Answer 1

From this.

ABRecordRef aRecord = ABPersonCreate(); 
    CFErrorRef  anError = NULL; 
    ABRecordSetValue(aRecord, kABPersonFirstNameProperty, 
                     CFSTR("Jijo"), &anError); 
    ABRecordSetValue(aRecord, kABPersonLastNameProperty, 
                     CFSTR("Pulikkottil"), &anError); 
    if (anError != NULL) { 

        NSLog(@"error while creating..");
    } 
    CFStringRef firstName, lastName; 
    firstName = ABRecordCopyValue(aRecord, kABPersonFirstNameProperty); 
    lastName  = ABRecordCopyValue(aRecord, kABPersonLastNameProperty); 




    ABAddressBookRef addressBook; 
    CFErrorRef error = NULL; 
    addressBook = ABAddressBookCreate(); 

    BOOL isAdded = ABAddressBookAddRecord (
                            addressBook,
                            aRecord,
                             &error
    );

    if(isAdded){

        NSLog(@"added..");
    }
    if (error != NULL) {
        NSLog(@"ABAddressBookAddRecord %@", error);
    } 
    error = NULL;

    BOOL isSaved = ABAddressBookSave (
                       addressBook,
                       &error
    );

    if(isSaved){

        NSLog(@"saved..");
    }

    if (error != NULL) {
        NSLog(@"ABAddressBookSave %@", error);
    } 

    CFRelease(aRecord); 
    CFRelease(firstName); 
    CFRelease(lastName); 
    CFRelease(addressBook);

If you need to store data in there, I think your only option is kABPersonNoteProperty, but I'm no expert on this.

Edit: link.

Answer: nope!

Edit: you can also prompt the user to add an address book entry as done here.
