Dear list,
I've been digging around for export and import strategies to allow me
to export parts of a core data model. In more detail, I have a set of
categories, each of which contains a set of meetings. Each meeting has
a fairly complex object graph below it (agenda, agenda items,
location, title, etc). I want to allow the user to export a meeting
which can then be imported by someone else using the same application.
Does anyone have any good advice how best to approach this? I was
considering making the NSManagedObject subclasses conform to NSCoding,
but I read in a couple of places that this was difficult to do,
particularly the initWithCoder: part. Anyone tried this already?
Many thanks,
Martin
