title: iOS MapKit Walking directions to point
body: <p>I am adding a map component to my iOS app and I would like to be able to show the user their current location and a path to a destination location (both using GPS coordinates).  I have found a lot of sample apps online that do this but what I want to add is the direction they should be facing at the final point.</p>
  
  <p>I thought that I might do this by adding a third point and have line drawn from the destination to the third point show direction but I can't seem to find any examples of how to do this.</p>
  
  <p>Thanks for the help.</p>
