Adding a route to MKMapView
So, I plan to draw some routes in MKMapView. What is the easiest way to do this on iOS? I'm not sure if the iPhone can calculate the routes if I give them two points (latitude, longitude). But if the iPhone can calculate the route, then this route may not be the route I want to do in order to go from point A to B.
Do I need a few points along the route and draw it? Since it seems really complicated, as the number of points grows linearly with increasing distance. Any suggestions?
