Iphone Add contact to existing group in address book - iphone

Question

I am working on an iPhone application which works with the address book contacts. I am trying to get make groups in the contacts but the problem is when I run the application again the group is created again and the new contact is saved to that new created group.
// create address book record
ABAddressBookRef addressBook = ABAddressBookCreate();
// create a person
ABRecordRef person = ABPersonCreate();
// name of the new person
ABRecordSetValue(person, kABPersonFirstNameProperty, [index objectAtIndex:3], nil);
ABRecordSetValue(person, kABPersonLastNameProperty, [index objectAtIndex:0], nil);
//add the new person to the record
ABAddressBookAddRecord(addressBook, person, nil);
ABAddressBookSave(addressBook, &error);
ABAddressBookAddRecord(addressBook, group, &error); // add the group
ABAddressBookSave(addressBook, &error);
ABRecordRef group = ABGroupCreate(); //create a group
ABGroupAddMember(group, person, &error); // add the person to the group
ABAddressBookSave(addressBook, &error);
//save the record
ABAddressBookSave(addressBook, nil);
// relase the ABRecordRef variable
CFRelease(person);
That's the code I have been working on.

Answer 1

ABRecordRef group = ABGroupCreate(); ,
It will create a new group... If you wan to add member in existing group then you should get group by its id.
Updated Code
ABRecordRef group = ABAddressBookGetGroupWithRecordID(addressBookInstance,putYourGroupIdHere);
Thanks,

Answer 2

ABAddressBookRef ab = ABAddressBookCreate();
CFErrorRef error;
MySource *source = [sourcesAndGroups objectAtIndex:0];
ABRecordRef group = [source.groups objectAtIndex:self.IndexValue]; //Get the Group Name
NSString *firstName = ABRecordCopyValue(person, kABPersonFirstNameProperty);
NSString *lastName = ABRecordCopyValue(person, kABPersonLastNameProperty);
ABRecordSetValue(group, kABGroupNameProperty,[self nameForGroup:group], &error);
ABAddressBookAddRecord(ab, group, &error);
ABAddressBookSave(ab, &error);
//Create new Person and save to this group
ABRecordRef record = ABPersonCreate();
BOOL isSuccess ;
isSuccess = ABRecordSetValue(record, kABPersonNicknameProperty,lastName, &error);
isSuccess = ABRecordSetValue(record, kABPersonMiddleNameProperty, firstName , &error);
ABMultiValueRef phoneNumbers = (ABMultiValueRef)ABRecordCopyValue(person, kABPersonPhoneProperty);
if(ABMultiValueGetCount(phoneNumbers) == 0)
{
UIAlertView *av = [[UIAlertView alloc] initWithTitle:#"Phone Number" message:#"Please enter Phone number" delegate:self cancelButtonTitle:#"OK" otherButtonTitles: nil];
[av show];
return;
}
CFRelease(phoneNumbers);
NSString* phoneNumber = (NSString*)ABMultiValueCopyValueAtIndex(phoneNumbers, 0);
ABMutableMultiValueRef multi = ABRecordCopyValue(record, kABPersonEmailProperty);
ABMutableMultiValueRef copyOfPhones = ABMultiValueCreateMutable(kABPersonPhoneProperty);
ABMultiValueAddValueAndLabel(copyOfPhones, phoneNumber,kABPersonPhoneMobileLabel,NULL);
isSuccess = ABRecordSetValue(record, kABPersonPhoneProperty, copyOfPhones, &error);
isSuccess = ABRecordSetValue(record, kABPersonEmailProperty, multi, &error);
isSuccess = ABAddressBookAddRecord(ab, record, &error);
isSuccess = ABAddressBookSave(ab, &error);
ABGroupAddMember(group, record, &error);
NSLog(#"is success %d", isSuccess);
ABAddressBookSave(ab, &error);
CFRelease(group);
