So richten Sie mit StoreKit 2 einen nicht verbrauchbaren In-App-Kauf in UIKit ein ⇐ IOS

[Guest]

Ich verwende den folgenden Code für einen nicht verbrauchbaren In-App-Kauf in meinen Apps. Hat jemand herausgefunden, wie man damit mit StoreKit 2 und UIKit umgeht? Ich habe mir die Apple-Dokumentation angesehen und den Beispielcode heruntergeladen, sehe aber nicht, wie ich in UIKit dorthin komme.
SKPaymentQueue – veraltet

SKPayment – veraltet

SKProduct – veraltet

transactionState – veraltet

SKPaymentTransaction – veraltet

/>finishTransaction – veraltet

Code: Select all

func paymentQueue(_ queue: SKPaymentQueue, shouldAddStorePayment payment: SKPayment, for product: SKProduct) ->  Bool
{
true
}

func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction])
{
for transaction in transactions
{
switch transaction.transactionState
{
case .purchasing:
break

case .purchased:

SKPaymentQueue.default().finishTransaction(transaction)

// Hide the restore button
navigationItem.setRightBarButton(nil, animated: true)

// Set the ProVerion in the Db to true
IAPHandler.setProVersionToPurchased()

// Also hide the Purchase button
UIView.animate(withDuration: 1.0, animations: { [weak self] in
self?.purchaseBtn_Outlet.alpha = 0
}) { [weak self] (success) in

self?.segControlTop_Constraint.constant = 30

}
