How to integrate KVC in MVC?
- by Paperflyer
So I have an MVC-application in Cocoa.
There are some custom views, a controller and a model. Of course, the views need to know some stuff, so they get their data from the controller. However, they do not use accessors in the controller, they use KVC with a keypath that calls right through to the model:
// In view.m
time = [timeSource valueForKeyPath:@"theModel.currentTime"];
// timeSource is a pseudo-delegate of the view that holds the controller
This simplifies things a great deal and technically, the views still don't know the model in person (that is, in pointer). But of course, they access it directly.
Is that a usual (or at least sensible) usage of KVC and MVC?
Or how would you implement this kind of communication?
