title: iOS 7.1 UINavigationbar and UIToolbar
body: <p>After upgrading Xcode in iOS7.1 my navigation bar and <code>UIToolbar</code> buttons are not shown with correct colour.</p>
  
  <p>When a view first appears the <code>UIToolbar</code> buttons all have the correct default blue colour and when I go to next page/view and come back to the previous view the toolbar buttons are shown in a grey colour.</p>
  
  <p>I have tried to add the blue colour in <code>viewDidLoad</code> and <code>viewWillAppear</code> but no luck. Can someone please help me?</p>
  
  <p>Thanks.</p>
