SKPaymentTransactionObserver没有在应用程式切换回应 [英] SKPaymentTransactionObserver not getting a callback on app switch

问题描述

我设置了应用内购买，以便在用户点击购买按钮时，会显示请稍候视图，并将付款添加到付款队列中。这总是导致队列的观察者的立即回调，说交易进入采购状态。

I have in-app purchases set up so that when a user clicks on the buy button, a "Please Wait" view appears and adds a payment to the payment queue. This always causes an immediate callback of the queue's observer saying that the transaction entered the "Purchasing" state.

当用户在确认之前返回主屏幕时，要购买对话框弹出，然后取消。如果我在主屏幕上等待一段时间，然后切换回应用程序，则应用程序不会获得有关事务切换状态或被删除的任何回调。如果我检查支付队列，我可以看到，交易仍在队列中，仍然处于采购状态。在恢复应用程序后，有什么我可以做的，让它回调并将其从队列中删除？

My problem happens when the user returns to the main screen before the confirm to purchase dialog pops up, then cancels. If I wait around on the main screen awhile before switching back to the application, the application never gets any callback about the transaction switching state or being removed. If I examine the payment queue, I can see that the transaction is still in the queue, still in the "Purchasing" state. Is there anything I can do to make it call back and remove it from the queue after resuming the application?

推荐答案

您的情况正确，您遇到了此问题：

If I understood your situation correctly, you've encountered this problem:

在应用程序购买用户取消tx，而应用程序在后台：tx状态保持购买

这似乎是苹果商店套件中的一个错误。如果您在启动购买后立即将应用程序发送到后台，然后在提示购买确认弹出窗口时按取消按钮，则可以轻松地重现此问题。您的应用程式永远不会收到交易失败（已取消）的通知，并会进入封锁状态（如果您在购买完成后停用使用者介面，无法与使用者互动）。

This appears to be a bug in Apple's Store kit. The issue can easily be reproduced if you send your app to background right after initiating a purchase and then pressing the cancel button when the buy confirmation popup is prompted. Your app will never receive the transaction failed(cancelled) notification and will enter a blocked state (if you disabled the UI trying to prevent the user from interacting with the app until the purchase has finished).

我们必须等待苹果的修复。在此期间，如果您的应用程式进入封锁状态，因为您在购物时停用了使用者介面;您应该实现一些允许用户离开该状态的机制。

We have to wait for a fix from Apple. In the meantime, if your app is entering a blocked state because you disable UI while making a purchase; you should implement some mechanism to allow the user to leave that state.

祝你好运！
