title: Consumable In-App Purchase related to App Deletion
body: <p>I've made an iOS app that starts the user with a certain number of an item. The user can buy more of these items via a consumable in-app purchase. The app is not a game so the state of the app does not matter (for example, the level they are on). </p>
  
  <p>What can I do to prevent the user from simply uninstalling the application and receiving the starting number of items (rather than buying more)? I'm storing the items via NSUserDefaults.</p>
