title: iPhone: What gets called after viewDidLoad before viewWillAppear?
body: <p>Really strange behaviour here.
  I've got a view with a scroll view inside, which contains my interface.</p>
  
  <p>In my <code>viewDidLoad</code>, I set the frame of my scrollView to have an origin of 0,0.</p>
  
  <p>I log the origin at the end of my <code>viewDidLoad</code>, and it's 0.
  However, at the start of my <code>viewWillAppear</code>, the origin is -20.
  Does anyone know what kind of method could get called that would do this?</p>
  
  <p>Thanks in advance</p>
