Hidden nav-bar using $state.go() with disabled caching (Beta 14)

You could also show the nav-bar after entering the view by using the following piece of code in your controller.

$scope.$on('$ionicView.enter', function(e) {
    $ionicNavBarDelegate.showBar(true);
});

dont forget to inject $ionicNavBarDelegate

Also it's probably going to be fixed in Ionic 1.3 https://github.com/driftyco/ionic/issues/3852
