应用程序关闭时保存NSInteger intScore

时间：2012-10-16 17:48:43

标签： iphone objective-c ios xcode cocoa-touch

我用xcode 4创建了一个应用程序，所有代码都在主代码文件中，所以我没有更多的类。 我有3个视图，但目前只使用一个。现在在游戏中我保存一个整数作为分数，并在游戏结束时显示你的分数是什么，但我想知道我如何让这个int出现在我的另外两个视图中的一个标签中，并且重启应用程序时如何将其保留在那里。我很抱歉我的英语不好，但我是这个目标C和iphone应用程序的新手。谢谢！

我怎么把东西放在其他的viewcontroller中，不能很好的代码文件

4 个答案:

答案 0 :(得分：3)

NSUserDefaults *scores = [NSUserDefaults standardUserDefaults];
if (_points>[scores integerForKey :@"highscore"]) {
    [_highScoresLabel setString:[NSString stringWithFormat:@"%d",_points]];
    [scores setInteger:_points forKey:@"highscore"];

我正在使用该代码在我的某个游戏中显示持续的高分。

在另一个UIViewController中显示只需添加此代码，其中_higScoreLabel是标签ypu，希望显示分数：

NSUserDefaults *scores = [NSUserDefaults standardUserDefaults];
NSString *_points = [scores integerForKey :@"highscore"];
[_highScoresLabel setString:[NSString stringWithFormat:@"%d",_points]];

答案 1 :(得分：0)

只要您知道用户的最终得分是什么，请将整数写入NSUserDefaults，如：

[[NSUserDefaults standardUserDefaults] setInteger:intScore forKey:@"score"];

然后，为了在另一个视图控制器中显示得分整数，您需要在另一个viewController的viewDidLoad中读取磁盘中的值，然后在标签中设置它！ 由于该值已存储在磁盘上，您甚至不需要将其作为参数传递或将其设置为另一个viewcontroller上的属性，只需从viewDidLoad中的NSUserDefaults读取它（或者您需要设置它的任何/ whereever方法） ）。

所以在第二个viewcontroller中，执行：

- (void) viewDidLoad {
    self.anotherLabel.text = [NSString stringWithFormat:@"%d", [defaults integerForKey:@"score"]];
}

答案 2 :(得分：0)

//要保存在pref中

int highScore  = yourGameScore;
[[NSUserDefaults standardUserDefaults] setObject:[NSNumber numberWithInt:highScore]     forKey:@"HighScore"];
[[NSUserDefaults standardUserDefaults] synchronize];

//从pref

获取保存的值 
int highScore = [[[NSUserDefaults standardUserDefaults] objectForKey:@"HighScore"] intValue ];

here is similar question in stack..

答案 3 :(得分：0)

Try using NSUserDefaults ,it will keep the value in memory until you forcefully remove it or you delete the app.

     int Score = HighScore;

    [[NSUserDefaults standardUserDefaults] setObject:Score forKey:@"anyKey"];

    currentScoreLabel.text = [NSString stringWithFormat:@"%d",Score];
    highScoreLabel.text=[NSString stringWithFormat:@"%d",[[NSUserDefaults standardUserDefaults] objectForKey:@"anyKey"]];
