Is it possible to check a contact whether it is exits in contact list of iPhone or not?

I am developing an app in which i have to save contact in address book, but if the the contact is already saved in contact then it should not save.

But i have no idea is it possible to check a contact whether it is exits in contact list of iPhone or not?

Any help would be appreciated.

Thanks in advance.

     -(void)CheckContactIsExits{
  ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);

NSArray *allContacts = (__bridge NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);

ABRecordRef pet = ABPersonCreate();
ABRecordSetValue(pet, kABPersonFirstNameProperty, (__bridge CFStringRef)@"VoxSci Activation", nil);

for (id record in allContacts){
    ABRecordRef thisContact = (__bridge ABRecordRef)record;
    if (CFStringCompare(ABRecordCopyCompositeName(thisContact),
                        ABRecordCopyCompositeName(pet), 0) == kCFCompareEqualTo){

        NSLog(@"The contact already exists");
        //The contact already exists!
        isContactExits=YES;
    }

}
