I want to load a existing contact using the address book view controller using only the uniqueID of the contact. How can a "person" record be defined using only the uniqueID?
ABPersonViewController *view = [[ABPersonViewController alloc] init];
view.personViewDelegate = self;
view.displayedPerson = person;
[self.navigationController pushViewController:view animated:YES];
Not sure if this it what you are asking, but you create a person for ABPersonViewController like this.
CFErrorRef err;
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, &err);
ABRecordRef person = (ABRecordRef)ABAddressBookGetPersonWithRecordID(addressBook, [contact.recordId intValue]);
personVC.displayedPerson = person;
