This isn't actually a CoreAnimation feature, but it is provided by Quartz. When switching to fullscreen mode, you can use the CGDisplayFade() function to get the system to do a smooth fade over some number of seconds. The Apple docs provide sample code on exactly how to do this:

If you invoke the fade synchronously, you can then start scheduling your CoreAnimation right after the fade has completed.
