- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
NSLog(@"received restored transactions: %i", queue.transactions.count);
for (SKPaymentTransaction *transaction in queue.transactions)
{
NSString *productID = transaction.payment.productIdentifier;
NSLog(@"%@",productID);
}
}
// called when a transaction has failed
- (void)failedTransaction:(SKPaymentTransaction *)transaction
{
if (transaction.error.code != SKErrorPaymentCancelled)
{
// error!
[self finishTransaction:transaction wasSuccessful:NO];
if (transaction.error.code == SKErrorClientInvalid) {
//[self showAlert:@"In-App Purchase" withMessage:INVALID_CLIENT];
}
else if (transaction.error.code == SKErrorPaymentInvalid) {
//[self showAlert:@"In-App Purchase" withMessage:PAYMENT_INVALID];
}
else if (transaction.error.code == SKErrorPaymentNotAllowed) {
//[self showAlert:@"In-App Purchase" withMessage:PAYMENT_NOT_ALLOWED];
}

// [self showAlert:@"In-App Purchase" withMessage:@"This device is not allowed to make the payment."];

}

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Transaction Status" message:@"Transaction Failed due to unknown reason" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
}
}
else {
// this is fine, the user just cancelled, so don’t notify
// UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Transaction Status" message:@"Transaction failed due to some reason" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
// [alert show];
