Well, I wonder if starting private properties with a p as in pSomeAwesomeThing would be a decent-enough convention to start, because then an ivar for a private property would be _pSomeAwesomeThing. This would leave public properties without any lowercase p (followed by a capital letter that starts the next word) and the ivar would be the same, but just starting with the _. That would give us: Public property: labelString Public property's ivar: _labelString Private property: pLabelString Private property's ivar: _pLabelString Does this seem to be a decent enough and not unweildy convention? While it wouldn't show any difference between a local or a parameter, it would certainly clarify the scope of these 4 cases. Is this enough, or should we also take into effect locals and parameters? For locals, we could use my as a prefix since they would be local to the method, but that could end up as a PITA. Also, how would this conflict with the recommended is prefix for booleans, if at all?
