原理解析

[macOS翻译]Cocoa逆向工程指南

• SIMBLAgent.app
  • 配置SIMBLAgent.app为Launch Agent，登录启动
  • 启动监听NSWorkspaceDidLaunchApplicationNotification
  • 解析userInfo，获取APP的进程pid
  • 通过Scripting Bridge向APP进程，发送SIMeload的AppleEvent
• SIMBL.osax
  • 拦截SIMeload的AppleEvent
  • 加载Plugin

Scripting Addition工程解析

• SIMBL的xcodeproj

  • productType = "com.apple.product-type.bundle"
  • WRAPPER_EXTENSION = osax
  • PBXShellScriptBuildPhase：sdp -fa -o $(PRODUCT_NAME).r $(PRODUCT_NAME).sdef
  • PBXRezBuildPhase：$(PRODUCT_NAME).sdef

• mySIMBL中包含编译好的SIMBL.osax

Resource fork简介

Wiki：en.wikipedia.org/wiki/Resour…

In macOS, forks are named file/..namedfork/forkname, e.g., the resource fork of the file IMG_0593.jpg is IMG_0593.jpg/..namedfork/rsrc. The ls command supports a -l@ option which lists a file's forks.

add_custom_command(TARGET ${myTargetApp} PRE_BUILD
    DEPENDS ${MY_SOURCE_DIR}/MyResource.r
    COMMAND ${rezCompiler}
    
    # several .r are located across the build
    -I ${MY_SOURCE_DIR}/resources/
    
    -arch x86_64
    
    # use the datafork
    -useDF
    
    # needs to specify for Carbon.r and CoreServices.r?
    #-F Carbon
    #-F CoreServices
    
    # where to find framework files
    -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/
    
    -o "${MY_SOURCE_DIR}/${myTargetApp}.rsrc"
    ${MY_SOURCE_DIR}/MyResource.r
)

While both versions of Xcode support .r files in the Copy Bundle Resources phase, invoking Rez to compile your inputs, Xcode 14 incorrectly outputs a .rsrc file whose name matches the input .r file (MyResources.r → MyResources.rsrc)

Makefile仿写

参考Xcode工程模板Cocoa Bundle的编译和资源打包

• 新建Cocoa Bundle项目
• 添加无main函数的objective-c源文件
• 用sdp和sdef生成的.r资源文件
• 添加该.r文件到Copy Bundle Resources阶段（developer.apple.com/forums/thre…
• 编译并查看编译步骤

可以仿写Makefile：github.com/Sunbreak/Qu…

installAddition: buildAddition
	mkdir -p ${ADDITION_BUNDLE}/Contents/Resources
	cp ${ADDITION_SRC}/addition.plist ${ADDITION_BUNDLE}/Contents/Info.plist
	cp ${ADDITION_SRC}/addition.sdef ${ADDITION_BUNDLE}/Contents/Resources/${ADDITION_NAME}.sdef
	sdp -fa -o ${BUILD_DIR}/addition.r ${ADDITION_SRC}/addition.sdef
	Rez -o ${ADDITION_BUNDLE}/Contents/Resources/${ADDITION_NAME}.rsrc -useDF \
		-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk \
		${BUILD_DIR}/addition.r
