So can anyone let me know ..how to apply similar styles to our overlays (i mean to the lines in the overlay)..

Thanks in advance....

Solution

You have to subclass MKOverlayPathView and define your own drawing behaviour..

"If you subclass, you should override the createPath method and use that method to build the appropriate path for the overlay. You can invalidate this path as needed and force the path to be recreated using whatever new data your subclass has obtained."
