Saving Address Book References to a File

Question

In my app, I have built a speed dial-like view very similar to the Phone.app's Favorites list. The user can add new contacts and select which number to call, but I am having issues storing the info to a file so that it can be reloaded after the app is relaunched.
Right now, I have created a wrapper class that stores the ABRecord's unique ID as well as the phone number's ID, but it won't archive to a file. Any thoughts? Should I just use a NSMutableArray with an NSMutableDictionary storing these values instead of the wrapper class?

Answer 1

You should get the ABRecordID of the contact and store that:
ABRecordID personID = ABRecordGetRecordID(person);
When needed use the AddressBook api to retrieve the actual record:
ABAddressBookRef addressBook = ABAddressBookCreate();
ABRecordRef abPerson = ABAddressBookGetPersonWithRecordID(addressBook, abPersonID);
