在第二个视图控制器上加载、保存高分

Question

我正在尝试仅在 gameOverViewController 上加载和保存我的高分。我已经成功地将分数从 secondViewController 转移到了 gameOverViewController。 gameOverViewController 就像一个普通的游戏结束屏幕，显示你的分数、高分，并有重试和主菜单按钮。我试图将 highScoreLabel 设置为 scoreGameOverLabel，它运行，但 highScore int 保持在 0 并且不等于 gameOverScore。我正在尝试：

1. if score > high score , high score = score

2. 如果分数

   var addOne = 0
   class SecondViewController: UIViewController
   {
   
   @IBOutlet weak var score: UITextField!
   
   score.text = "\(addOne)"
   
   override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
   
   let gameOver = segue.destination as! GameOverViewController
   
   gameOver.gameOverText = score.text!
   gameOver.lastScore = addOne
   }
   

gameOverViewController

class GameOverViewController: UIViewController {


@IBAction func retryButton(_ sender: Any) {   
addOne = 0
  highScoreLabel.text = NSString(format: "%i", highScore) as String
} 

@IBAction func mainMenuButton(_ sender: Any) { 
addOne = 0
  highScoreLabel.text = NSString(format: "%i", highScore) as String
}        

var lastScore = 0
var highScore = UserDefaults.standard.integer(forKey: "high_score")  

@IBOutlet weak var highScoreLabel: UILabel!

@IBOutlet weak var scoreGameOverLabel: UILabel!

var gameOver = ""

override func viewDidLoad() {
    super.viewDidLoad()

    if lastScore > highScore {
        highScore = lastScore
       highScoreLabel.text = NSString(format: "%i", highScore) as String
        UserDefaults.standard.set(highScore, forKey: "high_score")
    }                 
    scoreGameOverLabel.text = gameOver       
}

Answer 1

在SecondViewController，尝试设置你的最后得分。

gameOver.lastScore = addOne

在GameOverViewController 中添加lastScore 变量并跟踪您的高分。

var lastScore = 0
var highScore = UserDefaults.standard.integer(forKey: "high_score")

if lastScore > highScore {
    highScore = lastScore
    UserDefaults.standard.set(highScore, forKey: "high_score")
}

Answer 2

首先，

highScoreLabel = scoreGameOverLabel

应该是

 highScoreLabel.text = scoreGameOverLabel.text

其次，根据你的sn-p，在GameOverViewController中没有addOne，你是如何设置它并在If条件下使用它来比较的？
