To raise an event:

[[NSNotificationCenter defaultCenter] postNotificationName:notificationName object:someObj];

To listen for the event:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(notificationSelector:) name:notificationName object:notificationSender];

To stop listening for the event:

[[NSNotificationCenter defaultCenter] removeObserver:self name:notificationName object:notificationSender];
