The MKPolygon class (iOS Developer Library) represents a shape consisting of one or more points that define a closed polygon

The MKPolygon class represents a shape consisting of one or more points that define a closed polygon. The points are connected end-to-end in the order they are provided. The first and last points are connected to each other to create the closed shape.

When creating a polygon, you can mask out portions of the polygon by specifying one or more interior polygons. For the polygons you specify, this class uses the even-odd fill rule to determine the final occupied area. When applied to overlapping polygons, this rule can cause specific regions to be masked out (and thereby removed) from the total occupied area.
