如何在添加到UIWindow后销毁VC？

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    // 执行销毁操作
    self.removeFromParentViewController()
}

// 在合适的地方创建并添加视图控制器到UIWindow
let viewController = YourViewController()
window.addSubview(viewController.view)
window.rootViewController = viewController

// 在需要销毁时，将弱引用置为nil
viewController = nil

class YourViewController: UIViewController {
    var dismissCallback: (() -> Void)?
    
    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        // 在视图消失时执行闭包回调
        dismissCallback?()
    }
}

// 在合适的地方创建并添加视图控制器到UIWindow
let viewController = YourViewController()
viewController.dismissCallback = {
    viewController = nil
}
window.addSubview(viewController.view)
window.rootViewController = viewController
