title: Paint Bucket in iOS
body: <p>I'm stuck on a problem and needed some help or guide for a possible solution.</p>
  
  <p>Basically in my application there will be a map with several zones. 
  The user can select any of these areas, at that time this area is filled with a color.</p>
  
  <p>Imagine a map like this one, so i need to be able to change the color of only one country.

  <p>Something like what happens in the books of paintings (<a href="https://itunes.apple.com/pt/app/colorfly-best-coloring-book/id1020187921?mt=8" rel="nofollow noreferrer">https://itunes.apple.com/pt/app/colorfly-best-coloring-book/id1020187921?mt=8</a>), or <strong>Paint Bucket</strong> command in the Photoshop .</p>
  
  <p>Any idea how to get something like this on iOS ?</p>
  
  <p>Thanks in advance</p>
