title: Single-Stage vs Two-Stage Animation for iPhone Apps?
body: <p>What are single-state and two-stage animation for rotating an iPhone window?</p>
  
  <p>This is the "error" message I get in the Debugger Console (nothing crashes):</p>
  
  <pre><code>Using two-stage rotation animation. To use the smoother single-stage animation, this application must remove two-stage method implementations.
  </code></pre>
  
  <p>I was working through the book "Beginning iPhone Development: Exploring the iPhone SDK" by Apress (Dave Mark, Jeff LaMarche) on the Swap Project.</p>
