Have already tried these two links but it did not help.

Looking for a detailed tutorial/material for fetching device token of IOS using ionic.
To work with Ionic push notification you must be having recent Ionic version released i.e. Ionic version 2, if you have older version (lower than Ionic version 1) it will not work.
The CordovaPush,CordovaPush v5 are already deprecated so don't use them.
For detailed understanding of push notification in Ionic 2 please refer this ionic 2 push
