iOS APP 重签名

参考文章：https://objccn.io/issue-17-2/

• 查看本地证书
  security find-identity -v -p codesigning

• 查看IPA签名信息(注意是.app 而不是.ipa ,查看的是解压后的包。通过预览空格也可以查看基本信息)
  codesign -vv -d ipaName.app

  
  codesign -vv -d.png
  • 你需要查看的第一件事是以 Authority 开头的那三行。这三行告诉你到底是哪一个证书为这个 app 设置了签名。在这里当然是我的证书，iPhone Developer: chunhua zhou (PM246VG2Z9)。我的这个证书则是被证书 Apple Worldwide Developer Relations Certification Authority 设置了签名的，依此类推这个证书则是被证书 Apple Root CA 设置了签名。
• 查看.mobileprovision 的内容
  security cms -D -i embedded.mobileprovision

签名流程

• 解压IPA
  unzip ipaName.ipa
• 删除 app 原有签名
  rm -rf Payload/ipaName.app/_CodeSignature/
• 替换证书配置文件(mobileprovision文件从开发者网站下载Provisioning Profiles并改名为embedded.mobileprovision)

$ cp ~/Desktop/embedded.mobileprovision Payload/ipaName.app/embedded.mobileprovision

• 如果存在Frameworks子目录，则对.app文件夹下的所有Frameworks进行签名，在Frameworks文件夹下的.dylib或.framework
  codesigning
• 重签名

$ security cms -D -i "xxx.mobileprovision"
//使用该命令进行查看xxx.mobileprovision文件的相关内容，可以找到以Entitlements为key的字典值。
//新建一个.plist文件，将上述值复制到plist文件中。如下示例：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>keychain-access-groups</key>
    <array>
        <string>AD9JDJKJKA.*</string>
    </array>
    <key>get-task-allow</key>
    <false/>
    <key>application-identifier</key>
    <string>AD9JDJKJKA.com.resign.test</string>
    <key>com.apple.developer.team-identifier</key>
    <string>AD9JDJKJKA</string>
    <key>aps-environment</key>
    <string>production</string>
    <key>beta-reports-active</key>
    <true/>
</dict>
</plist>

    codesign -f -s "iPhone Distribution: ******* Co., Ltd." --entitlements entitlements.plist  Payload/ipaName.app

entitlements.plist

• -f ：codesign 会用你选择的签名替换掉已经存在的那一个，如果要签名没有签名的APP可以不用 -f 。
• 还需要进入 Payload/ipaName.app 中修改 info.plist 。
• 重新打包
  zip -qr ipaName-resigned.ipa Payload/

通过将命令合并写到一个autoswimfi.sh文件中（如果无法执行，打开终端，输入：chmod 777 autoswimfi.sh 给该文件赋予权限），可以一步到位执行命令。
