ios - Swift SpriteKit 标签没有被删除

Question

我有 2 个标签，当玩家失败时添加；但是，重新启动游戏时，仍保留 1 个标签。我没有看到任何标签可能被意外复制的代码。

添加标签:

func getScores(x: SKScene) {

    //HighScore
    if currentScore > highScore
    {
        Defaults.setInteger(currentScore, forKey: "High Score")
        //High Score Particles
        //highScoreParticle()
    }

    //High Score
    highScoreLabel      = UILabel(frame: CGRect(x: x.frame.midX - 100 , y: x.frame.midY + 70, width: 200, height: 50))
    highScoreLabel.textAlignment = NSTextAlignment.Center
    highScoreLabel.text = "HighScore: \(Defaults.valueForKey("High Score")!)"
    highScoreLabel.font = UIFont(name: "Helvetica Neue UltraLight", size: 30)
    highScoreLabel.textColor = UIColor.whiteColor()
    x.view?.addSubview(highScoreLabel)

    //Current Score
    currentScoreLabel      = UILabel(frame: CGRect(x: x.frame.midX - 50 , y:  x.frame.midY, width: 100, height: 50))
    currentScoreLabel.textAlignment = NSTextAlignment.Center
    currentScoreLabel.text = "Score: \(currentScore)"
    currentScoreLabel.font = UIFont(name: "Helvetica Neue UltraLight", size: 30)
    currentScoreLabel.textColor = UIColor.whiteColor()
    x.view?.addSubview(currentScoreLabel)
}

删除标签:

func resetGame(scene: SKScene) {

    //Removes Labels
    startLabel.removeFromSuperview()
    currentScoreLabel.removeFromSuperview()
    highScoreLabel.removeFromSuperview()

    //Remove everything off scene
    scene.removeAllChildren()
    scene.removeAllActions()

    //Reset Variables
    currentScore = 0
}

highScoreLabel 不会从场景中删除

您正在将 UILabel 添加到场景 View Controller 。场景无法控制这一点。您需要创建一个 SKLabelNode 并使用 addChild

将其添加到场景中
