iOS IAP还原不起作用 [英] iOS IAP restore doesn't work

问题描述

我有带有IAP的ios应用.我以测试人员的身份在沙箱中购买产品，一切正常.我收到收据并把它切丁.然后，我重新安装该应用程序，我正在尝试还原IAP并致电

I have the ios App with IAP. I buy product in sandbox as tester user and everything is Ok. I receive receipt and parce it. Then I re-install the App, I'm trying to restore IAP and call

SKPaymentQueue.defaultQueue().restoreCompletedTransactions()

下一步

paymentQueueRestoreCompletedTransactionsFinished(queue: SKPaymentQueue) 

被调用.什么也没有恢复.我想一定是有

is called. Nothing restored. I suppose there must be call of

paymentQueue(queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction])

但是它不见了！收据也不存在.

but it is missing! The receipt also doesn't exist.

必须要恢复交易(因为如果我再次购买产品，StoreKit说它已经购买了)，我在做什么错了?

There must be transactions to restore (because if I buy product again StoreKit says that it is already purchased) What am I doing wrong?

UPD:

我要还原的产品是不可更新的订阅.如果这是唯一可还原的产品，则Apple不会返回交易清单.如果购买了其他产品(例如，非消耗品)，Apple将返回完整的交易清单...

The product I want to restore is Non-renewable subscription. If this is the only kind of products to restore, Apple does not return transactions list. If there was another product purchased (for example, Non-Consumable) Apple returns full list of transactions...

推荐答案

在恢复购买之前，我要求收据:

I request the receipt before restoring purchases:

let receiptRefreshRequest: SKRequest = SKReceiptRefreshRequest()
receiptRefreshRequest.delegate = self
receiptRefreshRequest.start()

然后响应后我进行恢复

public func requestDidFinish(request: SKRequest) {
    if request == receiptRefreshRequest {
        SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
    }
}
