These steps will help.

  1. Create a new build configuration (‘Coverage’), duplicated from the ‘Debug’ configuration.

  2. Open up build settings for the main target, make sure your new configuration is selected, and:

    Enable “Generate Test Coverage Files”
Enable “Instrument Program Flow”
Add “-lgcov” to “Other Linker Flags”

  3. Compile application with Coverage mode.

  4. Check .gcno files from your application bundle folder.

    Coverage-iphonesimulator/applicationname.build/Objects-normal

    open .gcno files with CoverStory. Download CoverStory from
    http://code.google.com/p/coverstory/downloads/list

I couldn't find a good example of this, so hopefully this will help someone else.

If you want to generate HTML from your code coverage (once you get your .gcda files generated), you can install lcov and use these commands:

function generate-codecoverage-html() {
    if [[ $1 == "-h" || ! $# -eq 2 ]]; then
        echo "    usage: $0 path/to/codecoverage/dir/ path/to/htmldir/"
        return
    fi

    timestamp=$(date)
    tmpfile="/tmp/codecoverage.info-$date"
    lcov --no-checksum --directory "$1" --capture --output-file "$tmpfile"
    genhtml --output-directory  "$2" "$tmpfile"
}
