- (void)recordTransaction:(SKPaymentTransaction *)transaction {
    if ([transaction.payment.productIdentifier isEqualToString:[self getProductId:gFullVersion]]) {
        // save the transaction receipt to disk
        [[NSUserDefaults standardUserDefaults] setValue:transaction.transactionReceipt forKey:[self getProductId:gFullVersion]];
        [[NSUserDefaults standardUserDefaults] synchronize];
    }
}

[NSData dataWithContentsOfURL:[[NSBundle mainBundle] appStoreReceiptURL]]

// saves a record of the transaction by storing the receipt to disk
- (void)recordTransaction:(SKPaymentTransaction *)transaction {
    if ([transaction.payment.productIdentifier isEqualToString:[self getProductId:gFullVersion]]) {
        // save the transaction receipt to disk
        [[NSUserDefaults standardUserDefaults] setValue:[NSData dataWithContentsOfURL:[[NSBundle mainBundle] appStoreReceiptURL]] forKey:[self getProductId:gFullVersion]];
        [[NSUserDefaults standardUserDefaults] synchronize];
    }
