title: Changing button titles from different .m files
body: <p>I am writing some code that works in several languages. When the user changes the language I need to change all the screen prompts and button text. When I am in the .m for that screen I simply type:</p>
  
  <pre><code>    [[self.tabBarController.viewControllers objectAtIndex:1] setTitle:@"Setup"];
  </code></pre>
  
  <p>But how to I change the prompts in the other screens without having to go to each .m and make the changes. I am assuming that "self" can be replaced to allow me to do this.</p>
