Looks like I’m about a week behind in my Late Night Cocoa<\/a> listening. I finally caught up with the episode on NSResponder<\/a>, featuring Aaron Hillegass<\/a> of Big Nerd Ranch<\/a>.<\/p>\n

Scotty is doing such a fantastic job with all the podcasts, I shouldn’t be surprised that this one was also excellent. I really like the way he pulls information out of his guests in a way that makes the shows engaging for both experienced and (I assume!) newbie Cocoa developers alike.<\/p>\n

This episode in particular is a must-listen for Cocoa developers who aren’t completely comfortable<\/em> with the responder chain. In particular, I like the way Aaron comes right out and declares the "First Responder" proxy icon in Interface Builder to be "a lie." In my travels I’ve found that "First Responder" is a woefully misunderstand concept.<\/p>\n

Mostly the material in the show was a recap for me, but one concept I had never considered was that of a "view controller" that is inserted directly into the responder chain. Whoah, nifty! Aaron referred specifically to the MOViewController from the MOKit<\/a> open source framework, by Mike Ferris<\/a>. The idea is instead of subclassing a view to be able to get at all of its NSResponder-oriented behaviors, why not just insert an object immediately before it in the chain? Now you can respond to whatever want to (Aaron uses the example of a delete key for NSTableView), and pass the rest of the events through to the view.<\/p>\n

Great stuff. Thanks Scotty & Aaron for an entertaining and educational show.<\/p>\n","protected":false},"excerpt":{"rendered":"
