Is iOS NSNotification equivalent to Events?

Question

Is iOS NSNotification equivalent to Events in other systems? Contrary to sending message is it really non blocking the sender process ?

Yes, but the difference is you have a single instance of NSNotificationCenter, which broadcasts a NSNotification that can be caught application wide, unlike .net for example, where you declare a public event in your class and can subscribe for it only if you have an instance of this class. And yes it's not blocking the sender process. — graver, Apr 19 '12 at 06:57

NSNotification objects encapsulate information so that it can be broadcast to other objects by an NSNotificationCenter object.
