在iOS中为应用内购买设置家庭共享

苹果刚刚发布了应用程序内购买的家庭共享，我正试图通过自动续费订阅将其添加到我的应用程序中

从视频中，他们说一切都应该像魔术一样工作，没有代码更改，但我想对我来说不是这样。即使在家庭成员设备上恢复购买后，也不会发生任何事情

我是否需要任何额外的设置才能正常工作

我在应用程序中实现了如下恢复/购买逻辑：

public func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
    for transaction in transactions {
        switch transaction.transactionState {
            case .purchased:
                complete(transaction: transaction)
                break
            case .failed:
                fail(transaction: transaction)
                break
            case .restored:
                restore(transaction: transaction)
                break
            case .deferred:
                break
            case .purchasing:
                break
        }
    }
}

private func complete(transaction: SKPaymentTransaction) {
    print("complete...")
    deliverPurchaseNotificationFor(identifier: transaction.payment.productIdentifier)
    SKPaymentQueue.default().finishTransaction(transaction)
    promotedPayment = nil
}

private func restore(transaction: SKPaymentTransaction) {
    guard let productIdentifier = transaction.original?.payment.productIdentifier else { return }
    print("restore... \(productIdentifier)")
    deliverPurchaseNotificationFor(identifier: productIdentifier)
    SKPaymentQueue.default().finishTransaction(transaction)
}

private func fail(transaction: SKPaymentTransaction) {
    print("fail...")
    if let transactionError = transaction.error as NSError? {
        if transactionError.code != SKError.paymentCancelled.rawValue {

            let failedString = "Transaction Error: \(String(describing: transaction.error?.localizedDescription ?? ""))"
            print(failedString)

            NotificationCenter.default.post(name: NSNotification.Name(rawValue: IAPHelper.failedNotification), object: failedString)
        }
    }

    NotificationCenter.default.post(name: NSNotification.Name(rawValue: IAPHelper.failedNotification), object: nil)
    SKPaymentQueue.default().finishTransaction(transaction)
    promotedPayment = nil
}

private func deliverPurchaseNotificationFor(identifier: String?) {
    guard let identifier = identifier else { return }

    purchasedProductIdentifiers.insert(identifier)
    UserDefaults.standard.set(true, forKey: identifier)
    UserDefaults.standard.synchronize()
    NotificationCenter.default.post(name: NSNotification.Name(rawValue: IAPHelper.purchaseNotification), object: identifier)
}
