如何在用户点击按钮的几秒钟内改变图像，然后在swift中恢复到原始图像？

let imageView = UIImageView(image: UIImage(named: "originalImage"))

let button = UIButton(type: .system)
button.setTitle("Change Image", for: .normal)
button.addTarget(self, action: #selector(changeImage), for: .touchUpInside)

@objc func changeImage() {
    // 改变图像
    UIView.transition(with: imageView, duration: 0.5, options: .transitionCrossDissolve, animations: {
        self.imageView.image = UIImage(named: "changedImage")
    }, completion: { _ in
        // 恢复到原始图像
        UIView.transition(with: self.imageView, duration: 0.5, options: .transitionCrossDissolve, animations: {
            self.imageView.image = UIImage(named: "originalImage")
        }, completion: nil)
    })
}

// 添加到视图中
view.addSubview(imageView)
view.addSubview(button)

// 设置布局约束或位置
imageView.translatesAutoresizingMaskIntoConstraints = false
button.translatesAutoresizingMaskIntoConstraints = false

NSLayoutConstraint.activate([
    imageView.centerXAnchor.constraint(equalTo: view.centerXAnchor),
    imageView.centerYAnchor.constraint(equalTo: view.centerYAnchor),
    button.centerXAnchor.constraint(equalTo: view.centerXAnchor),
    button.topAnchor.constraint(equalTo: imageView.bottomAnchor, constant: 20)
])
