Hi All, I have a view class that observes changes in a model class's array via KVO. Unfortunately - when ever the array is updated - the updates are sent to the view one at at a time.
In my model class I have the following line: NSMutableArray * eventsArrayProxy = [self mutableArrayValueForKey:@"events"]; [eventsArrayProxy addObjectsFromArray:appointments]; Which naturally causes the following method in my view class to be invoked: -(void) observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context My problem is that observeValueForKeyPath.. is invoked once for each and every single item in the appointments array (the array being added) - rather than once for all of them. Is this standard behavior? And is there a way to have it call observeValueForKeyPath.. one time for all the objects being added? In my case - I am sometimes adding as much as a thousand or more objects - so it is a severe performance issue right now. If this is the only way KVO works for arrays then I will have to find another way around it - but I'm hopeful perhaps there's some way this can be done.
