I have a balloonGameViewController.h
and another class I made called balloon.h
I want to access some variables I set in balloon.h
As others said, you'll have to #import baloon.h
. But you did not say if these variables are global variables or ivars of a class. If they are ivars, you'll first have to find the instance of the class (the object) of which they are ivars. If you have that, and they are public or properties, you can access them as members of that object.
IOW, it is hard to tell if you don't tell us what kind of variables in balloon.h you want to access. But, see above.
