IPA重签名工具

我们可以通过 shell 脚本执行重签名操作,将embedded.mobileprovision、entitlements.plist、ipa、shell文件放到同一个目录下。cd 到对应文件下，输入sh xxx.sh xx.ipa运行脚本即可。

如果项目内有多个动态库和扩展库的签名文件，都会进行重新签名。相关的shell脚本代码如下:

#!/bin/sh

if ! ([ -f "$1" ]); then
echo ----- \"${1}\"IPA文件不存在
exit
fi

ipaName=${1%.ipa}

if [ "$ipaName" = "$1" ]; then
echo ----- \"${1}\"error 不是ipa文件
exit
fi

## 证书名称
signName="iPhone Distribution: Hirich xxx Company Limited"

## step 1 解压ipa
echo "step 1 解压ipa"
unzip ${ipaName}.ipa

## step 2 删除旧签名文件
echo "step 2 删除旧签名文件 $app_path"
rm -rf Payload/*.app/_CodeSignature/

## step 3 拷贝证书配置和权限文件
echo "step 3 拷贝证书配置和权限文件"
cp embedded.mobileprovision Payload/*.app/embedded.mobileprovision

## step 4  重签frammework
echo "step 4 重签frammework"
framework_path=Payload/*.app/Frameworks
#判断有没有这个文件夹
if [ -e $framework_path ]
then
    for f in ${framework_path}/*
    do
        codesign -fs "${signName}" "${f}"
    done
fi

## step 5  重签 推送扩展
echo "step 5 重签 推送扩展"
extension_path=Payload/*.app/PlugIns
#判断有没有这个文件夹
if [ -e $extension_path ]
then
    for f in ${extension_path}/*
    do
        codesign -fs "${signName}" "${f}"
    done
fi

## step 6 重签名,这里要用到entitlements.plist文件，签名不对会安装失败
echo "step 6 重签名整个包"
/usr/bin/codesign -f -s "$signName" --entitlements entitlements.plist Payload/*.app/

## step 7 打包
echo --- "开始打包"
zip -r ${ipaName}_resign.ipa Payload/
rm -rf Payload/
rm -rf __MACOSX/
