ios - 如何正确处理 iOS 应用的应用内购买以及如何定义产品？

问题描述

我按照本指南在我的应用中设置了应用内购买。我已经完成了所有工作并在 App Store Connect 中进行了设置。我的问题是目前的实际购买只是 UserDefaults forArePagesUnlocked = true但我在产品中实际定义它的位置时遇到了麻烦。我了解如何设置和管理购买和恢复，但我在哪里实际将产品定义为在购买按钮操作中将 ArePagesUnlocked 的值从 false 更改为 true 的指令？我试过了，但如果没有连接，那么用户仍然解锁了它。我必须单独构建并发送它吗？在我的研究过程中，我一直有点困惑，到目前为止还没有找到一个明确的答案，所以任何帮助都将不胜感激。谢谢你。

编辑：代码：

   public init(productIds: Set<ProductIdentifier>) {
    productIdentifiers = productIds
    for productIdentifier in productIds {
        let purchased = UserDefaults.standard.bool(forKey: productIdentifier) // this i use to see if purchased
        if purchased {
            purchasedProductIdentifiers.insert(productIdentifier)
            print("Previously purchased: \(productIdentifier)")
        } else {
            print("Not purchased: \(productIdentifier)")
        }
    }
    super.init()

    SKPaymentQueue.default().add(self)
}
}

我需要从上面添加一个单独的 UD 值吗？似乎在我重新启动应用程序之前它不知道它已购买，我怎样才能让它即时？

extension IAPHelper: SKPaymentTransactionObserver {

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)
}

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?,
        let localizedDescription = transaction.error?.localizedDescription,
        transactionError.code != SKError.paymentCancelled.rawValue {
        print("Transaction Error: \(localizedDescription)")
    }

    SKPaymentQueue.default().finishTransaction(transaction)
}

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

    purchasedProductIdentifiers.insert(identifier)
    UserDefaults.standard.set(true, forKey: identifier)
    NotificationCenter.default.post(name: .IAPHelperPurchaseNotification, object: identifier)
}
