title: UITabBarItem not showing icon on first launch after installation
body: <p>I have a UITabViewController inside a UINavigationController. As you can see on the image bellow the tab icons are set to system default "favorite" and "download" icons and they show properly when where looking in the storyboard.</p>
  
  <p><img src="https://i.stack.imgur.com/eJryN.png" alt="Storyboard"></p>
  
  <p>One of the tabs has a collection view and the other has a web view with a status bar.</p>
  
  <p>The problem is that when I deploy the app (to the simulator or a real device), the first time it opens the tab bar icon from the tab which is unselected doesn't show.</p>
  
  <p><img src="https://i.stack.imgur.com/J1r4W.png" alt="Error image"></p>
  
  <p>After i close and reopen the app the icon shows fine. The same thing happens if I select the tab.</p>
  
  <p><img src="https://i.stack.imgur.com/7fSZi.png" alt="Error after reopen"></p>
  
  <p>How can I make the image appear correctly the first open after installation? What am I doing wrong?</p>
  
  <p>I'm using Xcode 6 with iOS 8.2</p>
  
  <p>Thank you</p>
