How can I get the product identifier from a restored transaction?

Question

I have managed to restore in-app transactions and get the transaction identifier from the original transaction, but how do I identify the product which were bought in the transaction? Is it possible to get the product identifier for a previously purchased in-app product?

if you mean you want to check the purchased items that already user buy it .. yes you can do like this

- (void) checkPurchasedItems {     [[SKPaymentQueue defaultQueue] restoreCompletedTransactions]; } //You Call This Function  //Then this delegate Function Will be fired - (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue {     purchasedItemIDs = [[NSMutableArray alloc] init];      NSLog(@"received restored transactions: %i", queue.transactions.count);     for (SKPaymentTransaction *transaction in queue.transactions) {         NSString *productID = transaction.payment.productIdentifier;         [purchasedItemIDs addObject:productID];     } }
