ios - iOS In-App Purchase invalid product ID iOS 5.1.1

Question

In-App purchase retrieving products data and purchasing are working well on iOS 6. However, on iOS 5.1.1, I receive "invalid product identifier" when trying getting a product data. What can be incompatible here?

Answer 1

这是 Apple 托管的内容吗？如果是这样，Apple 的托管内容仅适用于 iOS 6 及更高版本。
