Swift 从SKScene显示UIViewController时显示黑屏

这段代码旨在向用户展示

UIViewController

“菜单”，而是用一个黑屏向用户致意

let currentViewController:UIViewController=UIApplication.shared.keyWindow!.rootViewController!
let mymenu = menu()
currentViewController.present(mymenu, animated: true, completion: nil)

---

我正在从一个

SKScene

过渡到从另一个

SKScene

呈现一个

SKScene

，例如，您应该执行以下操作：

let nextScene = MainScene(size: self.scene!.size)
self.scene?.view?.presentScene(nextScene, transition: SKTransition.doorway(withDuration: 1))

您不需要检索

currentViewController

，因为您始终可以访问

场景的
视图


正如下面对注释所解释的，有多种方法可以调用实现到游戏viewController的函数，其中一种方法可以是创建代理/协议，如以下代码所示：

游戏场景示例：

import SpriteKit
protocol GameViewControllerDelegate: class {
    func callMethod(inputProperty:String)
}
class GameScene: SKScene {
    weak var gameViewControllerDelegate:GameViewControllerDelegate?
    override func didMove(to view: SKView) {
        gameViewControllerDelegate?.callMethod(inputProperty: "call game view controller method")
    }
}

class GameViewController: UIViewController, GameViewControllerDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()
        if let view = self.view as! SKView? {
            // Load the SKScene from 'GameScene.sks'
            if let scene = SKScene(fileNamed: "GameScene") {
                let gameScene = scene as! GameScene
                gameScene.gameViewControllerDelegate = self
                gameScene.scaleMode = .aspectFill
                view.presentScene(gameScene)
            }
            view.ignoresSiblingOrder = true
            view.showsFPS = true
            view.showsNodeCount = true
        }
    }
    func callMethod(inputProperty:String) {
        print("inputProperty is: ",inputProperty)
    }
}

游戏视图控制器示例：

import SpriteKit
protocol GameViewControllerDelegate: class {
    func callMethod(inputProperty:String)
}
class GameScene: SKScene {
    weak var gameViewControllerDelegate:GameViewControllerDelegate?
    override func didMove(to view: SKView) {
        gameViewControllerDelegate?.callMethod(inputProperty: "call game view controller method")
    }
}

class GameViewController: UIViewController, GameViewControllerDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()
        if let view = self.view as! SKView? {
            // Load the SKScene from 'GameScene.sks'
            if let scene = SKScene(fileNamed: "GameScene") {
                let gameScene = scene as! GameScene
                gameScene.gameViewControllerDelegate = self
                gameScene.scaleMode = .aspectFill
                view.presentScene(gameScene)
            }
            view.ignoresSiblingOrder = true
            view.showsFPS = true
            view.showsNodeCount = true
        }
    }
    func callMethod(inputProperty:String) {
        print("inputProperty is: ",inputProperty)
    }
}

输出：

import SpriteKit
protocol GameViewControllerDelegate: class {
    func callMethod(inputProperty:String)
}
class GameScene: SKScene {
    weak var gameViewControllerDelegate:GameViewControllerDelegate?
    override func didMove(to view: SKView) {
        gameViewControllerDelegate?.callMethod(inputProperty: "call game view controller method")
    }
}

class GameViewController: UIViewController, GameViewControllerDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()
        if let view = self.view as! SKView? {
            // Load the SKScene from 'GameScene.sks'
            if let scene = SKScene(fileNamed: "GameScene") {
                let gameScene = scene as! GameScene
                gameScene.gameViewControllerDelegate = self
                gameScene.scaleMode = .aspectFill
                view.presentScene(gameScene)
            }
            view.ignoresSiblingOrder = true
            view.showsFPS = true
            view.showsNodeCount = true
        }
    }
    func callMethod(inputProperty:String) {
        print("inputProperty is: ",inputProperty)
    }
}

但我正在转换为视图，而不是SKScene。您应该区分
UIKit
元素和
Sprite kit
元素，特别是在游戏中使用时。您也没有视图，但有一个包含
SKScene
的
SKView
，因此无法“转换”到视图对不起，我不明白。我想在我的SKScene中调用一个函数，它将为播放器提供uiviewcontroller。啊，对了，这是另一个故事：-），无论如何，你可以在你的场景中提供播放器视图或任何其他
UIKit
视图
self.scene？.view？.addSubview（）
好的，抱歉，谢谢，但是我如何为播放器提供uiviewcontroller？
