Parse Cloud Code Push Notifications - ios

Question

I have a Class "Storybaord" and there are two instances of when to send a Push Notification.
A user likes a post - [postObject addUniqueObject: [PFUser currentUser] forKey:#"likes"];
A user comments on a post - [postObject addUniqueObject: self.comment forKey:#"comments"];
In my cloud code I use Parse.Cloud.afterSave but I am unsure of how to distinguish between the two, and also determine if they even happen, because there are other occasions of saving the postObject without needing to send a push.
Cloud Code:
Parse.Cloud.afterSave("Storyboard", function(request){
var user = Parse.User.current();
var postUser = request.object.get('userId');
var pushQuery = new Parse.Query(Parse.Installation);
pushQuery.equalTo ('userId', postUser);
Parse.Push.send({
where: pushQuery,
data: {
alert: "Liked Your Post"
}
}, {
success: function(){
},
error: function(){
}
});
});

If your insistent on sending the push via cloud code, all you have to do is set a conditional statement client-side and act accordingly, that way you can opt to send or not according to your needs, since you mentioned something about selectively sending pushing:
if (self.likeButton.isSelected) {
[PFCloud callFunctionInBackground:#"alertAuthor" withParameters:#{#"message", [NSString stringWithFormat:#"%# liked your post!", [PFUser currentUser].username]}
}
if (self.commentEntered) {
[PFCloud callFunctionInBackground:#"alertAuthor" withParameters:#{#"message", [NSString stringWithFormat:#"%# commented on your post!", [PFUser currentUser].username]}
}
And simply send a push using the parameters via cloud code:
Parse.Cloud.define("alertAuthor", function(request,response){
var query = new Parse.Query(Parse.User);
var message = request.params.message;
query.equalTo('username', 'postUser');
Parse.Push.send({
where: query,
data : {
alert: message,
badge: "Increment",
sound: "",
}
}, {
success: function() {
//Success
},
error: function(error) {
//Oops
}
});
});
