title: Drawing Routes with iPhone
body: <p>I am trying to make an iPhone application which can draw a path between two points (similar to Google Maps) but instead of the map i want to use any other image as a background, this path between the two points might not be straight and there might be multiple paths to get from one point to another then I want to draw the shortest path between the two points.</p>
  
  <p>I tried using the CGContext &amp; CGPath but I got stacked.</p>
  
  <p>Can you help me plz.</p>
  
  <p>Thanx,</p>
