ios - 使用自定义动画的弹出 Controller 后屏幕变黑

Question

我正在尝试使用呈现 Controller 和弹出 Controller (如关闭)的动画来插入 Controller 。

我正在使用这段代码来推送 Controller

    let transition:CATransition = CATransition()
    transition.duration = 0.4
    transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.linear)
    transition.type = CATransitionType.moveIn
    transition.subtype = CATransitionSubtype.fromTop
    AppDelegate.shared.window?.rootViewController!.view.layer.add(transition, forKey: kCATransition)
    self.push(articleDetailScene, animated: false)

并使用此代码弹出。

    let transition:CATransition = CATransition()
    transition.duration = 0.0
    transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeOut)
    transition.type = CATransitionType.reveal
    transition.subtype = CATransitionSubtype.fromBottom
    self.navigationController?.view.layer.add(transition, forKey: kCATransition)
    self.pop(animated: false)

放置 Controller 后，屏幕底部出现黑屏。我用过这个answers但这会为那个空间创建一个白屏，而不是在那个空间显示我的单元格。 Black screen when I don't use window background color to white和 When I set window background color to white .

您可以试试这个示例代码。

我正在添加过渡到 self.view 的窗口而不是 AppDelegate 的窗口

我有基础 View Controller 并有以下方法

func addTransitionForPush () {
    let transition = CATransition()
    transition.duration = 0.55
    transition.type = CATransitionType.push
    transition.subtype = CATransitionSubtype.fromBottom
    transition.fillMode = CAMediaTimingFillMode.forwards
    view.window?.layer.add(transition, forKey: kCATransition)
}


func addTransitionForPop () {
    let transition = CATransition()
    transition.duration = 0.55
    transition.type = CATransitionType.push
    transition.subtype = CATransitionSubtype.fromTop
    transition.fillMode = CAMediaTimingFillMode.backwards
    view.window?.layer.add(transition, forKey: kCATransition)
}

我如何在我的 View Controller 中使用它

用于推送 VC

@objc private func btnFilterTapped() {
    self.addTransitionForPush()
    let vc = self.storyboard........
    self.navigationController?.pushViewController(vc, animated: false)
}

弹出

    self.addTransitionForPop()
    self.navigationController?.popViewController(animated: false) 

如果您仍然遇到黑屏问题，请告诉我。
