After retrieving the reference to the address book database, you can call the ABGroupCreate function to create a new group entry. However, you must perform a few more operations before you can insert this group into the address book operation. The first thing you have to do is set the name of this group using the ABRecordSetValue function with the kABGroupNameProperty property, as shown in the example code.
