Question

我正在创建一个游戏，在那里我创建了一个如何玩游戏的教程页面。我只希望教程页面在他们第一次下载应用程序时显示。如果他们已经有应用程序，让他们直接去玩游戏。

这是我的教程代码：

 class TutorialPage: SKScene{


let playGameButton = SKLabelNode(fontNamed: "Helvetica")


override func didMove(to view: SKView) {





    // How to Play Title
    let tutorialLabel = SKLabelNode(fontNamed: "Helvetica")
    tutorialLabel.text = "How to Play"
    tutorialLabel.fontSize = 30
    tutorialLabel.fontColor = SKColor.pink
    tutorialLabel.position = CGPoint(x: self.size.width / 2, y: self.size.height * 0.75)
    tutorialLabel.zPosition = 1
    self.addChild(tutorialLabel)


    let movementLabel = SKLabelNode(fontNamed: "Helvetica")
    movementLabel.text = "Lorem Ipsum is a dummy text. 
    movementLabel.fontSize = 15
    movementLabel.fontColor = SKColor.blue
    movementLabel.position = CGPoint(x: self.size.width / 2, y: self.size.height * 0.65)
    movementLabel.zPosition = 1
    self.addChild(movementLabel)



    // PLay Game Button
    playGameButton.text = "Start Playing"
    playGameButton.fontSize = 25
    playGameButton.fontColor = SKColor.green
    playGameButton.position = CGPoint(x: self.size.width / 2, y: self.size.height * 0.2)
    playGameButton.zPosition = 1
    self.addChild(playGameButton)

}

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {

    for touch: AnyObject in touches{

        let pointOfTouch = touch.location(in: self)

        if playGameButton.contains(pointOfTouch){

            let sceneToMoveTo = GameScene(size: self.size)
            sceneToMoveTo.scaleMode = self.scaleMode
            let myTransition = SKTransition.doorsOpenHorizontal(withDuration: 1)
            self.view!.presentScene(sceneToMoveTo, transition: myTransition)

        }

    }

}






}

您需要保存像hasShownTutorial这样的变量：Bool = false。表示您是否已将它们显示在教程中，然后在显示教程后将变量保存到NSUserDefaults或pList。在启动时，您将加载该变量，如果它是假的，请向他们展示教程，如果是，则跳过教程。

如何在他们首次下载应用程序时才显示教程页面？ - SpriteKit
