Where to Go From Here?

Congratulations! You’ve completed the great CALayer Tour. You have seen nine examples of how to use CALayer and its many subclasses. You can download the completed version of the project using the Download Materials button at the top or bottom of this tutorial.

But don’t stop here! Open a new project, or work with one of your existing ones, and see how you can use layers. You may be able to achieve better performance, or you might add some new animations to wow your users — and yourself! :]
