从 SKScene 呈现 UIViewController 显示黑屏

Question

此代码旨在向用户显示UIViewController“菜单”，而是以黑屏迎接他们。

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

我正在从 SKScene 转换。

Answer 1

要从另一个SKScene 呈现SKScene，您应该这样做：

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

您无需检索您的currentViewController，因为您始终可以访问您的scene 的view

正如下面的 cmets 所解释的，有多种方法可以调用实现到游戏 viewController 的函数，其中一种可能是创建一个 delegate/protocol，如下代码所示：

GameScene 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")
    }
}

GameViewController 示例：

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：
