iOS Core Data : memory leak ?

[namanhams]

I have googled around but i can not get the answer.

So i have 2 NSManagedObject class : A and B
A has a relationship with B, and B has an inverse relationship with A.
So in class A, the 'B' property is retain. And the same as in class B.

Class A :  
@property(nonatomic, retain) B *b;

class B :
@property(nonatomic, retain) A *a;

I have to do something like this in my code :

aObject.b = bObject;
bObject.a = aObject;

Then how can i release them ?

Have you tried something as simple as the inverse - like:

aObject.b = nil;
bObject.a = nil;
[aObject release];
[bObject release];

The @synthesized version of the property setter looks pretty much like:

-(void)getA:(ClassForA *)newA
{
    if (a) [a release];
    a = [newA retain];
}

so assigning nil results in a release to the retained object with nothing else getting retained (i.e., [nil retain]; doesn't really do anything).

You should set your properties to assign I think, otherwise you'll end up with a retain loop.
