- have a look at the CoverStory Howto,
- download CoverStory,
- open (with XCode) the XCode Project you want to measure,
- run the script EnableGCov.scpt linked to from the howto,
- run your tests and see a linker error, โ dead end for the time being. http://groups.google.com/group/coverstory-discuss/browse_thread/thread/fbcbf5ed61d8d02b#
