发现iOS应用程序购买日期 [英] Discovering the iOS App Purchase Date

问题描述

我明确没有提到应用内购买。

I'm explicitly NOT referring to in-app purchases.

是否有可能在iOS上发现应用程序本身的购买日期？

Is it possible to discover the purchase date of the application itself on iOS?

我想奖励早期购买者。奖励早期用户（推出该应用的用户）不的方式。我想奖励那些在1月1日到1月31日之间购买游戏的人，甚至是2月28日首次推出游戏的客户。

I'd like to reward early purchasers. Rewarding early users (those who launched the app) is not the way to go. I'd like to reward people who bought the game, for example, between Jan 1st and Jan 31st, even the portion of customers who who made the first launch on Feb 28th.

想法？

推荐答案

只是为了更新它，它是可能的。看一下这个问题的答案 - 收据中的一个字段是原始购买日期。还有来自WWDC13的视频/演示文稿讨论了这一点 - 使用收据保护您的数字销售

just to update this, it IS possible. Take a look at the answer to this question -- one of the fields in the receipt is "original purchase date". There is also a video/presentation from WWDC13 that discusses this - "Using Receipts to Protect Your Digital Sales"
