Ho un'applicazione con nell'integrazione applicazione in esso. Nella mia app ho due pulsanti per acquistare e sottoscrivere un'app a pagamento. Quando l'utente fa clic su acquista, controlla la convalida di Apple e acquista il prodotto.Come verificare se un prodotto è già stato acquistato utilizzando l'acquisto in app in iOS?
Questo funziona correttamente, ma quando il prodotto è stato acquistato il mio tasto del buy dovrebbe cambiare a 'fare' e quando l'applicazione è prossima volta eseguito il pulsante Acquista non deve essere visibile per quel particolare prodotto. Dovrebbe essere mostrato il pulsante 'done'. Il mio problema è quando un prodotto viene acquistato viene visualizzato il pulsante Acquista invece di pulsante fatto.
Questo è il mio codice:
-(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];
}
else if (transaction.error.code == SKErrorPaymentCancelled) {
// [self showAlert:@"In-App Purchase" withMessage:@"This device is not allowed to make the payment."];
NSLog(@"User Cancellation.");
}
else {
// SKErrorUnknown
NSLog(@"Unknown Reason.");
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];
// return;
//[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}
