Swift 3:通过覆盖SKView在SpriteKit中制作暂停菜单？

import SpriteKit

class PauseMenuView: SKView {
    // 菜单视图
    let menuView = UIView(frame: CGRect(x: 0, y: 0, width: 200, height: 200))
    
    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        guard let touch = touches.first else { return }
        let location = touch.location(in: self)
        
        if menuView.frame.contains(location) {
            // 执行暂停操作
            // ...
        }
    }
}

// 在游戏场景中使用PauseMenuView
class GameScene: SKScene {
    override func didMove(to view: SKView) {
        let pauseMenuView = PauseMenuView(frame: view.frame)
        view.addSubview(pauseMenuView.menuView)
    }
}
