How can I detect this situation in code:

  • User purchase a full version with in-app purchase.

  • User delete the application from iPhone.

  • User installed the application again

  • User purchases full version,

My problem is that in testing, I can see a message box saying “you already purchased…”, but in the application updateTransactions not called.

In this situation I need to change to full version. How can I detect this event?
I.e., How can I know in my application that the user already purchased so I will “open” to full version?

Thanks.

    Use [[SKPaymentQueue defaultQueue] restoreCompletedTransactions]. It will force your app to receive transactions again.
