如何:授予SKScene对dismiss() UIKit方法的访问权限

import UIKit

class CustomScene: SKScene, UIViewControllerDelegate {
    // ...
}

class CustomScene: SKScene, UIViewControllerDelegate {
    weak var viewController: UIViewController?
    
    // 在需要的地方设置viewController属性，例如在didMove(to view: SKView)方法中：
    override func didMove(to view: SKView) {
        super.didMove(to: view)
        
        // 获取当前的视图控制器
        if let viewController = view.window?.rootViewController {
            self.viewController = viewController
            viewController.delegate = self
        }
    }
    
    // ...
}

class CustomScene: SKScene, UIViewControllerDelegate {
    // ...
    
    func closeCurrentViewController() {
        viewController?.dismiss(animated: true, completion: nil)
    }
    
    // ...
}
