I know this has been discussed ad-nauseum but I just don't get some of the memory management. I understand that retain keeps the object alive and copy gives one a separate copy of an object. What I don't get is when it comes to ivars & properties, retain as a property means that the setter releases the old value & retains the new: prop...

Second, I want to pass objects to updateTheValue() like strings, but mostly int...
