我已经在Xcode中创建了一个游戏，但是当玩家输了时，我想在屏幕上切换到游戏，此时main.storyboard文件是空白的。我找到了这个解决方案Using a view controller for a game over scene
但是，我不确定如何在我的代码中实现它。我在下面附上了我的代码，如果有人能帮助我，我将非常感激。

您应该设置GameOverScene并在需要时显示此场景。 RayWenderlich网站有很多教程可以告诉你如何做到这一点，这里可能解释得太多了
以下是Apple Game Frameworks Section
的链接This page向您展示了如何实现级别完整叠加）
但基本上你只是创建一个新场景，向它添加你需要的任何UI元素，然后从视图控制器你可以调用PresentScene，就像这样
view.presentScene(scene)
示例代码：
class GameScene: SKScene {
var notificationLabel = SKLabelNode(text: "Tap the screen to win")
override func didMove(to view: SKView) {
self.backgroundColor = SKColor.black
addChild(notificationLabel)
notificationLabel.fontSize = 32.0
notificationLabel.color = SKColor.white
notificationLabel.fontName = "Thonburi-Bold"
notificationLabel.position = CGPoint(x: size.width / 2, y: size.height / 2)
}
func displayGameOver() {
let gameOverScene = GameOverScene(size: size)
gameOverScene.scaleMode = scaleMode
let reveal = SKTransition.flipHorizontal(withDuration: 0.5)
view?.presentScene(gameOverScene, transition: reveal)
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
displayGameOver()
}
}
class GameOverScene: SKScene {
var notificationLabel = SKLabelNode(text: "You Won")
override init(size: CGSize) {
super.init(size: size)
self.backgroundColor = SKColor.darkGray
addChild(notificationLabel)
notificationLabel.fontSize = 32.0
notificationLabel.color = SKColor.white
notificationLabel.fontName = "Thonburi-Bold"
notificationLabel.position = CGPoint(x: size.width / 2, y: size.height / 2)
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
let gameScene = GameScene(size: size)
gameScene.scaleMode = scaleMode
let reveal = SKTransition.flipHorizontal(withDuration: 0.5)
view?.presentScene(gameScene, transition: reveal)
}
}
点击任一场景中的屏幕将显示另一个场景。你也应该能够通过viewcontroller来管理它，并做同样的事情，但我还没有这样做，我自己还是很新的SpriteKit。
希望这有帮助
