How to draw a MKPolyline on a MapView?

Question

I have an array of points to be drawn on a map, its already decoded:

- (void) drawRoute:(NSArray *) path {
    NSInteger numberOfSteps = path.count;

Answer 1

Just create MKPolyline with coordinates & add that polyLine to map view.

MKPolyline *polyLine = [MKPolyline polylineWithCoordinates:coordinates count:numberOfSteps];
    [map addOverlay:polyLine];

You will find an tutorial here on how to draw polyline over some coordinates. Edit: The url does not seems valid anymore. You can find the archived version of this url here.
