Where to include header files - relates to last question on variable scope


I've created a singleton class or however one might phrase that ;-)

My idea was that I include the header file for this (extensively used) class
in 'main.m' and have it available to all other classes in my program.

...so much for that idea...

Why do I have to include the header file of this singleton class in every
other class I use it in? Should the class not be available to the compiler
the moment it's included in the 'main.m'?

I'm missing something fundamental here - it's always like that :-)

Could somebody please give this blind puppy a nudge in the right direction?



Ole.
