Transaction comes back after finishTransaction: has been called on it

Question

I am using in-app purchase for an iPhone app. I have a class that acts as SKProductsRequestDelegate and SKPaymentTransactionObserver, and it\'s all

Answer 1

I had the same issue but I solved it.

Here's my code:

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
    for (SKPaymentTransaction * transaction in transactions)
    {
        switch (transaction.transactionState)
        {
            case SKPaymentTransactionStatePurchased:
                [self completeTransaction:transaction];
                break;
            case SKPaymentTransactionStateFailed:
                [self failedTransaction:transaction];
                break;
            case SKPaymentTransactionStateRestored:
                [self restoreTransaction:transaction];
                break;
            default:
                break;
        }
    }
}

- (void)completeTransaction:(SKPaymentTransaction *)transaction
{
    NSLog(@"completeTransaction... %@", [[transaction class] description]);

    [self provideContentForProductIdentifier:transaction];
}

- (void)restoreTransaction:(SKPaymentTransaction *)transaction
{
    NSLog(@"restoreTransaction...");

    [self provideContentForProductIdentifier:transaction.originalTransaction];
}

I was then calling finishTransaction: method inside provideContentForProductIdentifier: method. And in case of restore transaction I was calling finishTransaction: to the originalTransaction object not the transaction itself.

I solved my issue by this code (method restoreTransaction:)

- (void)restoreTransaction:(SKPaymentTransaction *)transaction
    {
        NSLog(@"restoreTransaction...");

        //Pass the main transaction object.
        [self provideContentForProductIdentifier:transaction];
    }
