swift – SKPaymentQueue没有为自动续订订阅产品完成SKPaymentTr

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
            }
        }
    }
}

如上所述,在paymentQueue：updatedTransactions：方法中,调用queue.finishTransaction(事务).通常情况下,交易已完成,不再停留.

但是,当我再次运行该应用程序时,该交易仍未完成.顺便说一句,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,通过调用paymentQueue：updatedTransactions：开始处理剩余的事务.这不像我的期望.

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看法吗？有没有SKPaymentQueue.defaultQueue().finishTransaction(交易)没有完成交易的情况？
