I believe the best answer to the question of "when to stop observing"
is "as soon as possible".
I was having trouble with a Core Data document (NSPersistentDocument)
observing too long, until I started cleaning things like this up in -
[NSDocumentController removeDocument:]. See typical code below.
You should also scroll down in your mailbox and read the thread which
was still active yesterday, "Re: Get error message about registered
observers when Object receives dealloc message". There is a good
discussion of this issue.
In the implementation of my subclassed NSDocumentController....
- (void)removeDocument:(NSDocument *)document {
// Remove observations by document's window controller
[[MAKVONotificationCenter defaultCenter] removeObserver:
[(Bkmslf*)document bkmslfWinCon]] ;
[[NSNotificationCenter defaultCenter] removeObserver:
[(Bkmslf*)document bkmslfWinCon]] ;
// Remove observations by document itself
[[NSNotificationCenter defaultCenter] removeObserver:document] ;
[[MAKVONotificationCenter defaultCenter] removeObserver:document] ;
[SSYMOCManager removeManagedObjectContext:[(Bkmslf*)document
managedObjectContext]] ;
[super removeDocument:document] ;
}
