Use AddressBook to add a contact

 

To add a contact, follow these steps:
1	Create ABAddressBookRef to reference the address book.
2	Call the ABPersonCreate () function to create an empty ABRecordRef and obtain an empty contact record.
3	Set the attribute value for ABRecordRef as needed. You can directly call the ABRecordSetValue () function to set the attribute value for the specified attribute of ABRecordRef. Set the properties of the label that can be specified by phone number or email. You must first create an ABMutableMultiValueRef, Then, call the ABMultiValueAddValueAndLabel () function to add multiple values to ABMutableMultiValueRef before calling the ABRecordSetValue () function to set the attribute value for the specified attribute of ABRecordRef.
4	Call the ABAddressBookAddRecord () function to add the specified ABRecordRef record to the address book.
5	Call the ABAddressBookSave () function to save the delete operation to the underlying address book.
