Hi all, have a Core Data document based application which uses modal
sheets as a way for the user to edit the document's data. What is the
best way to give the sheet the ability to operate on a copy of the
data with the parents sheet's undo context? And how best to merge
these changes with the main document context.
I've thought of having a unique MOC for each sheet, and then posting a
custom notification that would in turn cause each MOC to perform
something like:
for (id object in [managedObjectContext registeredObjects]) {
[managedObjectContext refreshObject:object
mergeChanges:YES];
}
Does this way make any sense? Is there a better way to do this that
I'm missing?
Thanks for any pointers!
Kevin
