title: Accessing parentViewController's variables
body: <p>I want to allow a pushed to set parentViewController's instance variables. For instance, VC1 (the parent) has a bunch of textfields and what not which are filled from VC2 (the child). VC2 is pushed onto the stack by VC1. I've tried doing like <code>parentViewController.myString = "foo";</code> however since parentViewController is a UIViewController, I can't edit the myString field.</p>
  
  <p>Basically, my question is "How can I access the parent's instance variables?"</p>
  
  <p>Edit: I tried the solution here: <a href="https://stackoverflow.com/questions/1368757/setting-property-value-of-parent-viewcontroller-class-from-child-viewcontroller">Setting property value of parent viewcontroller class from child viewcontroller?</a> but it is chocked full of syntax errors.</p>
