Details:
Looking at the implementation of NSKeyValueObserving.m
(lines 1816, 1846)
.. willChangeValueForKey: (NSString*)aKey
withSetMutation: (NSKeyValueSetMutationKind)mutationKind
usingObjects:(NSSet*)objects
and
... didChangeValueForKey: (NSString*)aKey
withSetMutation: (NSKeyValueSetMutationKind)mutationKind
usingObjects: (NSSet*)objects
I notice that the NSSet* object parameter is not being used, but instead the
property 'aKey' is being requested each time.
Should this implementation not use the passed NSSet* of objects when deciding
on the delta to report to the observers?
I have code running on OSX Lion that appears to do this, and from the function
signatures I expect that's the intended behaviour.
