我有一个inApp Purchases Client - Sever Model集成的应用程序。
我很难跟踪Restoration and Delivery of the Products.
我正在跟踪UDID购买产品的用户,服务器将产品交付给该特定用户UDID。
Now if i want to restore the previous purchases on a different device,
how will i deliver the content? As my database has a different UDID?
我们必须在什么基础上跟踪购买,以便我们可以在所有设备上交付它???
