ios - 测试应用内购买(IAP)-需要帮助来清除交易队列

Question

我已经用IAP制作了一个应用程序，并且在我第一次尝试对其进行测试时，我得到了登录提示，但是从那以后，我一直没有收到任何登录提示(我认为这是因为交易失败被卡住了在队列中)。

我非常需要帮助来清除事务队列，因为所有这些IAP语言对我来说都是很陌生的。我已经在几个地方阅读了以下代码段，但老实说我不确定如何正确使用它:

for transaction in SKPaymentQueue.default().transactions {
                guard
                    transaction.transactionState != .purchasing,
                    transaction.transactionState != .deferred
                else {
                    //Optionally provide user feedback for pending or processing transactions
                    return
                }
                //Transaction can now be safely finished
                SKPaymentQueue.default().finishTransaction(transaction)
            }

该代码段终于再次显示了登录提示，但随后我陷入了无休止的登录周期。

下面是我选择放置它的位置，但是它只是让我已经登录后立即再次登录。
(新代码段位于两个注释行之间，标为“NEW”)

func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) { //--------- In App Purchase
        for transaction in transactions{
            //------------------------------------------------------------ New
            for transaction in SKPaymentQueue.default().transactions {
                guard
                    transaction.transactionState != .purchasing,
                    transaction.transactionState != .deferred
                else {
                    //Optionally provide user feedback for pending or processing transactions
                    return
                }
                //Transaction can now be safely finished
                SKPaymentQueue.default().finishTransaction(transaction)
            }
            //------------------------------------------------------------ New
            if transaction.transactionState == .purchased {
                print("Transaction Successful")
                packsUnlocked = true
            } else if transaction.transactionState == .failed {
                print("Transaction Failed with error: \(transaction.error)")
            }
        }

    }

由于Apple支持只能向我提供非技术支持，因此我对此表示任何帮助，并且我已经在此应用程序中投入了大量资源，直到最后一步为止。

谢谢

如果在购买交易后未考虑收据验证，则应在此处进行回调

func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) { //--------- In App Purchase
        for transaction in transactions {
            guard
                transaction.transactionState != .purchasing,
                transaction.transactionState != .deferred
            else {
                //Optionally provide user feedback for pending or processing transactions
                continue
            }

            if transaction.transactionState == .purchased || transaction.transactionState == .restored {
                print("Transaction Successful")
                packsUnlocked = true
            } else if transaction.transactionState == .failed {
                print("Transaction Failed with error: \(transaction.error)")
            }

            //Transaction can now be safely finished
            queue.finishTransaction(transaction)
        }
    }
