Need help accessing public Ivar

Hi,

I'm a newbie when it comes to iOS Programming. But after weeks of digging through API's, docs and much trial and error I can now proudly say that the idea I had in mind is up and running in my first iOS App. There are some things i am struggling with though.

For the sake of neat code and OOP (Object Oriented Programming) I wanted to separate some of my code in some separate class files. In this way I can separate my game logic from other code, say Twitter connection. This shouldn't be much of a problem, but I have some problems transferring data from the one to the other file. I'll try to illustrate what I'm doing (shortened):


// ViewAController.h
#import ViewBController.h

// ViewAController.m
-(void)viewDidLoad {
[ViewBController getIntX];
}

// ViewBController.h
int X;
+(int) getIntX;

// ViewBController.m
-(void)viewDidLoad {
X = 20;
}
-(int) getIntX {
return &(X);
}


Of course this is not my complete code, but it should give you an idea of what happens with this variable. Any help on how to acces a simple int X (directly or through getIntX) in ViewBController from ViewAController? Thanks a lot in advance!
