Question

我有两个问题：

购买订阅后，我收到＆＃34; 您已全部设置您的购买成功＆＃34;但在SKPaymentTransactionObserver paymentQueue:updatedTransactions:中，我收到SKPaymentTransactionStateFailed状态"Cannot connect to iTunes Store"错误。
某次购买开始时，我会收到确认购买，但是paymentQueue:updatedTransactions:也会被调出失败状态

注意：我在使用网络链接调节器的模拟器上进行测试（HighLatencyDNS自定义配置文件500毫秒）

此外，我在DNS延迟超过0.5秒的网络中也注意到了这个问题

将付款添加到队列：

- (BOOL)internalBeginPurchaseFor:(NSString *)productId
{
    if ([SKPaymentQueue canMakePayments]) {
        SKProduct *product;
        if ((product = self.products[productId])) {
            SKPayment *payment = [SKPayment paymentWithProduct:product];
            [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
            [[SKPaymentQueue defaultQueue] addPayment:payment];
            return YES;
        }
    }
    return NO;
}

处理交易状态：

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions
{

    for (SKPaymentTransaction *transaction in transactions)
    {
        NSString *transactionIdentifier = transaction.transactionIdentifier;
        NSString *transactionDetails = @"";

        switch (transaction.transactionState) {
            case SKPaymentTransactionStatePurchasing:
                NSLog(@"User is purchasing");
                transactionDetails = @"User purchasing";
                break;

            case SKPaymentTransactionStatePurchased: 
                NSLog(@"User purchased");
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                [self executeHandlerForTransaction:transaction andSuccessFlag:YES];
                transactionDetails = @"User purchased";
                break;

            case SKPaymentTransactionStateFailed:
                NSLog(@"failed to purchase");
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                [self executeHandlerForTransaction:transaction andSuccessFlag:NO];
                transactionDetails = @"Failed to purchase";
                break;

            case SKPaymentTransactionStateRestored:
                NSLog(@"restored transaction");
                transactionDetails = @"Restored transaction";
                break;

            case SKPaymentTransactionStateDeferred:
                NSLog(@"pending for transaction");
                transactionDetails = @"Pending for transaction";
                break;
        }

        NSString *stringData = [NSString stringWithFormat:@"%@ for transaction Identifier %@",transactionDetails, transactionIdentifier];
        [EventLogger logEventOfType:PURCHASE_PLAN withData:stringData andNotes:@"APIAPurchase"];

    }
}

有什么建议吗？
