title: heat map on map view in iphone....?
body: <p>My client wants to show a heat map of all the countries from where ever he recieves updates. Like if one of his shop closed in America he wants me to show entire country in red color and if a new one opened in Brazil then it should show brazil in green color. And when I tap on brazil it zooms in and shows pin annotations for where ever the shops are opened and closed.</p>
  
  <p>So my question is can someone guide me how to show a particular country on map view in a particular color..</p>
  
  <p>Thanks in advance.</p>
