Basically, CFTypes are not natively archivable. Neither are they "found" by valueForKey:, so -valueForUndefinedKey: is called. I then have to re-find the property myself by implementing the same search algorithm that KVC uses, detect the CFType of the object and call a function (different for each kind) that will wrap or convert the CFType with something that is archivable, or usable by an observer using KVO to observe changes to these properties. I also have to override -valueForUndefinedKey: and do this in every object that has properties that are CFTypes. My question really is if this is necessary or is there a more cunning, generic way to handle this? --Graham _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
