I have a XCode4 / iOS project with a regular target and unit test target. Everything works fine, except when I try to #import one of my classes in my test class and try to use it. If I try to build the unit test target, I get the following link error:

Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_FRRCategory", referenced from:
      objc-class-ref in CategoryTests.o
ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status

In CategoryTests.m I'm importing the header file in this way:

#import "../todoro/FRRCategory.h"

What am I doing wrong?

Follow the instructions here. It doesn't require you to add any files to compile sources.

I first missed that "Symbols Hidden by Default=NO" should be for your app target, not test target.

It worked for me anyway (tm).
