title: How do I use CALayer with the iPhone?
body: <p>Currently, I have a UIView subclass that "stamps" a single 2px by 2px CGLayerRef across the screen, up to 160 x 240 times.</p>
  
  <p>I currently animate this by moving the UIView "up" the screen 2 pixels (actually, a UIImageView) and then drawing the next "row".</p>
  
  <p>Would using multiple CALayer layers speed up performance of rendering this animation?</p>
  
  <p>Are there tutorials, sample applications or code snippets for use of CALayer with the iPhone SDK? </p>
  
  <p>The reason I ask is that most of the code snippets I find that demonstrate simple examples of CALayer employ method calls that do not work with the iPhone SDK. I appreciate any advice or pointers.</p>
