Show spinner while view loads

This is works with $ionicLoading... thank you!

$scope.$on('$ionicView.beforeEnter', function(e) {
                $ionicLoading.show({
                    animation: 'fade-in', showBackdrop: true
                });
            });
            $scope.$on('$ionicView.afterEnter', function(e) {
                $ionicLoading.hide();
            });
