This isn't how Objective-C++ works. Objective-C++ lets you include C++ and Objective-C code in the same module. You can send messages from C++ classes to Objective-C objects, and you can call C++ code from Objective-C methods. It does not unify the Objective-C and C++ class hierarchies. They are incompatible. Please read the "Using C++ with Objective-C" section of The Objective-C Programming Language guide: http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/ObjectiveC/Articles/ocCPlusPlus.html --Kyle Sluder _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
