Is there an equivalent to [UIViewController viewDidAppear:] in Cocoa?
i.e., is there a way to get a delegate callback or notification when an NSView has appeared?
No.
NSViewControllerjust handles nib loading. (And we didn’t even have that until 10.5…) About the closest thing I know of is to override[NSView viewDidMoveToSuperview:]to send out appropriate messages.
