title: iOS 7 change tabBar selected icon
body: <p>I've created a tabBar in storyboard and set a custom image. I want to use a different image for the "selected" state, I know I can't set that image using storyboard but how do I do it programmatically?</p>
  
  <p>I also want to change the icon tint colour in code but can't make that happen either.</p>
  
  <p>I would significantly appreciate any help please.</p>
