You see, I have doing my first application in xcode for iphone and it has emerged the big question (and I can not find solution anywhere) how I can create variables, and where they can be used by all classes of the project to able to consult and / or modify them from any other class when needed. The idea is to centralize this first and then learn how to get json or some database on some server the value of these variables, but well, that later. 
Thanks in advance. A greeting!

There are two ways to do what you want: centralize members (what you call variables) in your derived class NSApplication or create a singleton object. 
Find examples in Google.
