Xcode Project Inspection¶

The UGLY approach¶

In this approach, what we do here is simply assembling all parameters we need to invoke OCLint for a Xcode project. For a Xcode project, usually we need the target architecture, system root (target SDK), include search paths, and framework search paths, of course, plus the files we are going to inspect.

It looks like this when we get all of these parameters together.

#! /bin/bash

LANGUAGE=objective-c
ARCH=armv7
SYSROOT=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk
CLANG_INCLUDE=/usr/lib/clang/3.0/include
PCH_PATH=target-Prefix.pch
FRAMEWORKS=''

INCLUDES=''
for folder in `find . -type d`
do
  INCLUDES="$INCLUDES -I $folder"
done

FILES=''
for file in `find . -name "*.m"`
do
  FILES="$FILES $file"
done

oclint -x $LANGUAGE -arch $ARCH -isysroot=$SYSROOT -I $CLANG_INCLUDE $INCLUDES -include $PCH_PATH $FILES

You can create an executable bash file based on the template above, save it in your Xcode project folder, modify to fit your needs, and just call

./oclint-xcode.sh

to kick-off the inspection.

A Better Approach¶

As all information we need to invoke OCLint is configured in Xcode project’s configuration file projectname.xcodeproj/project.pbxproj, the better approach is obviously get all these parameters from this configuration file.

Currently, we are working on this approach as a Ruby project. We use pbxproject gem to parse the information we need, and gli gem for command line options.
