如何创建segue执行和解开Segue的动画？

Question

我正在开发一个应用程序，我正在尝试用动画调用控制器，第二个视图控制器用动画，比如当我用segue调用第二个控制器时，第二个控制器从右边和第一个控制器开始向左移动，就像android推送弹出动画

我写了一些代码

class SegueFromRight: UIStoryboardSegue {
override func perform() {
    let src = self.source
    let dst = self.destination

    src.view.superview?.insertSubview(dst.view, aboveSubview: src.view)
    dst.view.transform = CGAffineTransform(translationX: src.view.frame.size.width*2, y: 0)
    //Double the X-Axis
    UIView.animate(withDuration: 0.25, delay: 0.0, options: UIView.AnimationOptions.curveEaseInOut, animations: {
        dst.view.transform = CGAffineTransform(translationX: 0, y: 0)
    }) { (finished) in
        src.present(dst, animated: false, completion: nil)
    }



}

}

但从这段代码新的控制器来自右侧，我需要移动当前控制器向左移动，如果有人可以帮助的话

尝试以下代码：

class CustomSegue: UIStoryboardSegue {
    override func perform() {
        let firstVCView: UIView = self.source.view
        let secondVCView: UIView = self.destination.view
        self.destination.modalPresentationStyle = .fullScreen

        let screenWidth = UIScreen.main.bounds.size.width
        let screenHeight = UIScreen.main.bounds.size.height

        secondVCView.frame = CGRect(x: screenWidth, y: 0, width: screenWidth, height: screenHeight)

        let window = UIApplication.shared.keyWindow
        window?.insertSubview(secondVCView, aboveSubview: firstVCView)

        UIView.animate(withDuration: 0.4, animations: { () -> Void in
            firstVCView.frame = firstVCView.frame.offsetBy(dx: -screenWidth, dy: 0.0)
            secondVCView.frame = secondVCView.frame.offsetBy(dx: -screenWidth, dy: 0.0)
               }) { (Finished) -> Void in
                self.source.present(self.destination as UIViewController,
                       animated: false,
                       completion: nil)
           }
    }
}


class CustomSegueUnwind: UIStoryboardSegue {
    override func perform() {
        let secondVCView: UIView = self.source.view
        let firstVCView: UIView = self.destination.view
        self.destination.modalPresentationStyle = .fullScreen

        let screenWidth = UIScreen.main.bounds.size.width

        let window = UIApplication.shared.keyWindow
        window?.insertSubview(firstVCView, aboveSubview: secondVCView)

        UIView.animate(withDuration: 0.4, animations: { () -> Void in
            firstVCView.frame = firstVCView.frame.offsetBy(dx: screenWidth, dy: 0.0)
            secondVCView.frame = secondVCView.frame.offsetBy(dx: screenWidth, dy: 0.0)
               }) { (Finished) -> Void in
                self.source.dismiss(animated: false, completion: nil)
           }
    }
}
