title: Help with stock ticker style scrolling using Core Animation
body: <p>I'm looking for some guidance on the best way to implement stock ticker style right-to-left scrolling of CALayers in Core Animation on OSX. I'm pretty new to Cocoa and don't know the best way to implement this. </p>
  
  <p>I have a continuous stream of news items and stock details that I turn into CALayers (made up of 1 image and a CATextLayer) and I want to animate the CALayers from right to left of my custom view.</p>
  
  <p>The news and stock information is constantly updating so I would like to add 1 item at a time to the view, scroll it right to left until the right-most point of the CALayer is showing, then add another CALayer to the view and start scrolling that as well. I would like to do this dynamic updating instead of taking a big snapshot of all my data, turning it into a big horizontal CALayer and scrolling that.</p>
  
  <p>I'm looking for guidance on how to achieve this sort of effect - </p>
  
  <p>do I manually animate each new CALayer along a path in the view? Or should I be using CAScrollLayer to achieve this effect?</p>
  
  <p>Many thanks
  Glen.</p>
