Question

I’m using Cocos2D, and I need to access a parent method in a UIView that is added to a UIViewController from another class. My hierarchy goes like this:

Branch 1: window > viewController.view > glView > joinedMapsScene > joinedMapsLayer

Branch 2: window > viewController.view > foregroundLabelView

When my label class used to be part of Cocos2D, accessing was easy by doing something like this:

JoinedMapsScene *joinedMapsScene = (JoinedMapsScene*)self.parent;
[joinedMapsScene.tetraCounter incTetras:-1];

But now I need to call the method in foregroundLabelView from joinedMapsLayer. It may not be so much of a cocos2D question, but I’m just really confused about this sort of stuff still.

Answer 1

If I had understood well you want to retrieve the foregroundLabelView instance from joinedMapsLayer. There is a way but I don’t know if it’s optimal.
You can in your AppDelegate.h instantiate a foregroundLabelView.

Then when you init your foregroundLabelView you assign it to the AppDelegate foregroundLabelView: in your foregroundLabelView.m (you have to import AppDelegate.h), at the end of the init method you can do

AppDelegate * delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
delegate.foregroundLabelView = self;

Then whenever you want you can retrieve it by doing:

ForegroundLabelView * tmp = ((AppDelegate *)[[UIApplication sharedApplication] delegate]).foregroundLabelView;

and then access the method:

[tmp method];

I think this should work.
