hiding back button in ionic, angularjs

Question

I need to show and hide back button in different pages/views. I took reference from Justin Noel:

Answer 1

You can change the cache settings so that when the page is reloaded the controller is called again: http://ionicframework.com/docs/api/directive/ionNavView/

Answer 2

The hide-back-button attribute on <ion-view> did the trick for me: <ion-view hide-back-button="true">

See the official documentation here.

Answer 3

$ionicHistory.nextViewOptions({
    disableBack: true
  });

  $state.go('app.home');
