Xcode - Invoque a method from another class, without reinitializing it
===

I've a ViewController where I call a method from another class (TCP class), where I make a TCP connection to a server, that gives me a response. And I want to, when that TCP class, get's the response from the server, call another method from the ViewController.

Problems:
1- I'm a noob.
2- I'm initializing and allocating that first Viewcontroller on the TCP, and all my vars are reseted (something that I don't want).

So... What can I do to make it right? I just want to call a method from a different class, that is already allocated in memory.

Tks!
