CGAffineTransform.identity不会重置设备旋转后正确转换

Question

我做一个自定义的过渡，如果存在的话动画后，设备将被旋转，然后destinationVC将被解雇，originVC变换是不正确的（未履行屏幕）。如果没有设备旋转，一切工作完全正常。是否有任何人能帮助我吗？

这里是我的现在和解雇动画代码：

func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
        guard let originViewController = transitionContext.viewController(forKey: .from),
            let destinationViewController = transitionContext.viewController(forKey: .to) else { return }

        destinationViewController.view.transform = CGAffineTransform(translationX: 0, y: destinationViewController.view.frame.height)
        let duration = transitionDuration(using: transitionContext)

        UIView.animate(withDuration: duration, animations: {
            destinationViewController.view.transform = CGAffineTransform(translationX: 0, y: 0)
            originViewController.view.transform = originViewController.view.transform.scaledBy(x: 0.95, y: 0.95)
            originViewController.view.layer.cornerRadius = 8.0
        }, completion: { completed in            
            transitionContext.completeTransition(completed)
        })
    }

func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
        guard let originViewController = transitionContext.viewController(forKey: .from),
            let destinationViewController = transitionContext.viewController(forKey: .to) else { return }

        let duration = transitionDuration(using: transitionContext)

        UIView.animate(withDuration: duration, animations: {
            originViewController.view.transform = CGAffineTransform(translationX: 0, y: destinationViewController.view.frame.height)
            destinationViewController.view.transform = CGAffineTransform.identity
            destinationViewController.view.layer.cornerRadius = 0.0
        }, completion: { completed in
            transitionContext.completeTransition(!transitionContext.transitionWasCancelled)
        })
    }

屏幕：目前动漫目前动画设备旋转解雇动画后后后前

编辑：当我添加destinationViewController.view.frame = transitionContext.finalFrame(for: destinationViewController)解雇动画一切似乎都做工精细，但我不知道这是否是正确的方式

在ViewC1添加一个子视图与领先，顶部，底部，尾随限制。全职工作代码

class ViewC1: UIViewController {

    @IBAction func presentNow(_ sender: Any) {
        let viewc = storyboard!.instantiateViewController(withIdentifier: "ViewC2") as! ViewC2
        viewc.transitioningDelegate = viewc
        viewc.modalPresentationStyle = .overCurrentContext
        present(viewc, animated: true, completion: nil)
    }

}

class ViewC2: UIViewController {

    let pres = PresentAnimator()
    let diss = DismissAnimator()

    @IBAction func dissmisNow(_ sender: Any) {
        dismiss(animated: true, completion: nil)
    }
}

extension ViewC2: UIViewControllerTransitioningDelegate {
    func animationController(forPresented presented: UIViewController, presenting: UIViewController, source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
        return pres
    }

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

class PresentAnimator: NSObject, UIViewControllerAnimatedTransitioning {

    func transitionDuration(using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
        return 1.0
    }

    func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
        guard let originViewController = transitionContext.viewController(forKey: .from),
            let destinationViewController = transitionContext.viewController(forKey: .to) else { return }

        transitionContext.containerView.addSubview(destinationViewController.view)
        destinationViewController.view.frame = transitionContext.containerView.bounds

        let originView = originViewController.view.subviews.first

        destinationViewController.view.transform = CGAffineTransform(translationX: 0, y: destinationViewController.view.frame.height)
        let duration = transitionDuration(using: transitionContext)

        UIView.animate(withDuration: duration, animations: {
            destinationViewController.view.transform = CGAffineTransform(translationX: 0, y: 0)
            originView?.transform = CGAffineTransform(scaleX: 0.95, y: 0.95)
            originView?.layer.cornerRadius = 8.0
        }, completion: { completed in
            transitionContext.completeTransition(completed)
        })
    }
}

class DismissAnimator: NSObject, UIViewControllerAnimatedTransitioning {

    func transitionDuration(using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
        return 1.0
    }

    func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
        guard let originViewController = transitionContext.viewController(forKey: .from),
            let destinationViewController = transitionContext.viewController(forKey: .to) else { return }

        let originView = destinationViewController.view.subviews.first
        let duration = transitionDuration(using: transitionContext)

        UIView.animate(withDuration: duration, animations: {
            originViewController.view.transform = CGAffineTransform(translationX: 0, y: destinationViewController.view.frame.height)
            originView?.transform = CGAffineTransform.identity
            originView?.layer.cornerRadius = 0.0
        }, completion: { completed in
            transitionContext.completeTransition(!transitionContext.transitionWasCancelled)
        })
    }
}

更新：或者你可以覆盖将旋转和旋转，如果你不希望使用qazxsw POI

view.subviews.first
