I don't know Actionscript but it looks like it has a global dictionary of
objects that you can reference by name. There is nothing like "_root" in
Objective-C.

I see, this is where I was wrong. Yes Actionscript has this global dictionary. If you know the name of an object and its place in the hierarchy you can access it.

In my game I think of having a sort of "controller object" that
controls the whole state of the game. So I'd like to access it from
almost every other object further down the hierarchy. How would you do
this?

Is there a way to create the controller object and store its reference
in a global variable? Or is there another common way to do this that
I'm not thinking of?
Sorry for asking such dumb questions but I'm still new to this.

Thanks again in advance!

(not a dumb question)

You want to use the singelton pattern, see:
