Hello,
I have a big problem...
I first proposed a paid application on the Apple Store. Then, I realized
that offering it as a freemium would be more efficient (offering a free
version and then proposing a full version as an in-App).
The problem is "how do I know if the user has already bought the initial full version from the store)?
It seems that QtPurchasing can only handle In-Apps but can't tell if the application itself has been purchased...
How to do it ?
Thanks !
