每次玩家退出应用程序时，我都会尝试获得高分以保存，但我很难让它发挥作用，而且我很困惑我在哪里犯了错误。

var gameSettings = Settings.sharedInstance
let HIGHSCORE = "HIGHSCORE"

if gameSettings.highScore < score{
        gameSettings.highScore = score

        UserDefaults.standard.set(gameSettings.highScore, forKey: HIGHSCORE)
    }

        if gameSettings.highScore >= score{
            gameSettings.score = score

    }

    let gameOverHighScore = SKLabelNode()
    gameOverHighScore.name = "gameOverHighScore"
    gameOverHighScore.fontName = "Helvetica Neue UltraLight"
    if let HIGHSCORE = UserDefaults.standard.value(forKey: HIGHSCORE) {
        gameOverHighScore.text = "HIGHSCORE : \(HIGHSCORE)M"
    }
    gameOverHighScore.fontColor = SKColor.white
    gameOverHighScore.position = CGPoint(x: 0, y: -175)
    gameOverHighScore.fontSize = 70
    gameOverHighScore.zPosition = 52
    addChild(gameOverHighScore)

这是一个有关如何执行此操作的简单示例：

let firebaseId = user.uid // Variable we want to save
UserDefaults.standard.set(firebase, forKey: "firebase") // Saving the variable with key "firebase"

现在要检索：

if let firebaseId = UserDefaults.standard.string(forKey: "firebase") {
    print("Firebase ID: \(firebase)")
}

在您的代码中，您正在检索到 HIGHSCORE，并且您应该检索到类似 gameSettings.highScore 的内容（基于我可以从您的代码中推断出的内容）

在if let HIGHSCORE = UserDefaults.standard.value(forKey: HIGHSCORE) { gameOverHighScore.text = "HIGHSCORE : \(HIGHSCORE)M" }

您尝试在 UserDefaults 中查找值，而不是通过键 HIGHSCORE，而是通过 ANY 类型的新值 HIGHSCORE。如果你想修复它，你可以这样做：

if let HIGHSCORE = UserDefaults.standard.value(forKey: self. self.HIGHSCORE) as! Int { gameOverHighScore.text = "HIGHSCORE : \(HIGHSCORE)M" }

或者你可以用另一个名字解开新值中的值。并且不要忘记将值转换为适当的类型或使用

UserDefaults.standard.integer(forKey: self.HIGHSCORE)
