ABAddressBookCreate() , ABAddressBookGetGroupCount , ... return @"0x00000000 <nil>"?

Question

I'm trying to get Groups Name but after many time call this method "by the user to reload contacts" it give the nil value and the following error.

-(void) getGroupsName
    {
        [groupsName removeAllObjects];
        //address book object to interact with iPhone contacts.
        ABAddressBookRef addressbook = ABAddressBookCreate();
        //get groups count
        CFIndex groupsCount          = ABAddressBookGetGroupCount(addressbook);
        //get all available groups as array
        CFArrayRef allGroups         = ABAddressBookCopyArrayOfAllGroups(addressbook);

        for (int i = 0; i<groupsCount; i++) {
            //get group of index=i from groups array
            ABRecordRef group = CFArrayGetValueAtIndex(allGroups, i);
            //get group name, I use __bridge_transfer to transfer from C to objective-c.
            [groupsName addObject:(__bridge_transfer NSString*)ABRecordCopyCompositeName(group)];

        }
        CFRelease(allGroups);
        CFRelease(addressbook);
    }

ABAddressBookCreate has been decprecated in iOS6. Use ABAddressBookCreateWithOptions, it will return a CFErrorRef object if you don't have access to the address book.
