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

    CLL         


        

Answer 1

MKPolyline *polyline = [MKPolyline polylineWithCoordinates:coordinates count:self.allPins.count];
[self.mapView addOverlay:polyline];

Check this http://pinkstone.co.uk/how-to-draw-an-mkpolyline-on-a-map-view/ and for swift http://rshankar.com/how-to-add-mapview-annotation-and-draw-polyline-in-swift/

Answer 2

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.

Answer 3

Done.

Was a very stupid thing, i didn't set the delegate for the MapView. Simply adding [map setDelegate:self]; did the trick.

Thank you anyway!.
