SKPaymentQueue updatedTransactions未被調用

Question

我得到“這個應用程序購買已經被購買它將免費恢復”但代表updatedTransactions沒有被調用，沒有任何反應，IAP沒有執行。

我已經實現了恢復購買，它工作正常，但我如何阻止用戶再次購買非消耗品？為什么沒有調用委托updatedTransactions（SKPaymentTransactionState.Restored）？

即使在刪除並重新安裝應用程序后進行購買也會顯示此彈出窗口。

這是我的代碼。如果我做錯了，請告訴我。謝謝

func makePaymentForProduct(product:SKProduct){
    let payment = SKPayment.init(product: product)
    SKPaymentQueue.defaultQueue().addPayment(payment)
    SKPaymentQueue.defaultQueue().addTransactionObserver(self)
}

func restorePurchases(){
    SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
    SKPaymentQueue.defaultQueue().addTransactionObserver(self)
}


//MARK: SKProductsRequestDelegate

func productsRequest(request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
    self.delegate?.didGetProducts(response.products)
}

func request(request: SKRequest, didFailWithError error: NSError) {
    self.delegate?.purchaseFailed(error.localizedDescription)
}

//MARK: SKPaymentTransactionObserver

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

    for (_, transaction) in transactions.enumerate() {
        switch (transaction.transactionState) {
        case SKPaymentTransactionState.Purchased:
            self.completeTransaction(transaction)
            break
        case SKPaymentTransactionState.Restored:
            self.restoreTransaction(transaction)
            break
        case SKPaymentTransactionState.Failed:
            self.failedTransaction(transaction)
            break
        default:
            break
        }
    }
}

func completeTransaction(transaction:SKPaymentTransaction){
    self.delegate?.purchaseSuccessful()
    SKPaymentQueue.defaultQueue().finishTransaction(transaction)
}

func restoreTransaction(transaction:SKPaymentTransaction){
    self.delegate?.purchaseSuccessful()
    SKPaymentQueue.defaultQueue().finishTransaction(transaction)
}

func failedTransaction(transaction:SKPaymentTransaction){
    self.delegate?.purchaseFailed("")
    SKPaymentQueue.defaultQueue().finishTransaction(transaction)
}


//Restore Purchase

func paymentQueueRestoreCompletedTransactionsFinished(queue: SKPaymentQueue) {
    self.delegate?.purchaseRestored()
}

func paymentQueue(queue: SKPaymentQueue, restoreCompletedTransactionsFailedWithError error: NSError) {
    self.delegate?.purchaseFailed(error.localizedDescription)
}

您在調用.restoreCompletedTransactions() 之后設置事務觀察器可能是問題 - 我建議您嘗試

func restorePurchases(){
    SKPaymentQueue.defaultQueue().addTransactionObserver(self)
    SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
}

而不是你上面的實現。

作為旁注，我看到您的原始代碼是在多個位置添加事務觀察器 - 您可能會考慮嘗試將其減少到一個位置（如果可能！）。
