    CFIndex numberOfPeople = ABAddressBookGetPersonCount(addressBook);

    

    for(int i = 0; i < numberOfPeople; i++) {

        

        ABRecordRef person = CFArrayGetValueAtIndex( allPeople, i );

        

        NSString *firstName = (__bridge NSString *)(ABRecordCopyValue(person, kABPersonFirstNameProperty));

        NSString *lastName = (__bridge NSString *)(ABRecordCopyValue(person, kABPersonLastNameProperty));

        NSLog(@”Name:%@ %@”, firstName, lastName);

        

        ABMultiValueRef phoneNumbers = ABRecordCopyValue(person, kABPersonPhoneProperty);

        

        for (CFIndex i = 0; i < ABMultiValueGetCount(phoneNumbers); i++) {

            NSString *phoneNumber = (__bridge_transfer NSString *) ABMultiValueCopyValueAtIndex(phoneNumbers, i);
