Example project wont build when path has space in it

[richardgroves]

If you clone the repo into a path that has a space in it, the follow the instructions for building the Example project it will fail to build.

The error appears to be the expansion of the $(SOURCE_ROOT) variable into the Preprocessor macro value for FB_REFERENCE_IMAGE_DIR in the project build settings.

It leads to a part of the command line reading (for a build folder of /Users/richard/Test Folder With Spaces/TTTAttributedLabel/Example):

-DDEBUG -DCOCOAPODS=1 -DFB_REFERENCE_IMAGE_DIR=\"/Users/richard/Test -DFolder -DWith -DSpaces/TTTAttributedLabel/Example/TTTAttributedLabelTests/ReferenceImages\" -DOBJC_OLD_DISPATCH_PROTOTYPES=0

which isn't going to end well. The first (of 20) errors thrown is:

In file included from <built-in>:338:
<command line>:4:32: warning: missing terminating '"' character [-Winvalid-pp-token]
#define FB_REFERENCE_IMAGE_DIR "/Users/richard/Test

From the answer here: http://stackoverflow.com/questions/6052220/xcode-srcroot-not-working-even-though-paths-seem-to-exist/6060537#6060537 I tried setting the Preprocess Macro line to:

FB_REFERENCE_IMAGE_DIR=\""$(SOURCE_ROOT)/TTTAttributedLabelTests/ReferenceImages\""

and that makes it build (for clarity - added extra un-escaped " inside the escaped one to get XCode to expand the path nicely).
