title: How to implement an accordion view for an iPhone SDK app?
body: <p>Has anyone seen an implementation of an "accordion" (maybe called "animated outline") view for the iPhone? I found an example project for Cocoa, but before trying a port, I was hoping that someone has invented the wheel already.</p>
  
  <p>To make it clear, in a UIView, consider a stack of sections, each containing a header, and then some contents. When the user touches the header (or through some message/event), if the section is already open => close it; if the section is closed => open it and close any other open section. An example in jQuery looks like:
  <a href="http://docs.jquery.com/UI/Accordion" rel="noreferrer">http://docs.jquery.com/UI/Accordion</a></p>
  
  <p>In my case, I'd want to be able to put any UIView contents in each section. </p>
  
  <p>I'd be interested in just seeing some real apps who have implemented this - just to know it's possible!</p>
