Overview

The MKPolylineView class provides the visual representation for an MKPolyline annotation object. This view strokes the path represented by the annotation. (This class does not fill the area enclosed by the path.) You can change the color and other drawing attributes of the path by modifying the properties inherited from the MKOverlayPathView class. This class is typically used as is and not subclassed.
