解包ipa并提取Info.plist及Asserts.car

参考：

• Analysing Assets.car file in iOS
• acextract
• ThemeEngine
• iOS Asset Extractor
• Asset Catalog Tinkerer
• cartool
• QLCARFiles – 亲测可用

前言

在做解析ipa自动生成安装链接时，需要读取ipa的logo，特需要解析Assets.car

方式一：使用系统提供的工具

xcrun --sdk iphoneos assetutil --info Assets.car

方式二、使用三方工具，推荐 QLCARFiles – 亲测可用

1、下载源代码 https://github.com/Timac/QLCARFiles 2、运行项目 3、Product -> Show Build Folder in Finder -> /Users/xxx/Library/Developer/Xcode/DerivedData/QLCARFiles-xxxxxx/Build/Products/Debug/carDump

# 创建解压后的文件
tempAssertsDirPath
if [ -d "$tempAssertsDirPath" ]; then
    echo "删除临时解包目录 rm ${tempAssertsDirPath}"
    rm -rf "${tempAssertsDirPath}"
else
    mkdir $tempAssertsDirPath
fi

# 正式解压
carDump Assets.car /Users/xxx/xxx/output
# 查找AppIcon的图片
find /Users/xxx/xxx/output -name "AppIcon*.png"

复制找到的文件到另外的文件夹

# 找到aaa文件夹下移AppIcon开头，以.png结尾的文件，复制到bbb文件夹下
find /xxx/xxx/aaa -name "AppIcon*.png" -print0 | xargs -0 -J % cp % /xxx/xxx/bbb
# 找到ccc文件夹里类型是pdf的文件，拷贝到ddd里
find /xxx/xxx/ccc -type f -print0 | xargs -0 -J % cp % /xxx/xxx/ddd
# 查找出aaa文件夹里最大的文件
du -s ${iconDir}/* | sort -nr | head -1

参考：

• MacOS find查找文件并批量cp拷贝
• 用shell查找某目录下的最大文件
