How can I get Xcode 4.4.1 with OCMock + OCUnit to recognize my project's header files?

Question

I followed these steps: http://ocmock.org

and also these: http://twobitlabs.com/2011/06/adding-ocunit-to-an-existing-ios-project-with-xcode-4/

Though I could not successfully get step #4 of the twobitlabs instructions to work. meaining "Click the Build Settings tab and set the Bundle Loader setting to$(BUILT_PRODUCTS_DIR)/MyExistingApp.app/MyExistingApp"... When I did that, I get:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Yet, when I copy/paste that path in my terminal, it definitely is there.. as you can see here:

>ls -l /Users/patrick/Library/Developer/Xcode/DerivedData/Notes_and_Clefs-fpzvpdfkkkjuynefaqeajfdiznbp/Build/Products/Debug-iphonesimulator/Notes\ and\ Clefs.app/Notes\ and\ Clefs

So, I don't know if it's a problem with my file having spaces in it or not...

If I skip that step, when I run my tests, I get the infamous error:

Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_Question", referenced from:
      objc-class-ref in UnitTests.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Where the test.m file doesn't seem to understand what the header is for the actual class I am testing, despite my #import "Question.h" in the test.h's header... (also, adding it directly to the .m does nothing).

Answer 1

It occurred to me when closely looking at the stack trace.. ".../Debug-iphonesimulator/Notes\\ and\\ Clefs.app/Notes\\ and\\ Clefs\\""

the \\'s can't be good! I changed the Bundle Loader to the path without the backslashes, and now it works! Hooray!
