推荐答案

有一个不错的可在CocoaWithLove.com 找到的教程.

There's a nice tutorial found at CocoaWithLove.com.

总结:您将创建NSView的子类(例如"EugeneView")，然后该子类中将包含一些额外的方法，例如"setNextResponder"和"setViewController".并且执行这两种方法应该可以将您的NSViewController集成到响应者链中.

Summed up: you'll create a subclass of NSView (e.g. "EugeneView") and then that subclass will have some extra methods in it, such as "setNextResponder" and "setViewController". And doing these two methods should get your NSViewController integrated into the responder chain.
