无法弄清楚如何摆脱内存泄漏

Question

我正试图测试我的iPhone中的内存泄漏,我没有太多运气摆脱这个.这是泄漏的代码.

- (id)initWithManagedObjectContext:(NSManagedObjectContext *)aMoc delegate:(id)aDelegate runSync:(BOOL)aRunSync {
    if (self = [super init]) {
        self.moc = aMoc;
        self.settingsManager = [[VacaCalcSettingsManager alloc] initWithManagedObjectContext:self.moc];
        self.delegate = aDelegate;
        calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
        self.runSync = aRunSync;
    }

    return self;
}

它正在泄漏self.settingsManager = [[VacaCalcSettingsManager alloc] initWithManagedObjectContext:self.moc];.

self.settingManager实例变量在类的dealloc方法中释放.

我不确定其他相关信息是什么.请告诉我,我可以提供.

谢谢你的帮助.

这是头文件.

@interface VacaCalcCalculation : NSObject {
    NSManagedObjectContext *moc;
    VacaCalcSettingsManager *settingsManager;
    id delegate;
    NSCalendar *calendar;
    NSDate *nextBankLimitDate;
    BOOL runSync;
}

@property (nonatomic, retain) NSManagedObjectContext *moc;
@property (nonatomic, retain) VacaCalcSettingsManager *settingsManager;
@property (nonatomic, retain) id delegate;
@property (nonatomic, retain) NSCalendar *calendar;
@property (nonatomic, retain) NSDate *nextBankLimitDate;
@property (nonatomic) BOOL runSync;

- (id)initWithManagedObjectContext:(NSManagedObjectContext *)aMoc delegate:(id)aDelegate;

如果您的settingsManager属性设置为,retain那么您将使用该行保留一个对象两次:self.settingsManager = [[VacaCalcSettingsManager alloc] initWithManagedObjectContext:self.moc];

尝试添加autorelease到alloc]init或创建上VacaCalcSettingsManager一类方法,它返回一个autoreleased对象.否则,您可以重新声明您的财产,assign以便它不会再次保留该对象.
