Import contact groups in ios

Question

I want to be able to import contact group data when I import contacts in my application. Is there a method for me to get this data from iOS or am I just limited to get contact details?

Answer 1

- (void)fetchMobileContacts
{

CFErrorRef *error = NULL;
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, error);

__block BOOL accessGranted = NO;
if (ABAddressBookRequestAccessWithCompletion != NULL) { // we're on iOS 6
    dispatch_semaphore_t sema = dispatch_semaphore_create(0);
    ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
        accessGranted = granted;
        dispatch_semaphore_signal(sema);
    });
    dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
}
else { // we're on iOS 5 or older
    accessGranted = YES;
}

if (accessGranted) {
    // Do whatever you want here.
    CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople( addressBook );
    CFIndex nPeople = ABAddressBookGetPersonCount( addressBook );
    NSMutableArray *validAddress = [NSMutableArray new];
    for ( int i = 0; i < nPeople; i++ )
    {
        ABRecordRef person = CFArrayGetValueAtIndex( allPeople, i );
        NSString *firstName = (__bridge NSString *)(ABRecordCopyValue(person, kABPersonFirstNameProperty));
        NSString *lastName = (__bridge NSString *)(ABRecordCopyValue(person, kABPersonLastNameProperty));
        NSString *fullName = [NSString stringWithFormat:@"%@ %@",firstName,lastName];

        ABMultiValueRef phoneNumberProperty = ABRecordCopyValue(person, kABPersonPhoneProperty);
        NSArray* phoneNumbers = (__bridge NSArray*)ABMultiValueCopyArrayOfAllValues(phoneNumberProperty);

        ABMultiValueRef emailProperty = ABRecordCopyValue(person, kABPersonEmailProperty);
        NSArray* emails = (__bridge NSArray*)ABMultiValueCopyArrayOfAllValues(emailProperty);

        NSString *email = @"";
        NSString *phone = @"";

        if(phoneNumbers.count) phone = [phoneNumbers objectAtIndex:0];
        if(emails.count) email = [phoneNumbers objectAtIndex:0];
        if(email.length || phone.length){
            NSDictionary *contactInfo = @{kContactName: fullName, kContactPhone: phone, kContactEmail: fullName};
            [validAddress addObject:contactInfo];
        }
    }
    MobileContactsViewController *contactsVC = [[MobileContactsViewController alloc] initWithContacts:validAddress];
    contactsVC.hidesBottomBarWhenPushed = YES;
    [self.navigationController pushViewController:contactsVC animated:YES];
}
}

Answer 2

This is how I import contact information into my app. I store the info in an NSDictionary so I can read it back later easily. It's in no way pretty, but works very well.
