Multiple receipt count for restoreCompletedTransaction inapp purchasing

Question

I have an autorenewable subscription. When the app is installed on a new device, Apple returns ALL previous purchase receipts, in this case since it is sandbox I get 6 receipts every time I install. The observer then sends the queue for restoredCompleted transactions. I have a method to send the transaction to my server for Apple verification, but it runs 6 times because of the 6 receipts. I really only want to deal with the LAST receipt sent.

So I am trying to count the transactions in the queue and ONLY verify the receipt when the count reaches 1.

Here is what I have so far:

    - (void)paymentQueue: (SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {
if (myQueue == nil) {
    myQueue = [SKPaymentQueue defaultQueue];
}

NSLog(@"Transactions in Array  in My Store %@", [queue transactions]); 
tCount =myQueue.transactions.count;
NSString *transCount =  [NSString stringWithFormat:@"%d",tCount];

for (SKPaymentTransaction *transaction in transactions)       

{ switch (transaction.transactionState)     

    { case SKPaymentTransactionStatePurchased:
            [self completeTransaction: transaction];
            break;

        case SKPaymentTransactionStateFailed:
            [self failedTransaction: transaction];
            break;

        case SKPaymentTransactionStateRestored:                

            if  ([transCount isEqualToString:@"1"]) {
                [self restoreTransaction: transaction];
            }

            else {
               tCount--;

                dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void) {
                    [[SKPaymentQueue defaultQueue] finishTransaction: transaction];
                });
            }


        default:
            break;

          }
      }
    return;        
   }

The restore cycles through, but the count does not decrement. This is probably something simple and dumb. Can someone show me how to decrement this count?

Thanks!

Shouldn't you place an int before tCount =myQueue.transactions.count; to declare tCount as an integer? – Appraisal

Answer 1

I wait until restoreCompletedTransactionsFinished before sending a receipt to my server to verify with Apple. This eliminates sending every receipt, which after a few months could get onerous. So, no need to decrement to transaction cout.
