Read person record:

ABAddressBookRef addressBook = ABAddressBookCreate();

CFArrayRef people = ABAddressBookCopyArrayOfAllPeople(addressBook);

CFMutableArrayRef peopleMutable = CFArrayCreateMutableCopy(

kCFAllocatorDefault,

CFArrayGetCount(people),

people

);

[peopleMutable sortUsingFunction:ABPersonComparePeopleByName

context:(void*)sortOrdering];

/* the equivalent in Procedural C:

CFArraySortValues (

peopleMutable,

CFRangeMake(0, CFArrayGetCount(peopleMutable)),

(CFComparatorFunction)ABPersonComparePeopleByName,

(void*)ABPersonGetSortOrdering()

);

*/

CFRelease(addressBook);

CFRelease(people);

CFRelease(peopleMutable);
