iOS - 获取应用内订阅购买的到期时间 [英] iOS - Getting expiration time of in-app subscription purchases

问题描述

在我的iOS应用中，我提供了应用内购买订阅。为了使用该应用程序，他们必须购买订阅，然后才能使用。

In my iOS app, I included in-app purchase for subscription. In order to use the app, they have to purchase the subscription and then only it will work.

我没有任何服务器，所以我将保留所有应用程序中的数据，如收据，产品详细信息等。

I don't have any server and so I'll maintain all the data with in the app, like receipts, product details etc.

首次购买订阅后，我会立即发送验证收据请求。在该收据中，我正在提取expires_date值（自1970年以来以毫秒为单位）并将其转换为日期并将其存储在 NSUSerDefaults 中。

First time after purchasing the subscription, immediately, I'll send request for validation receipt. In that receipt, I'm extracting the "expires_date" value (which is in milliseconds since 1970) and converting it to date and storing it in NSUSerDefaults.

我将过期日期作为我检查时的相同日期。不知道沙箱是否会发送短期日期用于测试目的，或者沙盒服务器是否仅为续订订阅发送过期日期。

I'm getting the expired date as same date when I'm checking it. Don't know whether sandbox will send short duration date for testing purposes or will sandbox server sends expires-date only for renewed subscriptions.

如何识别到期日期？

推荐答案

沙箱应该按照以下方案返回到期日期。

The sandbox is supposed to return expiration dates in the following scheme.
