IAP Customized Recovery Transactions

I'm new to iOS and I'm wondering if there is an option to specify which completed transaction user wants to recover? I am currently using:

[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

And I can't find anything there to indicate exactly which transaction I want to recover.

Thank!

You are on the right track. Add to

[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];


And add the paymentQueueRestoreCompletedTransactionsFinished delegate function. In this function, you can bind a specific product ID.

- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
    NSMutableArray *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];

        if([productID isEqualToString:IN_APP_KEY_UNLOCK_SHIP_2])
        {
            //NSError *error = nil;
            [[NSNotificationCenter defaultCenter] postNotificationName:@"ship2PurchaseRestored" object:nil];
        }
    }

}
