Since one can use C++ libraries in Objective-C also, there's actually no need to create special Objective-C header files.

Box2D for example is a pure C++ physics engine but is used in a lot of games, even ones written in Objective-C.

The only caveat (for developers using your library) is that

you still need to instruct the compiler to build all files that use C++ headers as Objective-C++ rather than Objective-C.
