恢复自动续订订阅的订阅购买

Question

当我在我的应用程序中购买以前购买的"Auto-Renewable Subscriptions"时,它说

You're currently subscribed to this...

当我点击OK时,在支付队列的代表中..

- (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]; // Why this is called?
                break;
            case SKPaymentTransactionStateRestored:
                [self restoreTransaction:transaction];
            default:
                break;
        }
    }
}

返回的transaction.transactionState是SKPaymentTransactionStateFailed 而不是SKPaymentTransactionStateRestored,这是正常的吗？

那我该如何正确处理呢？

我有同样的问题，我认为没有任何方法可以区分此事件与其他错误（它返回错误代码SKErrorPaymentCancelled）。我认为处理它的唯一方法是使用“恢复购买”按钮，并[[SKPaymentQueue defaultQueue] restoreCompletedTransactions]在用户按下它时调用。
