================================================================================================
|
|
|
|
Interface to the device's In-App Purchase system.
|
|
|
|
|
|
This interface was designed to be dropped into any game that needs support for in-app purchases,
|
|
that is, there is nothing game-specific about this interface or its implementation.
|
|
|
|
It is essentially a singleton implemented in the idInAppPurchase namespace. The singleton must
|
|
be initialized at application launch (via Initialize()) and shut down at application exit (via
|
|
Shutdown()).
|
|
|
|
There are functions to request information about products for sale within the app, check whether
|
|
a particular product has been purchased, and get the localized price for a product, suitable
|
|
for displaying in the user interface.
|
|
|
|
Generally an app should call RequestInformation() at startup (but after Initialize()) and pass
|
|
in all the product identifiers that the app offers for sale. The request will run in the
|
|
background so that the interface will remain responsive. Once the requests have been returned,
|
|
the application can get the price information and actually initiate purchases of products.
