How to create "Custom Label" in AddressBook programmaticly?

Answer 1

I had this exact same question. I couldn't find an answer so I just tried the guess and check method. The following code seems to work:

CFErrorRef error = NULL; 
ABAddressBookRef iPhoneAddressBook = ABAddressBookCreate();
ABRecordRef newPerson = ABPersonCreate();
ABRecordSetValue(newPerson, kABPersonFirstNameProperty, @"Jane", &error);
ABRecordSetValue(newPerson, kABPersonLastNameProperty, @"Smith", &error);

const CFStringRef customLabel = CFSTR( "mylabel" );

//phone
ABMutableMultiValueRef multiPhone = ABMultiValueCreateMutable(kABMultiStringPropertyType);
ABMultiValueAddValueAndLabel(multiPhone, @"1-444-444-444", kABPersonPhoneMainLabel, NULL);
ABMultiValueAddValueAndLabel(multiPhone, @"1-333-333-333", kABPersonPhoneMobileLabel, NULL);            
ABMultiValueAddValueAndLabel(multiPhone, @"1-666-666-666", kABOtherLabel, NULL);        
ABMultiValueAddValueAndLabel(multiPhone, @"1-555-555-555", customLabel, NULL); 
ABRecordSetValue(newPerson, kABPersonPhoneProperty, multiPhone,nil);
CFRelease(multiPhone);

ABAddressBookAddRecord(iPhoneAddressBook, newPerson, &error);
ABAddressBookSave(iPhoneAddressBook, &error);

if (error != NULL)
{   
    NSLog(@"Error!");   
}

If you check the address book, you will see a phone number with a custom label: mylabel
