想翻转两个视图，使一个视图隐藏另一个显示swift

Question

我想从顶部或左侧翻转两个视图，方向不是什么大问题基本上我想翻转一个视图，以便在动画中隐藏一个视图或和其他显示如卡片翻转我想要这个但是有两个视图 https://www.youtube.com/watch?v=4kSLbuB-MlU

我在 objective C 中找到了它（也许） link附上 how to flip two views at once? 图片也已附上

我尝试了下面的方法，但找不到合适的解决方案

UIView.transition(from: vu1, to: vu2, duration: 1, options: .transitionFlipFromBottom, completion: { _ in
        })

也试过这个但没有帮助

   func flipTransition (with view1: UIView, view2: UIView, isReverse: Bool = true) {
        var transitionOptions = UIView.AnimationOptions()
        transitionOptions = isReverse ? [.transitionFlipFromLeft] : [.transitionFlipFromRight]

        UIView.transition(with: view1, duration: 1.5, options: transitionOptions, animations: {
            view1.isHidden = true
        })

        UIView.transition(with: view2, duration: 1.5, options: transitionOptions, animations: {
            view2.isHidden = false
        })
    }

UIView.transition(with 适用于容器视图，因此您可以尝试将子视图放入容器视图并在容器视图上应用 UIView.transition。因为你没有添加任何代码，所以我假设这里没有什么可以回答的

class ViewController: UIViewController {
    @IBOutlet weak var button: UIButton!
    let view1 = UIView()
    let view2 = UIView()
    let containerView = UIView()

    override func viewDidLoad() {
        super.viewDidLoad()

        view1.backgroundColor = UIColor.red
        view2.backgroundColor = UIColor.green

        view.addSubview(containerView)
        containerView.addSubview(view1)
        containerView.addSubview(view2)

        containerView.translatesAutoresizingMaskIntoConstraints = false
        view1.translatesAutoresizingMaskIntoConstraints = false
        view2.translatesAutoresizingMaskIntoConstraints = false

        NSLayoutConstraint.activate([
            containerView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
            containerView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
            containerView.bottomAnchor.constraint(equalTo: view.bottomAnchor),
            containerView.topAnchor.constraint(equalTo: view.topAnchor, constant: 100),

            view1.leadingAnchor.constraint(equalTo: containerView.leadingAnchor),
            view1.trailingAnchor.constraint(equalTo: containerView.trailingAnchor),
            view1.bottomAnchor.constraint(equalTo: containerView.bottomAnchor),
            view1.topAnchor.constraint(equalTo: containerView.topAnchor, constant: 100),

            view2.leadingAnchor.constraint(equalTo: containerView.leadingAnchor),
            view2.trailingAnchor.constraint(equalTo: containerView.trailingAnchor),
            view2.bottomAnchor.constraint(equalTo: containerView.bottomAnchor),
            view2.topAnchor.constraint(equalTo: containerView.topAnchor, constant: 100)
        ])

        view1.isHidden = false
        view2.isHidden = true
    }

    @IBAction func changeTapped() {
        UIView.transition(with: containerView,
                          duration: 1.0,
                          options: .transitionFlipFromBottom, animations: {[weak self] in
            guard let self = self else { return }
            self.view1.isHidden = !self.view1.isHidden
            self.view2.isHidden = !self.view2.isHidden
        })
    }
