Oh, right. I've heard about this, but only as "reference counting", not the
term ARC. Personally, I wouldn't mind using it, if it saves me the trouble
of having to release objects by myself.
Objective-C pointer variables hold either owning or non-owning references.

Thanks for clarifying that.

Well, what I usually do is declare my properties with @synthesize,
initialize them by either calling [[alloc] init] or connecting them to
visual objects in XCode's Interface Builder. The book I read on this also
taught me to call -release for every property on the class's -dealloc
method. Is this wrong?
I think I'm also gonna take the time to read up on Obj-C memory management,
to better get a grasp on it :)
Sincerely,
Omar
