NSView Implements basic drawing, event handling and printing behaviors for applications. Usually application code define subclasses of NSView to provide richer implementations. Belongs to the Foundation framework for Cocoa and Cocoa Touch.
The NSView class defines the basic drawing, event-handling, and printing architecture of an app. You typically do not use NSView objects directly. Instead, you use objects whose classes descend from NSView or you subclass NSView yourself and override its methods to implement the behavior you need. For any view object, there are many methods that you can use as-is.
