Accessing Var from main Nib/Class - [global variables]

Question

I'm sure this is a simple solution and the problem is I'm just not thinking right. I just started programming in Objective C but have come a long way in the past 2 weeks. Pretty extensive knowledge in C# and some java.
Anyways, I've been creating an app and have streams working, CFNetwork working, network services discovery working and a tab bar with a custom View controller linking to one of the tab-bar buttons.
So when you click on one of the tab bar items it opens a new nib file. That nib loads a table view. When nib loads it hits a method which starts looking for network services and updates the table when it finds some.
Now the idea is is to have a selector on the cell and when you choose the service it adds same variable info, ip and port, back to a global variable which can be used through the entire app and all extra loaded nib files.
Out of all this, I don't know how to access global variables....prob should be the simplest thing to do out of all I've done. I have ideas of how it should be done but don't know how to access it.
Idea would be:
MainWindowNib has NSString var that is public with a getter setter. But how can I access that MainWindowNib var from a SecondView.nib file/class. There a way to get the parent of the secondView.Nib? I have no clue.
Any help would be great!
Thanks!

Answer 1

I'm still a bit confused how you access that method.
Main.nib class : UIApplication
NSString *port
SetupView.nib : NSViewController
view
-TableView added to view
-Seperate NSObject for TableViewDelegates
-When item selcted, pass NSString to [main port]
How do I get a pointer to port. I don't really understand how to do this with objective C.
In C# I would be something like: [Not exact syntax but u get the idea]
public Main : Form
public string port{get;set;}
Main()
sView SeconddForm = new SecondForm(this);
public SecondForm : Form
SecondView(Main main)
main.Port = "8080";
