Instance Method

getCoordinates:range:

Retrieves one or more points associated with the shape and converts them to coordinate values.

Declaration

- (void)getCoordinates:(CLLocationCoordinate2D *)coords range:(NSRange)range;

Parameters

coords

On input, you must provide a C array of structures large enough to hold the desired number of coordinates. On output, this structure contains the requested coordinate data.

range

The range of points you want. The location field indicates the first point you are requesting, with 0 being the first point, 1 being the second point, and so on. The length field indicates the number of points you want. The array in coords must be large enough to accommodate the number of requested coordinates.

Discussion

This method converts the map points into coordinates before returning them to you. If you want the value of each point specified as a map point, you can access the values directly using the points method.
