The question: The Ionic supports apply different animation in closing a modal? The action of closing, by default, apparently has a similar animation with slide-out down '.
This is an example from how I made a custom animation, and I think it came from the forum from a while back. It utilizes ngAnimate to add the appropriate css classes that do the actual animation. So create your modal:
$ionicModal.fromTemplateUrl('template-file.html', {
id: 'modal-id',
scope: $scope,
animation: 'zoom-from-center' //css class to apply animation
}).then(function (modal) {
$scope.myModal = modal; //this applies the modal reference to the $scope
});
