iPhone dev mail, contacts, calendar settings

I need to access a "Sort Order" and开发者_开发知识库 "Display Order" preferences under Settings -> Mail, Contacts, Calendar.

Is there any example how to do that?

Thank you /Alex

From the ABPerson reference, see ABPersonGetSortOrdering() and ABPersonGetCompositeNameFormat(). You'll have to #include <AddressBook/AddressBook.h> and link against AddressBook.framework.

There is no public API to change this setting.
