Yep, stringWithUTF8String/UTF8String works well for std:string. I recommend
creating NSStringForStdString() and StdStringForNSString() utility
functions, and possibly an NSString category to add -stdStringValue.

What about the UTF8String method? It replaces the old lossyCString
method and should give you a pointer to a c string

An easy way of reference counting using Obj-C++ is to use the boost
libraries with boost::intrusive_ptr and these definitions:
// file.h
namespace boost
{
void intrusive_ptr_add_ref( id object );
void intrusive_ptr_release( id object );
}
// file.m
namespace boost
{

Wow. That is a really awesome trick there. Props to you!!
I wish Boost was easier to split apart so I didn't need to drag around
40MB of headers for just one feature…

Thanks for the input guys, I really appreciate the help.
I do have a lot of C++ code that I would like to use and put behind a
Cocoa front end, so I think that using Objective C++ classes as
wrapper classes around my C++ classes is the route I would like to take.
Anyone have an example of s
Without starting a religious war, I have to disagree with this.
ObjC++ is probably a bad idea if you are a novice programmer in general,
but I think it also has some really good things going for it, and having
written huge amounts of ObjC++ code, I think it's perfectly
straightforward to use.

You really don't. You think you do (probably because you know C++),
but then you enter the crazy messed up

Yes, I am. I have tried using both #include and #import, but neither
