That is fine with me. Good luck with the book.

Tom, I’m writing a chapter on custom controls in the forthcoming “More Cocoa Programming for Mac OS X”, and I used this code as a starting point for making a control bindable. In the end, my code looks a lot like yours. Is this OK with you?

If you have access, you might want to take a look at the Cocoa Tips & Tricks session video from WWDC 2008. That talk covers this technique.

I’ve been doing something pretty similar but I hadn’t broken it out into a category. This is a great post and incredibly useful if you’ve been struggling with implementing custom bindings.

Thanks Peter. I’ve made those two changes.

I have a couple of minor suggestions: Use NSParameterAssert instead of that if-then-NSLog block at the top. This way, you get an exception that you can break on. Use __PRETTY_FUNCTION__ (which is a C string) instead of NSStringFromSelector(_cmd). This way, the class name is included. Not too helpful in this case, since you're categorying onto NSObject; it's most useful when you have logging statements in the same method in two or more classes. With those out of the way: Excellent work. It's nice to have this Bindings mystery solved. Thank you.
