If one searches for mixing objective-c and c++ this link invariably comes up as THE solution.
Unfortunately it’s dead. Does anyone know where this article has moved, have an alternative article, or have some code demonstrating two way chatter between objective-c and c++ objects (calling both from the other). I can architect around an inability to call objective-c from c++, but I would much prefer to have the freedom to perform callbacks.
I have gotten as far as instantiating a c++ object and calling methods on it from objective-c++, but I haven’t been able to figure out how to get the c++ to call back or how to properly declare the c++ object in the objective-c++ object’s header file.
The article is still available on the WayBack Machine (
