【中文标题】IAP（应用内购买）入门价格我如何管理它 iOS？【英文标题】：IAP(in app purchase) introductory price how can I manage it iOS? 【发布时间】：2018-02-08 07:19:29 【问题描述】：我已经为 ios 成功实现了一组 IAP introductory price，但我很困惑是否需要在 iOS 端使用任何额外的代码来管理它？如果是，需要进行哪些更改？
【问题讨论】：
【参考方案1】：好吧，如果你想正确地实现它，你实际上需要额外的代码。这是为了让客户清楚地了解他得到了什么。
在 iOS 12 和 13 中，您可以获得 3 种不同的订阅介绍价格：
免费试用 现收现付 预付款关于三者的意义以及订阅的简单和整体视图，请参阅Auto-renewable Subscriptions Apple doc with recommended UI
在向您展示购买的视图控制器时，您应该：
-
正确显示优惠：例如：“开始您的 1 个月免费
试用，然后每月 1.99 美元”免费试用介绍价；
处理用户已经从过去的介绍价格中受益的事实，因此宁愿显示“订阅 1.99 美元/月”（到
继续同一个例子）。这需要您查看用户拥有的收据并检查“is_trial_period”或“is_in_intro_offer_period”是否设置为 true（请参阅答案底部的我的代码）。
在我之前提到的 Apple 文档中，有许多“实际”屏幕显示了不同的用例。

【讨论】：
您好，您对我的情况有什么想法吗？我有一个现有的应用程序，其中包含在应用程序商店中的自动更新 IAP。我现在在 iTunes 上添加了介绍性价格，并且正在与沙盒用户进行测试。我在以前的版本中使用该用户全额购买了订阅。但是现在当我检查收据时，对于is_in_intro_offer_period，我得到true。即使我刚刚实施了介绍性优惠，而该用户之前从未购买过介绍性优惠。知道为什么会这样吗？【参考方案2】：
如果您正确实施了 IAP 介绍性价格，您应该不需要在 iOS 端做任何额外的工作来管理它。价格通过 iTunesConnect 界面进行管理。通过正确实现它，我的意思是使用 SKProduct API 来获取价格并将其显示在应用程序中，这样当您从 iTunes 连接更改它时，它也会在应用程序中更改。
