Address Book callback not called
- by Oliver
I have an iPhone app that makes use of the AddressBook.framework and uses Core Data to store these contacts. In order to make sure I update my own database when the Address Book is updated (whether via MobileMe or editing within my own app), I am subscribing to the notification as to when the Address Book is updating. I call this on startup:
ABAddressBookRef book = ABAddressBookCreate();
ABAddressBookRegisterExternalChangeCallback(book, addressBookChanged, self);
Which (supposedly) calls this on any editing. I have an ABPersonViewController which allows editing, and addressBookChanged never seems to get called.
void addressBookChanged(ABAddressBookRef reference, CFDictionaryRef dictionary, void *context) {
// The contacts controller we need to call
ContactsController *contacts = (ContactsController *)context;
// Sync with the Address Book
[contacts synchronizeWithAddressBook:reference];
}
Is there any reason for it to not be called?
