On another note, I'm reading about the Autorelease pool. Did I understand this correctly?

-(void)myFunc
{
 NSAutoreleasePool * myOwnPool = [[NSAutoreleasePool alloc] init];
 Obj o1 = [[Obj alloc] init];
 Obj o2 = [[Obj alloc] init]; 
 Obj o3 = [[Obj alloc] init];

 [whateverOtherObject setObj:o1]; //obj/setObj property set to retain
 [whateverObject setObj:o2 andObj:o3]; //obj/setObj property set to retain

 [myOwnPool release];
}

Would this automatically release o1, o2, o3 and still keep the memory allocated for "whateverOtherObject" and "whateverObject"?

Thanks!

No, because none of those objects were marked for autorelease. If you had done:

-(void)myFunc
{
 NSAutoreleasePool * myOwnPool = [[NSAutoreleasePool alloc] init];
 Obj o1 = [[[Obj alloc] init] autorelease];
 Obj o2 = [[[Obj alloc] init] autorelease]; 
 Obj o3 = [[[Obj alloc] init] autorelease];

 [whateverOtherObject setObj:o1]; //obj/setObj property set to retain
 [whateverObject setObj:o2 andObj:o3]; //obj/setObj property set to retain

 [myOwnPool release];
}

Then the only retains would be by whateverObject, and when it releases o1, o2, and o3, they would get deallocated.
