Question

我的HighScore存在问题。当我运行应用程序时，我可以在HighScore标签中看到我的HighScore，但是当我退出我的应用程序并重新启动它时，HighScore消失了......有人可以告诉我什么是错的吗？

这是我的.h文件：

#import <UIKit/UIKit.h>
#import <AudioToolbox/AudioToolbox.h>

int Y;
BOOL Start;
BOOL applications;
int RandomPosition;
int Scorenumber;
int HighScore;

@interface ViewController : UIViewController

{


SystemSoundID SoundId;


IBOutlet UILabel *Intro1;
IBOutlet UILabel *Intro2;
IBOutlet UILabel *Intro3;

IBOutlet UIImageView *Heli;

NSTimer *timer;



IBOutlet UIImageView *Obstacle;
IBOutlet UIImageView *Obstacle2;
IBOutlet UIImageView *Obstacle3;
IBOutlet UIImageView *Obstacle4;
IBOutlet UIImageView *Obstacle5;
IBOutlet UIImageView *Obstacle6;
IBOutlet UIImageView *Obstacle7;
IBOutlet UIImageView *Obstacle8;
IBOutlet UIImageView *Obstacle9;
IBOutlet UIImageView *Bottom1;
IBOutlet UIImageView *Bottom2;
IBOutlet UIImageView *Top2;
IBOutlet UIImageView *Top1;
IBOutlet UIImageView *corona;

IBOutlet UILabel *Score;

NSTimer *Scorer;



}

这是我的.m文件：

#import "ViewController.h"

@interface ViewController ()

如果有人可以回答这个问题真有帮助:) 我和它坐在一起后，我有点厌倦了！

Answer 1

使用密钥将您的高分放入NSUserDefaults：

forKey:@"HighScoreSaved"];

但是你试图用以下方法解决这个问题：

objectForKey:@"HighScore"]

您的密钥在两个地方都必须相同。或者换句话说，您必须使用相同的密钥写入和读取NSUserDefaults。

如果我重新启动我的应用程序，则无法看到HighScore
