Which one should I prefer for relasing my custom non-managed properties?

Question

-willTurnIntoFault or -didTurnIntoFault? I guess it's stupid to release properties in both of them, so I must choose one. Which is the best?

Answer 1

The former is invoked just BEFORE the object is turned into a fault, the latter just AFTER. What kind of custom non-managed properties are you referring to? The choice may depend on this.

Answer 2

The object is not "gone" when turned into a fault. It is reduced to its smallest size (just an empty object with an -objectID). If you are doing something in the -didTurnIntoFault that causes a property to be touched you would reverse the fault which is bad.

If your clean up requires touching a property you should do it in the -willTurnIntoFault. Otherwise it is pretty irrelevant which you choose.
