Answer Source

In iOS it could be done using -

Register the external change call back notifier-

ABAddressBookRef ntificationaddressbook = ABAddressBookCreate();
    ABAddressBookRegisterExternalChangeCallback(ntificationaddressbook, MyAddressBookExternalChangeCallback, self);

Implement the call back -

void MyAddressBookExternalChangeCallback (ABAddressBookRef ntificationaddressbook,CFDictionaryRef info,void *context)
    // called when there is any change in AddressBook

For more details you can refer this link-
