How to tell if a C++ symbol is #defined in Xcode

Question

I'm used to Visual C++ which makes it very clear in an #ifdef block if the block is going to be compiled or not.

Does Xcode (3) do this too, I couldn't see how?

What have you tried so far? This SO question might help you a bit... — Alexander Pavlov

@AlexanderPavlov: I think the OP is talking about the greying out that VS does for blocks that aren't currently applicable, not how to define symbols. — Ry-

@minitech Oh I see, thanks, now that makes more sense to me. — Alexander Pavlov

@minitech correct. Ideally not just visually but by hovering over and it telling me the value or something like that. — Mr. Boy

Have a look at the following screenshot.

As you can see, Xcode 4 does not apply syntax coloring in the parts that will not be compiled.

True but if your code doesn't have syntax coloring, it doesn't help... a function call with parameters and no literals or datatypes mentioned. However if I'm unsure, I suppose I can add a dummy line of code like int x = 123; and see what happens!
