Inapp purchase restoring consumable products

Question

i have uploaded an application which doesnot have webservices, in my application there is an option for user to buy a coin (consumable) using inapp purchases and use these coins to unlock new level. today apple rejected the application and send me following note:

**

Your app uses intermediary currency (coins) to purchase items that function as non-consumable products (unlocking levels) but does not include a restore mechanism. Users restore transactions to maintain access to content that they’ve already purchased.Please modify your app to include an optional user registration feature that allows users to restore their purchases to all of their iOS devices. We recommend indicating that account registration is necessary to restore previously purchased In-App Purchase products, and providing a way for users to register later if they wish to access this content in the future.

**

how can i fix this, as mentioned earlier i dont have a webserver and i cannot use webservices, is there any way around to fix this and get application uploaded.

Answer 1

finally i fixed it by adding login screen in the application and storing user Object in parse.com and when i use inapp purchase i store coins count on Parse and retrieving it on application startup. thanks everyone.
