title: Different colors for TabBar items in Tab Bar Controller
body: <p>I have Tab Bar Controller with few tabs.</p>
  
  <ul>
  <li><p>All tab items should have same non-selected color for image and text.</p></li>
  <li><p>All tab items should have different selected color for image and
  text.</p></li>
  </ul>
  
  <p>I am ready to create images with colors needed for selected and non-selected items. And I know how to change this colors for all tabs from AppDelegate </p>
  
  <pre><code>    UITabBar.appearance().tintColor = UIColorFromRGB(rgbValue: MY_COLOR, aplhaValue: 1.0)
      UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColorFromRGB(rgbValue: MY_COLOR, aplhaValue: 1.0)], for: UIControlState.selected)
      UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.white], for: UIControlState.normal)
  </code></pre>
  
  <p>But I want to make different colors for different items.</p>
