swift - SKPaymentQueue 未完成自动续订订阅产品的 SKPaymentTransaction

Question

我正在尝试实现自动续订产品。问题是 SKPaymentQueue 无法通过调用 SKPaymentQueue.defaultQueue().finishTransaction(transaction) 完成 SKPaymentTransaction。

func paymentQueue(queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
    if let transactions = transactions as? [SKPaymentTransaction] {
        for transaction in transactions {
            switch transaction.transactionState {
            case .Purchasing:
                break
            case .Purchased:
                queue.finishTransaction(transaction) // finish transaction
                self.purchasedWithTranasction(transaction)
            case .Failed:
                queue.finishTransaction(transaction) // finish transaction
                self.failedWithTransaction(transaction)
            case .Restored:
                queue.finishTransaction(transaction) // finish transaction
                self.restoredWithTransaction(transaction)
            case .Deferred:
                queue.finishTransaction(transaction) // finish transaction
            }
        }
    }
}

如上，在paymentQueue:updatedTransactions:方法中，调用了queue.finishTransaction(transaction)。一般情况下，交易结束，不会再停留。

但是当我再次运行该应用程序时，交易仍未完成。顺便说一下，我在 AppDelegate 中设置了事务观察器，如下所示。因此，当应用程序启动时，剩余的交易开始通过调用 paymentQueue:updatedTransactions: 进行处理。这和我的预期不一样。

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // add transaction observer
    SKPaymentQueue.defaultQueue().addTransactionObserver(CargoBay.sharedManager())

    ....

    return true
}

你们对这个问题有什么想法吗？是否存在 SKPaymentQueue.defaultQueue().finishTransaction(transaction) 未完成交易的情况？

Answer 1

是否有可能您没有再次看到相同的交易，而是来自 iTunes 沙盒的新自动续订交易？

在 iTunes 沙盒中测试自动续订订阅时，他们人为地加快了续订速度。这会导致每隔几分钟出现一个新事务。
