加載，在第二個視圖控制器上保存高分

Question

我想加載並保存我的高分只在gameOverViewController。我已成功將secondViewController的分數轉移到gameOverViewController。 gameOverViewController就像屏幕上的普通遊戲一樣，顯示你的分數，高分，並有重試和主菜單按鈕。我試圖設置highScoreLabel等於scoreGameOverLabel，它運行，但highScore int保持在0並且不等於gameOverScore。我想：

1. 如果評分>高分，高分=得分

2. 如果分數<高分，高分仍相同

   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中，嘗試設置您的最後一個分數。

gameOver.lastScore = addOne 

在GameOverViewController添加lastScore變量，並跟蹤您的高分。

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 

或許應該

highScoreLabel.text = scoreGameOverLabel.text 

其次，按您的片斷，在GameOverViewController沒有addOne，你怎麼設置它並使用它來比較。如果條件？
