ios - [NSBundle appStoreReceiptURL] 的收据在应用程序更新后是否仍然存在

Question

在生产环境中，如果用户进行应用内购买，然后更新到更新版本的应用，反射(reflect)应用内购买的收据是否仍然存在于 bundle 中？还是会被应用更新清除？

Answer 1

好吧，我想我终于找到了这个问题的答案。

A receipt is meant to be a trusted record of a purchase, along withany in-app purchases that the user has made — much like a paperreceipt that you get when shopping in a store. Here are some keypoints about receipts:

• A receipt is created and signed by Apple through the App Store.

• A receipt is issued for a specific version of an application and a specific device.

• A receipt is stored locally on the device.

• A receipt is issued each time an installation or an updateoccurs.

• When an application is installed, a receipt that matches theapplication and the device is issued.

• When an application is updated, a receipt that matches the new version of the application is issued.

• A receipt is issued each time a transaction occurs:

• When an in-app purchase occurs, a receipt is issued so that it can be accessed to verify that purchase.

• When previous transactions are restored, a receipt is issued so that it can be accessed to verify those purchases.

因此，如果您更新收据上有购买历史记录的应用程序，则此购买历史记录应包含在为新应用程序版本签发的新收据中。 (当然除非它是消耗品)。
