There’s lots of sites that talk about getting the AddressBook and such, but I wanted a good example and had a hard time finding code just to get the address book names.
Address Book Programming Guide for iPhone OS: Interacting Directly with the Address Book Database
Here's one way...
ABAddressBookRef addressBook = ABAddressBookCreate();
NSArray *people = (NSArray*) ABAddressBookCopyArrayOfAllPeople(addressBook);
NSInteger addressesCount = [people count];
NSMutableArray *allResults = [[[NSMutableArray alloc] init] autorelease];
for (CFIndex i = 0; i < addressesCount; i++) {
ABRecordRef record = [[people objectAtIndex:i] retain];
NSString *firstName = (NSString *)ABRecordCopyValue(record, kABPersonFirstNameProperty);
NSString *lastName = (NSString *)ABRecordCopyValue(record, kABPersonLastNameProperty);
NSString *fullName = nil;
if (ABPersonGetCompositeNameFormat() == kABPersonCompositeNameFormatFirstNameFirst)
fullName = [NSString stringWithFormat:@"%@ %@", firstName, lastName];
else
fullName = [NSString stringWithFormat:@"%@, %@", lastName, firstName];
if (![allResults containsObject:fullName])
[allResults addObject:fullName];
CFRelease(record);
[firstName release];
[lastName release];
}
CFRelease(addressBook);
[people release];
