Does an ABAddressBookRef remain valid after the AddressBook that it came from
is released?
Let's say I have a little object that holds onto an address:
@interface AddressInfo : NSObject {
ABRecordID contactRecordID;
ABMultiValueIdentifier addressID;
}
@end
Now let's say I want to open an ABPersonViewController to edit the address.
Can I get the ABAddressBookRef of the person, release the address book and
show the ABPersonViewController (as in Code Sample 1) or does the address book
need hang around (as in Code Sample 2)?
--Code Sample 1--
// self.address is an AddressInfo instance
ABAddressBookRef addressBook = ABAddressBookCreate();
ABPersonViewController *personView = [ABPersonViewController new];
personView.personViewDelegate = self;
personView.displayedPerson =
ABAddressBookGetPersonWithRecordID(addressBook,
self.address.contactRecordID);
personView.displayedProperties =
[NSArray arrayWithObject: [NSNumber numberWithInt:
kABPersonAddressProperty]];
personView.allowsEditing = TRUE;
[self.navigationController pushViewController: personView animated:
TRUE];
CFRelease(addressBook);
[personView release];
--Code Sample 2--
// self.address is an AddressInfo instance
ABAddressBookRef addressBook = ABAddressBookCreate();
ABPersonViewController *personView = [ABPersonViewController new];
personView.personViewDelegate = self;
personView.addressBook = addressBook;
personView.displayedPerson =
ABAddressBookGetPersonWithRecordID(addressBook,
self.address.contactRecordID);
personView.displayedProperties =
[NSArray arrayWithObject: [NSNumber numberWithInt:
kABPersonAddressProperty]];
personView.allowsEditing = TRUE;
[self.navigationController pushViewController: personView animated:
TRUE];
CFRelease(addressBook);
[personView release];
Thanks,
David F.
