tab.shown and tab.hidden have been killed. Although tab.shown is still working in some code bases and tab.hidden works one time only in some code bases.
Hi,
Refer to codepen ‘Ionic Sign-in, then Tabs’ example http://codepen.io/ionic/pen/kcjLb ,
the tab.hidden event is not fired if I add the following code in HomeTabCtrl.
.controller(‘HomeTabCtrl’, function($scope) {
console.log(‘HomeTabCtrl’);
$scope.$on(‘tab.shown’, function() {
// Maybe load some content here
console.log(‘Home tab.shown’);
});
$scope.$on(‘tab.hidden’, function() {
// Perhaps cycle out some data in memory here
console.log(‘Home tab.hidden’);
});
});

`tab.hidden` only fires once. `tab.shown` fires every time.

Instead, use `on-select` and `on-deselect` attribute callbacks.
Alternatively, … listen for $scope.$on('$destroy') in a controller inside
your tab.
