This invokes the default implementation of - bind:toObject:withKeyPath:options:, which takes care of the model -> view communication. You now need to take care of the view -> model communication. As described in the User Updates a Value in the User Interface section of the Cocoa Bindings Programming Topics, you can call -setValue:forKeyPath: on the toObject and withKeyPath arguments of the original binding (you can get this information by calling - infoForBinding). Or you might have some custom logic that informs the controller/model of the change in a different way.

When the view changes num, it need to push the change to the bound model objects.

See mmalc’s Graphics Bindings sample:

Sometimes Cocoa can be overwhelming. This will help. Thank you so much. :)
