The CNSaveRequest class defines a save request operation for contacts.

The CNSaveRequest class creates a new save request for each save operation on the contact store. You can batch multiple changes into one save request (note that these changes only apply to objects). In the case of overlapping changes in multiple or concurrent save requests, the last change wins. If you try to add an object (that is, a contact, or a group,) that already exists in the contact store, the CNErrorCodeInsertedRecordAlreadyExists error occurs and the CNErrorUserInfoAffectedRecordsKey array is updated to contain the object you tried to add. If you try to update or delete an object that is not present in the contact store, the save request does not perform the update or deletion, the CNErrorCodeRecordDoesNotExist error occurs, and the CNErrorUserInfoAffectedRecordsKey array is updated to contain the object you tried to update or delete. Do not access objects in the save request while a save request is executing.
