CAShapeLayer is a special purpose CALayer subclass for drawing animatable shapes using cubic Bezier splines. It's a part of the framework and is available for both (since iOS 3.0) and (since OS X v10.6 "Snow Leopard").

The shapes is defined using the path property and can be both filled and stroked using the fillColor and strokeColor properties. Note that the backgroundColor property inherited from CALayer does not fill the shape. The path of the shape is animatable (but doesn't support implicit animations) but the appearance of the animation is undefined if the two paths have a different number of control points or segments.

There are several properties (animatable) to configure how the shape is stroked and filled. Using these properties the stroke can for example get a moving dashed patten (commonly called "marching ants").

The strokeStart and strokeEnd properties can also be used to only stroke part of the shape or to animate the shape being stroked. Both values go from 0.0 (beginning of path) to 1.0 (end of path) and values in between are interpolated along the path.

The page about Paths in the Quartz 2D Programming Guide is a great resource for learning more about creating paths, stroking, rounding and joining paths, filling paths and creating dash patterns.
