我已经多次阅读文档，但仍然不确定如何去做。来自 In App Purchase Programming guide - Restore Purchased Product:
In most cases, all your app needs to do is refresh its receipt and deliver the products in its receipt. The refreshed receipt contains a record of the user’s purchases in this app, on this device or any other device. However, some apps need to take an alternate approach for one of the following reasons:
If you use Apple-hosted content, restoring completed transactions gives your app the transaction objects it uses to download the content.
这是否意味着如果我使用 Apple 托管的内容，我不需要刷新其收据并直接调用restore completed transaction 来检索我以前的下载产品？
最佳答案
你仍然需要这样做。
你引用的文字意思是收据包含用户购买了哪些应用内商品的信息，但收据不包含内容。
因此，如果您使用 Apple 托管的内容，则需要一种机制来下载所述内容。刷新收据时不会提供该内容。但是，当您使用各种恢复功能时，它会被下载。
