Cocoa NSVIew notification when presentation gets key focus?

Question

How can I get a notification if NSView receives key focus?

I was expecting a method like "windowDidBecomeKey" from NSWindow, but either I'm blind or there is nothing like NSView.

Answer 1

The key view, when it is, is the first responder. So, implement the methodbecomeFirstResponder in your view and either process it there, or send a notification to your controller to listen.
