To make a somewhat long story short, I’m trying to do this:

#define MY_MACRO(x) id myObjectx;

to create myObject1 and myObject2 and so on. I have a lot of these, and the real situation is a little more complicated than just declaring the object and that’s it, I need it to repeat a few different things with that number, and copy-paste is getting ugly.

Note: I understand that with the information I’ve given you you’ll be tempted to suggest I just use an array, so I’ll explain – I need a bunch of separate KVO properties, and they can’t all go in a to-many because the amount of change notifications would get out of hand.

    As bmargulies said, you can use ## in the macro:

    #define MY_MACRO(x) id myObject##x;

    bmargulies, why don’t you add your comment as an answer…?
