EXC_BAD_ACCESS - iPhone

Question

我的iPhone應用程序崩潰，並使用此代碼時收到EXC_BAD_ACCESS錯誤：

NSError *error; 
     NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); //1 
     NSString *documentsDirectory = [paths objectAtIndex:0]; //2 
     NSString *path = [documentsDirectory stringByAppendingPathComponent:@"stats.plist"]; //3 

     NSFileManager *fileManager = [NSFileManager defaultManager]; 

     if (![fileManager fileExistsAtPath: path]) //4 
     { 
      NSString *bundle = [[NSBundle mainBundle] pathForResource:@"stats" ofType:@"plist"]; //5 

      [fileManager copyItemAtPath:bundle toPath: path error:&error]; //6 
      [bundle release]; 
     } 

     NSMutableDictionary *savedStock = [[NSMutableDictionary alloc] initWithContentsOfFile: path]; 

     //load from savedStock example int value 
     score.highScore = [[savedStock objectForKey:@"score"] intValue]; 
     score.deaths = [[savedStock objectForKey:@"deaths"] intValue]; 
     score.iFallPoints = [[savedStock objectForKey:@"iFallPoints"] intValue]; 
     score.difficulty = [[savedStock objectForKey:@"difficulty"] intValue]; 

     [savedStock release]; 

得分是我訪問的單身。

您沒有分配或保留包;不要釋放它。

如果您需要幫助理解，請參閱memory management programming guide。

此外，靜態分析器可以幫助指出一些內存錯誤。
