iOS codeview

1.环境配置

oclint：http://oclint.org/

xcpretty：https://github.com/supermarin/xcpretty

使用Mac安装xcpretty过程可能会出现自带ruby版本错误，需要升级ruby

$ curl -L get.rvm.io | bash -s stable
$ source ~/.rvm/scripts/rvm
$ rvm list known
$ rvm install 2.2.0
rvm use 2.2.0 --default 

2.代码扫描

xcodebuild clean build -sdk iphonesimulator -arch "x86_64" ONLY_ACTIVE_ARCH=NO VALID_ARCHS="i386 x86_64" | xcpretty -r json-compilation-database
cp build/reports/compilation_db.json compile_commands.json
oclint-json-compilation-database -e Pods -- -rc=LONG_LINE=200 -rc=NCSS_METHOD=100 -o=report.html

如果扫描的生成的compile_commands.json文件过大，oclint-json-compilation-database会提示出错“OSError: [Errno 7] Argument list too long”
