从容器到表格的模态的自定义过渡

Question

我有一个视图控制器，其中一些容器中包含导航控制器，表格视图，其他标准控制器等...

我想从其中一个容器中选择一个模态表单，该容器将进行动画处理，扩展，移动（原始内容仍显示在下面，或者我不在乎），以进行扩展。在模态表单视图中使用“相同”控制器完成过渡

我在实施它时花费了很多时间，框架的动画存在很多错误，有人可以帮助我，还是将我重定向到一个合适的文档？

这是我要执行的操作的示例，但是此代码不起作用，并且我尝试了几种动画技术（仅在动画中使用layoutIfNeed，使用CGTransformation在此处更改帧的值等...）

extension PlayersListTableViewController: UIViewControllerTransitioningDelegate {
    func animationController(forPresented presented: UIViewController, presenting: UIViewController, source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
        guard let superview = self.navigationController?.view else { return nil }
        guard let globalFrame = superview.superview?.convert(superview.frame, to: nil) else { return nil }
        transition.originFrame = globalFrame
        transition.presenting = true

        return transition
    }

    func animationController(forDismissed dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
        return nil
    }
}

class FormAnimator: NSObject, UIViewControllerAnimatedTransitioning {
    let duration = 5.0
    var presenting = true
    var originFrame = CGRect.zero

    func transitionDuration(using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
        return duration
    }

    func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
        let containerView = transitionContext.containerView

        let toView = transitionContext.view(forKey: .to)!
        let finalView = toView



        let initialFrame = originFrame
        let finalFrame = finalView.frame

        finalView.frame.origin = initialFrame.origin
        finalView.frame.size = initialFrame.size
        finalView.clipsToBounds = true

        containerView.addSubview(finalView)
        containerView.bringSubviewToFront(finalView)

        finalView.frame = finalFrame

        UIView.animate(withDuration: duration, delay:0.0,
                       animations: {
                        finalView.layoutIfNeeded()
        },
                       completion: { _ in
                        print(finalView.frame)
                        transitionContext.completeTransition(true)
        }
        )

    }
