title: How to change the highlight colour of tabbar icons? (iPhone/iPad)
body: <p>I have been looking around online for an answer to this question for several days now with no success. Essentially what I want to do is change the highlight colour of the icons in my <code>UITabBar</code>. By default they are highlighted in blue when selected, however I have seen several apps that have managed to change this (eg. McDonalds app, shown below).</p>

  <p>What I would like to be able to do is set the highlight colour to red, if this is even possible please can someone help me?</p>
  
  <p><strong>NOTE:</strong> If it makes things any easier I'm targeting this app at users of <code>iOS5</code>+.</p>
