title: positioning frame does not work after move to iOS 4.2
body: <p>I'm having some trouble with moving a view:</p>
  
  <pre><code>- (void)viewDidLoad {
  
      CGRect newFrame = self.popUp.view.frame;
      newFrame.origin.y = self.view.bounds.size.height;
      self.popUp.view.frame = newFrame;
  
      [[self view] addSubview:[self.popUp view]];
  
      [super viewDidLoad];
  }
  </code></pre>
  
  <p>This should put the subview <code>popUp</code> below the current screen but it does not seem to be moving it.  I'm almost positive this was working pre-4.2.  Any ideas as to what might be going on?  Sorry for the vagueness.  If you have any questions feel free to ask.</p>
