ios - なぜこの Objective-C コードは False Purchase Tracking をトリガーするのですか?

Question

このコードのポイントは、MobileAppTracking と呼ばれるサービスを使用して購入を追跡することです。その一部は正しく追跡されます。しかし、このサービスは、このコードが余分な購入の呼び出しを大量に送信していることを示しており、iTunes Connect には記録がありません。以下のほとんどは、典型的な IOS ストアキットのボイラープレート コードです。具体的には、このコードは、IOS 購入用の IOS プラグインである InAppPurchaseManager からのものです。

私が使用しているプラ​​グインは次のとおりです: https://github.com/phonegap/phonegap-plugins/tree/master/iPhone/InAppPurchaseManager

そして、ここに私の変更されたコードがあります:

// SKPaymentTransactionObserver methods
// called when the transaction status is updated
//
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
    NSString *state, *error, *transactionIdentifier, *transactionReceipt, *productId;
    NSInteger errorCode;
    SKPayment *thePayment;

    for (SKPaymentTransaction *transaction in transactions)
    {
        error = state = transactionIdentifier = transactionReceipt = productId = @"";
        errorCode = 0;

        BOOL shouldTrackEvent = false;  //  maybe this should just be for successful purchases.

        switch (transaction.transactionState)
        {
            case SKPaymentTransactionStatePurchasing:
                continue;

            case SKPaymentTransactionStatePurchased:
                state = @"PaymentTransactionStatePurchased";
                transactionIdentifier = transaction.transactionIdentifier;
                transactionReceipt = [[transaction transactionReceipt] base64EncodedString];
                productId = transaction.payment.productIdentifier;
                //thePayment = transaction.payment;

                //NSLog(@"localCurr=", thePayment.currency );
                //NSLog(@"localCurr=", thePayment.localizedTitle );
                shouldTrackEvent = true;
                break;

            case SKPaymentTransactionStateFailed:
                state = @"PaymentTransactionStateFailed";
                error = transaction.error.localizedDescription;
                errorCode = transaction.error.code;
                NSLog(@"error %d %@", errorCode, error);

                break;

            case SKPaymentTransactionStateRestored:
                state = @"PaymentTransactionStateRestored";
