Objective C adding C++

Question

I have been given some C++ classes to incorporate into my Objective C project. I've never done this before, so I have to ask:

1. Is there something special I need to do or can I just rename the .cpp to .mm?
2. What about importing (or including) the .h file? Anything special I need to do there?

Just baby steps here. Thank you.

Answer 1

Remember how the C build model works; It is the Objective-C files including C++ headers that must be switched over to Objective-C++.

Answer 2

See my answer to this question. Basically, the .mm convention is a nicety, not a necessity. If you use the File Inspector to set up the file types of the .h\.m\.cpp files correctly, you can get Objective-C to play nicely with C++ files without difficulty.
