SKPaymentTransaction transactionState购买后未成为SKPaymentTransactionStatePurchased

Question

我已经实现了应用内支付，就像苹果文档中关于IAP的描述一样，但当我在沙盒模式下尝试它们时，'transactionState‘永远不会更改为SKPaymentTransactionStatePurchased。(它会永远留在SKPaymentTransactionStatePurchasing上。)

有人知道哪里出了问题吗？

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

- (void)completeTransaction:(SKPaymentTransaction *)transaction
{
    [self recordTransaction:transaction];
    [self provideContent:transaction.payment.productIdentifier];
    [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}

- (void)failedTransaction:(SKPaymentTransaction *)transaction
{
    if (transaction.error.code != SKErrorPaymentCancelled) {
        [NSAlert alertWithError:transaction.error];
    }
    [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}

- (void)restoreTransaction:(SKPaymentTransaction *)transaction
{
    [self recordTransaction:transaction];
    [self provideContent:transaction.originalTransaction.payment.productIdentifier];
    [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}

- (void)recordTransaction:(SKPaymentTransaction *)transaction
{
    NSLog(@"Record Transaction...");
    // ToDo: Implement 'recordTransaction'.
}

- (void)provideContent:(NSString *)productIdentifier
{
    NSLog(@"Provide Content");
    // ToDo: Implement 'provideContent'.
}

在不同的机器上测试了相同的代码。它可以在我的开发机器上正常工作。看起来这不是我的准则。
