I would just add (perhaps unnecessarily) that on iOS, where KVC is used, one
should not be tempted to use a pure ivar instead of property + synthesized
accessor, because when KVC sets an ivar directly it retains it and your whole
memory management scheme can be thrown off. (This is just one of many reasons
why direct KVC access to ivars is scary.) The property, with its declared
memory management policy, and the synthesized accessor that implements that
policy, acts as a memory management gateway to ward off KVC's curious and
probably unwanted memory management behavior.
I don't remember whether there are similar memory management considerations on
OS X, but presumably not. m.
