title: setting tabbar translucent not working
body: <p>I want to make my tabbar half transparent by setting the translucent value to true. However it is not doing the trick. I have a TabBarVC assigned to the tab bar with the following code. The tab bar remains solid</p>
  
  <pre><code>class TabBarVC: UITabBarController {
  
  override func viewDidLoad() {
      super.viewDidLoad()
  
      // color of background -&gt; This works
      self.tabBar.barTintColor = UIColor.purpleColor()
  
      // color when selected -&gt; This works
      self.tabBar.tintColor = UIColor.redColor()
  
      // This does not work
      self.tabBar.translucent = true
  }
  </code></pre>
  
  <p>I also tried to do something like </p>
  
  <p>UIColor(red: 246.0/255, green: 246.0/255, blue: 246.0/255, alpha: 0.5)</p>
  
  <p>But it does not seem to work. I did a bit of search on Google but everyones issue seems to differ from mine. Could anyone help me out here?</p>
  
  <p>Thanks, </p>
