But i have some problem to understand if I have to synchronize
both MOC manually or not and how? i mean, should i insert in the
main thread moc (using [moc1 insertObject:[moc1
objectWithID:objectId]]) the objects i inserted in the threaded
moc (ie moc2, using
insertNewObjectForEntityForName:inManagedObjectContext:) ? from
what i have read on this list, i have to synchronize mocs, nothing
is done for me.
From my test, to make the main thread array controller aware of
the new objects, i have to use insertObject: on the moc1.
reinserting an object in another context is an error, at the next
save: of the context, you'll get an error, the object is already
inserted blah blah blah.
So how can i make my array controllers aware of the newly inserted
objects ?
NSManagedObject implements:
- (NSManagedObjectID *)objectID;
NSManagedObjectContext implements:
- (NSManagedObject *)objectWithID:(NSManagedObjectID *)
objectID; // returns the object for the specified ID (the object
does not already need to be registered in the context, it might be
fetched or returned as a fault) - the object is assumed to exist as
described by the ID
Use the first to grab the object ID from your thread, use the second
to make the main event loop's MOC aware of the object.
Oh, and be very careful when working with threads. They can easily
be woven into a nice hangman's rope....
