NSResponder is a class used in Mac Development. NSResponder is an abstract class that forms the basis of event and command processing in the Application Kit. The core classes—NSApplication, NSWindow, and NSView—inherit from NSResponder, as must any class that handles events. The responder model is built around three components: event messages, action messages, and the responder chain.
