如何从恢复的交易中获取产品标识符？

我已成功恢复应用内交易并从原始交易中获取交易标识符，但如何识别交易中购买的产品？是否可以获取之前购买的应用内商品的商品标识符？

如果您的意思是您想检查已经用户购买的已购买商品..是的，您可以这样做

- (void) checkPurchasedItems {
    [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
} //You Call This Function

//Then this delegate Function Will be fired
- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue {
    purchasedItemIDs = [[NSMutableArray alloc] init];

    NSLog(@"received restored transactions: %i", queue.transactions.count);
    for (SKPaymentTransaction *transaction in queue.transactions) {
        NSString *productID = transaction.payment.productIdentifier;
        [purchasedItemIDs addObject:productID];
    }
}

if you mean you want to check the purchased items that already user buy it .. yes you can do like this

- (void) checkPurchasedItems {
    [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
} //You Call This Function

//Then this delegate Function Will be fired
- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue {
    purchasedItemIDs = [[NSMutableArray alloc] init];

    NSLog(@"received restored transactions: %i", queue.transactions.count);
    for (SKPaymentTransaction *transaction in queue.transactions) {
        NSString *productID = transaction.payment.productIdentifier;
        [purchasedItemIDs addObject:productID];
    }
}

SWIFT 版本：

一旦您获得委托

func paymentQueueRestoreCompletedTransactionsFinished(queue: SKPaymentQueue!) {
    var productIds = [String]()
    for transcation in queue.transactions{
        if let productID = transcation.payment?.productIdentifier{
        productIds.append(productID)
        }
    }

SWIFT VERSION:

Once you get the delegate

func paymentQueueRestoreCompletedTransactionsFinished(queue: SKPaymentQueue!) {
    var productIds = [String]()
    for transcation in queue.transactions{
        if let productID = transcation.payment?.productIdentifier{
        productIds.append(productID)
        }
    }
