OK thats cool. My #include <iostream> is in a .h file. Just to
clarify do I need to make the .h file a .mm?
Thanks.

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.

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
