These steps will help.
这些步骤会有所帮助。
Create a new build configuration (‘Coverage'), duplicated from the ‘Debug' configuration.
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”Compile application with Coverage mode.
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
创建一个新的构建配置（“Coverage”），从“调试”配置复制。
打开主目标的构建设置，确保选择了新配置，然后：
Enable “Generate Test Coverage Files” Enable “Instrument Program Flow” Add “-lgcov” to “Other Linker Flags”使用 Coverage 模式编译应用程序。
检查应用程序包文件夹中的 .gcno 文件。
覆盖范围-iphonesimulator/applicationname.build/Objects-normal
使用 CoverStory 打开 .gcno 文件。从http://code.google.com/p/coverstory/downloads/list下载 CoverStory

I couldn't find a good example of this, so hopefully this will help someone else.
我找不到一个很好的例子，所以希望这会帮助别人。
If you want to generate HTML from your code coverage (once you get your .gcda files generated), you can install lcovand use these commands:
如果你想从你的代码覆盖率中生成 HTML（一旦你生成了 .gcda 文件），你可以安装lcov并使用这些命令：
function generate-codecoverage-html() {
if [[ == "-h" || ! $# -eq 2 ]]; then
echo " usage: ##代码## path/to/codecoverage/dir/ path/to/htmldir/"
return
fi
timestamp=$(date)
tmpfile="/tmp/codecoverage.info-$date"
lcov --no-checksum --directory "" --capture --output-file "$tmpfile"
genhtml --output-directory "" "$tmpfile"
}
