title: iPhone - UINavigationController question
body: <p>I want to display some data on table, let's call it "TabeView" app.</p>
  
  <p>So I created a "navigation-based" application on XCode and it gives me 4 files in the "classes folder".</p>
  
  <ul>
  <li>RootViewController.h</li>
  <li>RootViewController.m</li>
  <li>TableViewAppDelegate.h</li>
  <li>TableViewAppDelegate.m</li>
  </ul>
  
  <p>Now, I wanted to set up the data in TableViewAppDelegate using the "didFinishLaunchingWithOptions" method, which I did using an array.</p>
  
  <p>Then, I need to "send" this array to the RootViewController. I have an array variable in RootViewController so I assume that I need to "set" the array variable in RootViewController from the TableViewAppDelegate. How can I do this?</p>
  
  <p>The problem I am having is, that I don't know how to set the array variable in RootViewController from TableViewAppDelegate. I want to know if something like below is possible</p>
  
  <pre><code>....
  [RootViewController setMyArray:myArray];
  [window addSubview:navigationController.view];
  [window makeKeyAndVisible];
  ....
  </code></pre>
  
  <p>But I have no idea how to call "RootViewController".</p>
  
  <p>Hopefully I made some sense. Thank you.</p>
