| This is a very good intro to a complex subject. I just wish the article were longer. Retain vs copy might be a good subject for a follow-up piece. | ||

Really good treatment

Here's a simple guide for retain or copy. Use retain when the object represents a relationship. Use copy when the object represents a value. The difference is this: in a relationship, if the object pointed to changes, you want your variable to reflect this change of state; whereas, with a value, you want the value to remain unaltered if the original object changes unless you explicitly alter your copy.
