ios - restoreCompletedTransactions 在 xcode 8 swift 3 中不起作用

Question

我在 AppStore 上有应用程序，恢复购买工作正常（构建是使用 Swift 2.2 完成的）。但是，我刚刚切换到 Swift 3 和 xCode 8，restoreCompletedTransactions 停止工作。未调用 paymentQueue 并且 paymentQueueRestoreCompletedTransactionsFinished 在 iTuneStore 上为真正的 appleId 用户返回队列中的 0 个事务。但是，当我切换到沙盒测试帐户时，它可以工作（即使在 Swift 3 中）。这是代码...有谁知道xCode 8中是否对此有一些更改？

func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction])
{
    for transaction in transactions {

        switch transaction.transactionState {
        case SKPaymentTransactionState.purchased:
            NSLog("Transaction completed successfully.")
            SKPaymentQueue.default().finishTransaction(transaction)
            transactionInProgress = false
            if (self.selectedProductIndex != -1)
            {
                delegate.didBuyTraining()
            }
            break


        case SKPaymentTransactionState.failed:
            NSLog("Transaction Failed");
            SKPaymentQueue.default().finishTransaction(transaction)
            transactionInProgress = false
            break

        case SKPaymentTransactionState.restored:
            NSLog("Transaction completed successfully.")
            SKPaymentQueue.default().finishTransaction(transaction)
            transactionInProgress = false
            break

        default:
            NSLog(String(transaction.transactionState.rawValue))
            break
        }
    }
}

func paymentQueueRestoreCompletedTransactionsFinished(_ queue: SKPaymentQueue!) {
    var productIds = [String]()
    let count = queue.transactions.count
        for var transaction in queue.transactions{
        let prodID = transaction.payment.productIdentifier 
        productIds.append(prodID)
    }
    for var prodID in productIds {
        for var prod in productsArray {
            if prod?.productIdentifier == prodID{
                set_defaults((prod?.localizedTitle)!)
            }
        }
    }
}
