我的产品列表中同时包含“非消耗性”和“自动更新”订阅。因此，当我尝试恢复购买时，我会完成所有购买。现在，恢复购买时应该采取什么方法。
就我而言，我有两种产品分别按月和按年收费，而另一种则是非消耗性产品，可以终身使用。因此，在测试期间，我进行了几笔交易。但是在恢复时，我注意到我得到了所有购买的交易清单，需要从中恢复该用户的有效产品。那么我怎么知道要还原哪个项目？
从文档中，我找到了一种验证订阅和产品的方法。但是从我的答复中我可以看到，我拥有每月和终身有效的产品，可以还原。我应该在这里做什么？
这是我的代码
@IBAction func restoreButtonPressed(_ sender: Any) {
// SubscriptionService.shared.restorePurchases()
if self.premium != nil {
// contact alert
self.showActionSheet(title: "Contact us", message: "Tell us your query at \(Settings.requestEmail)", email: Settings.requestEmail)

hud.show(in: self.view)
// let appleValidator = AppleReceiptValidator(service: .sandbox, sharedSecret: Payment.sharedSecret)

答案 0 :(得分：0)
您应检查按最新排序的活动订阅，如果活动订阅处于活动状态，则将其解锁。 这取决于您的订阅逻辑。
就我而言，我检查以下订单。
a）如果购买了终身计划，则该计划将被解锁 一生。
b）如果没有终身购买，则将在 对购买清单进行排序，找出是否有任何有效的订阅 对其进行解锁。
此外，我检查是否有未完成的购买，然后解锁内容并在解锁后将其标记为完成。
