Starting with 10.10, -[NSView setNextResponder:] forwards to the view controller, which is what you are seeing. From the AppKit Release Notes <https://developer.apple.com/library/mac/releasenotes/AppKit/RN-AppKitOlderNotes/#10_10ViewController>: NSViewController automatically adds itself into the responder chain... When the view has a call to setNextResponder: made, the method will be forwarded to the view’s view controller. If you currently are already doing your own responder chain management, take particular care as the view.nextResponder may already be the NSViewController. This can cause an issue for apps that manually set the viewController.nextResponder = view.nextResponder, without checking to see if the view.nextResponder != viewController... It sounds like in your case you may want to implement responder methods higher up in the chain that, when appropriate, dispatch messages to the view controller(s), but this of course will depend on your architecture and what exactly you are trying to do. -Conrad _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
