Question

所以我想自定义Viewcontroller Presentation，因为使用我的代码viewcontroller冻结了半秒钟，然后显示了其他viewcontroller。

extension UIViewController {

func presentDetail (_ viewControllerToPresent : UIViewController) {
    let transition = CATransition()
    transition.duration = 0.3
    transition.type = .push
    transition.subtype = .fromLeft
    self.view.window?.layer.add(transition, forKey: kCATransition)

    present(viewControllerToPresent, animated: false, completion: nil)
}
}

Answer 1

对于自定义演示，您需要在presentedView上提供transitionDelegate，然后提供所需的动画师对象。

可能的最小实现似乎是在func presentationController(forPresented presented: UIViewController, presenting: UIViewController?, source: UIViewController) -> UIPresentationController?中提供UIPresentationController

ViewController之间的滞后自定义过渡
