Any file that #includes <iostream>, either directly or indirectly via
another header, needs to be a .cpp or .mm in order to work. .c or .m
will not work.

Thanks both to Dave and John,
I am using .mm for my implementation files but it is in the .h files i
am having problems. Do I need to put the entire class, including
deceleration in an .mm file?
Thanks guys.
Phil

I am trying to write using Objective-C++. I have read the docs and
understand what I can and can't do with it but I have a really basic
problem. When I put #include <iostream> in my header files I get an
error saying that the file cannot be found? Why is this?
Most likely because the compiler doesn't think that it's compiling an
objective-c++ file, which means that it isn't using the C++ header
search paths. What extension are you using for your filename? You have
to use .mm to tell the compiler that it's objective-c++.
Also when creating the file, do I create a C++ file or an Obj-C file
or doesn't it matter?
It should be a .mm file.
Finally, I want to do some thing like this
#ifdef _MAC_OS_X
//do some obj-c code
#endif
#ifdef _WIN32
//use WIN32 API coding
#endif
#ifdef __OBJC__
//objc only stuff
#endif
