NSMutableArray内存泄漏问题

Question

我正在处理简单的iPhone游戏。当游戏结束时，我试图将一些分数信息保存到.plist文件。你能帮我理解我做错了什么吗？

这里是 “完成” 的游戏方法：

- (void) gameDone { 

    // something .... 

// save our current score values 
NSDictionary *currentScore = [[NSDictionary alloc] initWithObjectsAndKeys:[NSNumber numberWithInt:[score getScoreValue]], @"score", [NSNumber numberWithFloat:[time getSeconds]], @"time", nil]; 
[score saveValueToFile:currentScore toFile:fileName]; 
[currentScore release]; 

// something .... 

}

这里是2种方法从我的其他类保存一个分数：

- (NSMutableArray *) loadFromFile:(NSString *) fileName { 
{ 
    // get a paths 
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentsDirectory = [paths objectAtIndex:0]; 
    NSString *plistPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.plist", fileName]]; 

    NSMutableArray *scoreTable = [NSMutableArray arrayWithContentsOfFile:plistPath]; 

    return scoreTable; 
} 


// save a score table to plist file 
- (void) saveValueToFile:(NSDictionary *)value toFile:(NSString *)fileName { 

    // load all score table 
    NSMutableArray *scoreTable; 
    scoreTable = [self loadFromFile:fileName]; 

    // insert new value 
     // [MEMORY_LEAKS_LINE] ATTENTION: Instrument > Memory Leaks point to this line 
    [scoreTable insertObject:value atIndex:[scoreTable count]]; 

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentsDirectory = [paths objectAtIndex:0]; 
    NSString *path = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.plist", fileName]]; 

    [scoreTable writeToFile:path atomically:YES]; 
    [scoreTable release]; 
} 

当我启动新游戏（实际上我的游戏设计有可能连续玩许多游戏）内存泄漏仪器总是添加32个字节到总泄漏字节并链接到[MEMORY_LEAKS_LINE]

我认为我的问题可能与currentScore值。但是我在这里的示例代码的第一部分发布它。

我在做什么错了？

我不知道有关的泄漏，但是你在做“scoreTable释放”，但你的scoreTable已经在自动释放模式（你叫[NSMutableArray的arrayWithContentsOfFile：plistPath]），所以它不会保留
