使用Google Analytics iOS SDK进行应用内购买跟踪

Question

我想按照其电子商务跟踪指南中的说明,使用Google Analytics SDK for iOS v2跟踪应用内购买情况.

我在收到SKPaymentTransactionStatePurchased事务更新后正在执行以下操作:

- (void) trackTransaction:(SKPaymentTransaction*)transaction
{
    NSString *transactionIdentifier = transaction.transactionIdentifier;
    GAITransaction *gaiTransaction = [GAITransaction transactionWithId:transactionIdentifier withAffiliation:@"App Store"];

    SKPayment *payment = transaction.payment;
    NSString *productIdentifier = payment.productIdentifier;
    SKProduct *product = [self productForIdentifier:productIdentifier];
    NSString *productTitle = product.localizedTitle;
    int64_t priceInMicros = product.price.floatValue * 1000000; // FIXME: Doesn't consider different currencies
    [gaiTransaction addItemWithCode:productIdentifier name:productTitle category:nil priceMicros:priceInMicros quantity:payment.quantity];

    gaiTransaction.revenueMicros = priceInMicros * payment.quantity; // FIXME: doesn't consider Apple's cut

    id<GAITracker> tracker = [GAI sharedInstance].defaultTracker;
    [tracker trackTransaction:gaiTransaction];
}

以上是跟踪应用内购买的正确方法吗？我至少发现了两个问题:

1. SKProduct返回本地化价格,如果我跟踪它,收入汇总将是不正确的.有没有办法规范价格？
2. 退回的收入并没有考虑Apple的削减,这并不总是30%.是否有可能获得应用程序内的净收入？

SKProduct返回本地化价格,如果我跟踪它,收入汇总将是不正确的.有没有办法规范价格？

Google Analytics SKD for iOS v3增加了对货币的支持.跟踪事务如下所示:

- (void)storePaymentTransactionFinished:(NSNotification *)notification
{
    SKPaymentTransaction *paymentTransaction = notification.transaction;
    if (paymentTransaction.transactionState == SKPaymentTransactionStateRestored) return;

    SKPayment *payment = paymentTransaction.payment;
    NSString *sku = payment.productIdentifier;
    SKProduct *product = [[RMStore defaultStore] productForIdentifier:sku];
    NSLocale *priceLocale = product.priceLocale;
    NSString *currencyCode = [priceLocale objectForKey:NSLocaleCurrencyCode];
    NSString *transactionId = paymentTransaction.transactionIdentifier;
    NSNumber *productPrice = product.price;
    {
        NSNumber *revenue = @(productPrice.floatValue * payment.quantity);
        GAIDictionaryBuilder *builder = [GAIDictionaryBuilder createTransactionWithId:transactionId
                                                                          affiliation:@"App Store"
                                                                              revenue:revenue
                                                                                  tax:0
                                                                             shipping:0
                                                                         currencyCode:currencyCode];
        NSDictionary *parameters = [builder build];
        [_tracker send:parameters];
    }
    {
        GAIDictionaryBuilder *builder = [GAIDictionaryBuilder createItemWithTransactionId:transactionId
                                                                                     name:product.localizedTitle
                                                                                      sku:sku
                                                                                 category:@"In-App Purchase"
                                                                                    price:productPrice
                                                                                 quantity:@(payment.quantity)
                                                                             currencyCode:currencyCode];
        NSDictionary *parameters = [builder build];
        [_tracker send:parameters];
    }
}

上面的代码使用RMStore来方便.

退回的收入并没有考虑Apple的削减,这并不总是30%.是否有可能获得应用程序内的净收入？

没有.
