ios - 关于在应用商店处理 iAP 成功的问题

Question

如果用户之前没有付款信息，当 iAP 流程启动时，应用程序会将用户重定向到应用程序商店，以获取用户填写的付款信息，当用户已经完成付款信息时，付款完成(获取提醒购买)成功)资金被切断，应用程序商店没有将用户重定向回应用程序，如果用户返回到应用程序，则会发生通知。

SKPaymentTransactionObserver 没有调用，用户没有获得任何消耗品(应用程序中的信用)

func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
for transaction in transactions {
  switch transaction.transactionState {
  case .deferred:
    print("transactionState = deferred")
  case .purchasing:
    print("transactionState = purchasing")
  case .purchased:
    print("transactionState = purchased")
    SKPaymentQueue.default().finishTransaction(transaction)
    SKPaymentQueue.default().remove(self)
    var receiptBase: String = ""
    if let receiptURL = Bundle.main.appStoreReceiptURL {
      do {
        let receipt = try Data(contentsOf: receiptURL)
        let base64encodedReceipt = receipt.base64EncodedString()
        receiptBase = base64encodedReceipt
      } catch {
        receiptBase = ""
      }
    }
    //call api for add consumable to user
    buyCreditDelegate?.purchasedCredit(transactionId: transaction.transactionIdentifier ?? "", receiptId: receiptBase)
  case .failed:
    SKPaymentQueue.default().finishTransaction(transaction)
    SKPaymentQueue.default().remove(self)
    if let delegate = self.buyCreditDelegate {
      delegate.cancelPurchases()
    }
  case .restored:
    print("transactionState = restored")
}

仅供引用: 我的 iAP 是消耗品。

我该如何解决这个问题，抱歉我的英语不好

Answer 1

删除此行:

SKPaymentQueue.default().remove(self)

您需要您的观察者成为像应用程序委托(delegate)一样永久的持久对象。切勿将其移除，否则商店无法与您交谈。
