Answer / Manish Kumar Prabhakar
NSNotification is a way to broadcast an event from one object to multiple objects, whereas a delegate is a specific object that handles certain tasks for another object. NSNotifications are typically used for more generic events, while delegates are used when there's a one-to-one relationship between the sending and receiving objects.
