That is essentially quite similar to the beginning code. But how do you 
split this in different files?

I ended up implementing David's version which actually works (thanks David).
The only thing which I don't like about that version is that the 
different files are "included" in a class implementation file (.m) and 
not explicitly in the makefile. I essentially tried to do the same 
thing, but with explicit separation of headers and of course it didn't work.
If such a project had to be managed in ProjectCenter it wouldn't work, 
for example: project files are added automatically to the make file. I 
checked and "make dist" works, but it still might pose problems when 
distribution make package lists.

I still have stuff to improve, but for now I like the first clean-up, it 
made the code (and also the necessary imports) much much better. The 
only dirty part is actually my linux code which has tons of ivars.
