      context.nextFocusedView?.layer.shadowOffset = CGSizeZero
      context.nextFocusedView?.layer.shadowOpacity = 0.9;
      context.nextFocusedView?.layer.shadowRadius = 0;
      context.nextFocusedView?.layer.shadowColor= UIColor.orangeColor().CGColor
      context.previouslyFocusedView?.layer.shadowOpacity = 0;
