I have an app that accesses the native address book. With iOS 6, when my app first attempts to access the AB, the user is prompted to allow or deny access; from that point, the user can only change this in the Privacy settings screen.
My app has to behave differently depending on whether or not the user has allowed AB access. Is there any way for my app to receive a notification when the user changes this permission? There is a method in the new API that I can call to determine whether the user has granted AB access or not, but I don't want to have to poll continuously in order to be aware of when this changes.
