How to get all phone numbers with labels for all contacts in address book?

I want to get all the phone numbers with diff labels like "iPhone", "home phone", "mobile number", "other numbers" , etc. for a contact stored in iPhone address book.

How do I get it?

Please help.

Thanks in advance.

I am trying: which is crashing

ABAddressBookRef ab=ABAddressBookCreate();

    CFArrayRef people = ABAddressBookCopyArrayOfAllPeople(ab);
    NSMutableArray *allNumbers = [[NSMutableArray alloc] initWithCapacity:CFArrayGetCount(people)];

    for (CFIndex i = 0; i < CFArrayGetCount(people); i++) {
        ABRecordRef person = CFArrayGetValueAtIndex(people, i);
        ABMultiValueRef numbers = ABRecordCopyValue(person, kABPersonPhoneProperty);

        for (CFIndex j=0; j < ABMultiValueGetCount(numbers); j++) {


            CFStringRef locLabel = ABMultiValueCopyLabelAtIndex(numbers, i);
            NSString *phoneLabel =(NSString*) ABAddressBookCopyLocalizedLabel(locLabel);

            CFStringRef phoneNumberRef = ABMultiValueCopyValueAtIndex(numbers, j);
            CFStringRef locLabel1 = ABMultiValueCopyLabelAtIndex(numbers, j);
            NSString *phoneLabel1 =(NSString*) ABAddressBookCopyLocalizedLabel(locLabel);

             NSLog(@" ####### phone no -> %@ , phone label -> %@  #######)", locLabel1, phoneLabel1);
            //CFRelease(phones);
            NSString *phoneNumber = (NSString *)phoneNumberRef;
            CFRelease(phoneNumberRef);
            CFRelease(locLabel);
            NSLog(@"phone no -> %@ , phone label -> %@)", phoneNumber, phoneLabel);
            [phoneNumber release];
        }
        CFRelease(numbers);
    }

    CFRelease(people);

Solved it this way:

  ABAddressBookRef addressBook = ABAddressBookCreate();
CFArrayRef all = ABAddressBookCopyArrayOfAllPeople(addressBook);
CFIndex n = ABAddressBookGetPersonCount(addressBook);

for( int i = 0 ; i < n ; i++ )
{
    ABRecordRef ref = CFArrayGetValueAtIndex(all, i);
    NSString *firstName = (NSString *)ABRecordCopyValue(ref, kABPersonFirstNameProperty);
    NSLog(@"Name %@", firstName);

    ABMultiValueRef phones = ABRecordCopyValue(ref, kABPersonPhoneProperty);
    for(CFIndex j = 0; j < ABMultiValueGetCount(phones); j++)
    {

        CFStringRef locLabel1 = ABMultiValueCopyLabelAtIndex(phones, j);
        NSString *phoneLabel1 =(NSString*) ABAddressBookCopyLocalizedLabel(locLabel1);

          NSLog(@"  ### %@  --- %@ ### )", locLabel1, phoneLabel1);

    }
}
