AdressBook Listener

Question

I am doing one application which should notify me changes (like update , delete, etc) in contacts of addressbook ie ABAddressBook is used to get all the address contacts. I read that ABAddressBookRegisterExternalChangeCallback will give notifications, but I am not sure how it will work. I wanted to store changes even though my application is closed. Let me know anybody has worked upon same or any inputs.

Answer 1

You will only get a callback when you run your application. It's not possible to get a notification when the application is not running.
