Answer 1

The StoreKit framework allows you to restore purchases for users without having to pay multiple times for a purchase.

Look at the Store Kit documentation for Restoring Transactions.

The restoration process requires the user to log in with their iTunes Account, so that the system knows their purchase history.

As long as you implement the restore process and provide a UI for a user to do so, you users should never have to pay more than once for a purchase within your app, even if they uninstall the app and reinstall it on a different device.
