title: With MapKit should I use Directions or make my own Overlays of routes?
body: <p>I am an absolute beginner in any programming, but am trying to learn by making an iOS app that shows a (my!) route on a map, using MapKit. Along the route there are annotations with specific info.</p>
  
  <p>I have two questions.</p>
  
  <ol>
  <li><p>What is better / easier, to try to use the MapKit directions between the annotations so MapKit displays the route (I want) following the road (I have to get directions between each annotation otherwise the route will not always be the one I want to show!) or somehow make an overlay png image of my route and use this?</p></li>
  <li><p>If it turns out to be better to use an Overlay, how do I make one and make sure it sits in the right place and zooms in and out?</p></li>
  </ol>
  
  <p>I have found many tutorials on how to add an Overlay, but can't seem to find much about how to make one that can be used in an app.</p>
