Black Color Behind UIView while UIView Transition Animation

Question

I am doing transition animation using the following block. But I observed that during flip animation a black color layer appears beneath the UIView. Is there any way to set custom color to that layer.

UIView.transitionWithView(ibContainerView, duration: 0.2, options: [.CurveEaseOut,.TransitionFlipFromLeft], animations: {
                self.ibContainerView.addSubview(self.ibInstagramView)

                }, completion:nil)

        }

Answer 1

try changing border width and color

self.yourView.layer.borderWidth = 0
self.yourView.layer.borderColor = UIColor.clearColor().CGColor

Answer 2

You need to change the background color of the actual ViewController, which holds all these views.
