title: Presenting a view controller with transparency and animation
body: <p>I'm setting <code>self.window.rootViewController.modalPresentationStyle = UIModalPresentationCurrentContext;</code> in my Application Delegate so that I can present a view controller and have the view be transparent (see this SO <a href="https://stackoverflow.com/questions/587681/how-to-use-presentmodalviewcontroller-to-create-a-transparent-view">question</a>).</p>
  
  <p>This works great, only remark is that I'm not able to animate when the view controller is presented. Has anyone gotten this to work? If not, what other options do I have?</p>
  
  <p>The view controller I'm presenting is a "walkthrough" that consists of a <code>UIScrollView</code> and <code>UIPageControl</code> that is supposed to "hover" over the interface so you can see the background of it slightly at the edges.</p>
