updatedTransactions:委托回调使用几天前的旧事务触发。我试着在它们上调用finishTransactions，但是当我启动应用程序时，相同的交易仍然存在（检查了transactionIdentifier）一遍又一遍。
我不能再买新东西了。当进行新的购买时，其中一个旧交易将以SKPaymentTransactionStatePurchased状态返回，但因为它之前已经成功，所以我从Apple收到一个错误：* “此应用内购买已被购买。它将免费恢复。【环境：沙盒]"*

如何从事务队列中正确删除事务？

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions {

    // Getting called with old, already finished transactions

    for (SKPaymentTransaction *transaction in transactions) {
        switch (transaction.transactionState) {
            case SKPaymentTransactionStatePurchasing:
                break;
            case SKPaymentTransactionStateDeferred:
                // ...
                break;
            case SKPaymentTransactionStateFailed:
                // ...
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
            case SKPaymentTransactionStatePurchased:
                // validate receipt first
                // then finish transaction
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
            case SKPaymentTransactionStateRestored:
                // ...
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
            default:
                break;
        }
    }
}

我确认了finishTransactions没有将它们从队列中删除。

NSArray<SKPaymentTransaction *> *transactions = [[SKPaymentQueue defaultQueue] transactions];
NSLog(@"BEFORE transactions = %@", transactions);
for (SKPaymentTransaction *txn in transactions) {
    [[SKPaymentQueue defaultQueue] finishTransaction:txn];
}
transactions = [[SKPaymentQueue defaultQueue] transactions];
NSLog(@"AFTER transactions = %@", transactions);

输出：

BEFORE transactions = (
    "<SKPaymentTransaction: 0x2802c8b10>",
    "<SKPaymentTransaction: 0x2802c8c60>",
    "<SKPaymentTransaction: 0x2802c8c40>",
    "<SKPaymentTransaction: 0x2802c8c20>",
    "<SKPaymentTransaction: 0x2802c8b00>"
)
AFTER transactions = (
    "<SKPaymentTransaction: 0x2802c8b10>",
    "<SKPaymentTransaction: 0x2802c8c60>",
    "<SKPaymentTransaction: 0x2802c8c40>",
    "<SKPaymentTransaction: 0x2802c8c20>",
    "<SKPaymentTransaction: 0x2802c8b00>"
)

我在苹果开发者论坛上发现，这在过去48小时内影响了其他一些人。我认为这是苹果方面的一个问题。
