推荐答案
有一个不错的 在 CocoaWithLove.com 上找到的教程.
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".并且执行这两个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.
