Cannot figure out how to get rid of memory leak

Question

I'm trying to test for memory leaks in my iphone and I'm not having much luck getting rid of this one. Here is the code that is leaking.

- (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;
}

It is leaking on the self.settingsManager = [[VacaCalcSettingsManager alloc] initWithManagedObjectContext:self.moc]; line.

The self.settingManager instance variable is released in the dealloc method of the class.

I'm not sure what other information would be pertinent. Please let me know and I can provide it.

Thanks for any assistance.

Here is the header file.

@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;

If your settingsManager property is set to retain then you are retaining an object twice with the line: self.settingsManager = [[VacaCalcSettingsManager alloc] initWithManagedObjectContext:self.moc];

Try adding autorelease to the alloc]init or creating a class method on VacaCalcSettingsManager that returns an autoreleased object. Otherwise you could redeclare your property with assign so that it does not retain the object a second time.
