In-App Purchase Tracking

This can be used for In-App Purchase tracking in a specific currency regardless of the local currency that the purchase was paid in. The following example tracks all revenue in EUR. See the In-App Purchase Programming Guide for details on how to implement a method like productForId: that finds an SKProduct by its product identifier.

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {
    for (SKPaymentTransaction *transaction in transactions) {
        switch (transaction.transactionState) {
            case SKPaymentTransactionStatePurchased:
                [self finishTransaction:transaction];

                NSString *productId = transaction.payment.productIdentifier;
                SKProduct *product = [self productForId:productId];
                NSString *currency = [product.priceLocale objectForKey:NSLocaleCurrencyCode];
                NSNumber *price = product.price;

                NSNumber *revenue = [AEPriceMatrix convert:price from:currency to:@"EUR"];
                [self trackRevenue:revenue];

                break;
            // more cases
        }
    }
}
