SpriteKit中带有Swift的presentScene上的黑屏

Question

I am new to Swift and SpriteKit, so not sure if I'm handling the different screens and scenes right..

On this screen you can select levels:

class GameScene : SKScene

        let reveal = SKTransition.crossFadeWithDuration(0.4)
        let nextScene = Level_018(size: CGSize(width: 1050, height: 770))
        self.view?.presentScene(nextScene, transition: reveal)

I you can select Level_018, and when you have completed level 18 I present another SKScene.

class Level_018 : SKScene

    let reveal = SKTransition.crossFadeWithDuration(0.8)
    let scene = GameComplete(size: CGSize(width: 1050, height: 770))
    self.view?.presentScene(scene, transition: reveal)

This works

class GameComplete : SKScene

    let reveal = SKTransition.crossFadeWithDuration(0.8)
    let scene = GameScene(size: CGSize(width: 1050, height: 770))
    self.view?.presentScene(scene, transition: reveal)

But here, when I try to present the GameScene that I stared with, I only get a black screen for some reason..

可以通过创建新的LevelSelect：SkScene类来修复它。
