ios - 更新后不调用 SKPaymentQueue updatedTransactions 方法

Question

我已经在我的应用中实现了自动续订订阅。一切正常。唯一的问题是方法 public func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) 在自动续订发生后没有被调用，因为它应该根据文档通知我订阅是更新。它仅在我调用 SKPaymentQueue.default().restoreCompletedTransactions()

时调用

我知道它只会自动续订 5 次，而且我必须创建新的沙箱用户并且我尝试了几次。

在我的 AppDelegate 中，我调用了 SKPaymentQueue.default().add(self) 方法。

有什么想法吗？

After a subscription is successfully renewed, StoreKit adds a transaction for the renewal to the transaction queue. Your app checks the transaction queue on launch and handles the renewal the same way as any other transaction. Note that if your app is already running when the subscription renews, the transaction observer is not called; your app finds out about the renewal the next time the app is launched.
