Hi,
I have an app that uses UIDocument and NSUndoManager. That way the system
picks up changes to the data and knows when to auto-save.
Some parts of the model are not using the undo manager (mostly settings where
undo makes no sense or isn't wanted). Still that data is stored alongside the
main data.
What I want is that iOS saves whenever the app is backgrounded.
So the questions is: Can I safely call -updateChangeCount: when my app is being
sent to the background alongside the automatic NSUndoManager change handling?
It seems to work quite nicely (when called from the app delegate's
-applicationWillResignActive:), but I'm not sure if that's just an illusion and
there's trouble waiting down the road.
Any thoughts?
Regards
Markus
