ios - 是否可以禁用 CATransition 的背景淡入淡出？

Question

鉴于以下情况:

let transition = CATransition()
    transition.duration = 0.5
    transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionDefault)
    transition.type = kCATransitionMoveIn
    transition.subtype = kCATransitionFromTop
    navigationController.view.layer.add(transition, forKey: kCATransition)
    navigationController.pushViewController(viewController, animated: false)

viewController 从底部过渡到顶部，就像模式过渡/segue 一样。但是，随着 View Controller 向上移动，背景开始淡化为黑色(以覆盖旧 View )。有什么方法可以阻止这种淡入淡出的发生吗？
