I want to remove a notification observer and I am using the method:
removeObserver: name:@"myNotification" object:nil
You can remove an object from the notification center all together which means no notifications will get triggered. For example, when I have a view controller that has registered for notifications, I include this line in my dealloc.
[[NSNotificationCenter defaultCenter] removeObserver:self];
This is at the object level...so it will unregister for many notifications. It won't unregister for one notification in many objects.
Hope I understood your question correctly.
