# 04.利用Xcode进行重签名与调试

## 一、使用方式：

Xcode - Build Phases - Run Script - 添加脚本即可

## 二、脚本

```
# ${SRCROOT} 它是工程文件所在的目录
TEMP_PATH="${SRCROOT}/Temp"
#资源文件夹，我们提前在工程目录下新建一个APP文件夹，里面放ipa包
ASSETS_PATH="${SRCROOT}/APP"
#目标ipa包路径
TARGET_IPA_PATH="${ASSETS_PATH}/*.ipa"
#清空Temp文件夹
rm -rf "${SRCROOT}/Temp"
mkdir -p "${SRCROOT}/Temp"

#----------------------------------------
# 1. 解压IPA到Temp下
unzip -oqq "$TARGET_IPA_PATH" -d "$TEMP_PATH"
# 拿到解压的临时的APP的路径
TEMP_APP_PATH=$(set -- "$TEMP_PATH/Payload/"*.app;echo "$1")
# echo "路径是:$TEMP_APP_PATH"


#----------------------------------------
# 2. 将解压出来的.app拷贝进入工程下
# BUILT_PRODUCTS_DIR 工程生成的APP包的路径
# TARGET_NAME target名称
TARGET_APP_PATH="$BUILT_PRODUCTS_DIR/$TARGET_NAME.app"
echo "app路径:$TARGET_APP_PATH"

rm -rf "$TARGET_APP_PATH"
mkdir -p "$TARGET_APP_PATH"
cp -rf "$TEMP_APP_PATH/" "$TARGET_APP_PATH"



#----------------------------------------
# 3. 删除extension和WatchAPP.个人证书没法签名Extention
rm -rf "$TARGET_APP_PATH/PlugIns"
rm -rf "$TARGET_APP_PATH/Watch"



#----------------------------------------
# 4. 更新info.plist文件 CFBundleIdentifier
#  设置:"Set : KEY Value" "目标文件路径"
/usr/libexec/PlistBuddy -c "Set :CFBundleIdentifier $PRODUCT_BUNDLE_IDENTIFIER" "$TARGET_APP_PATH/Info.plist"


#----------------------------------------
# 5. 给MachO文件上执行权限
# 拿到MachO文件的路径
APP_BINARY=`plutil -convert xml1 -o - $TARGET_APP_PATH/Info.plist|grep -A1 Exec|tail -n1|cut -f2 -d\>|cut -f1 -d\<`
#上可执行权限
chmod +x "$TARGET_APP_PATH/$APP_BINARY"



#----------------------------------------
# 6. 重签名第三方 FrameWorks
TARGET_APP_FRAMEWORKS_PATH="$TARGET_APP_PATH/Frameworks"
if [ -d "$TARGET_APP_FRAMEWORKS_PATH" ];
then
for FRAMEWORK in "$TARGET_APP_FRAMEWORKS_PATH/"*
do

#签名
/usr/bin/codesign --force --sign "$EXPANDED_CODE_SIGN_IDENTITY" "$FRAMEWORK"
done
fi
```

## 三、如何安装重签名的包进行调试

### 3.1 安装

使用Xcode成功运行后会直接安装到手机上，也可以在`Products`中选择`.app`文件拷贝出来保存一下，通过下面的方式进行安装 ![安装](/files/-MZrCxq3J5yu6UgZqje2)

### 3.2 调试

![调试1](/files/-MZrCxq4cZq-oZNdcTdL) 成功！愉快的学习吧\~ ![调试2](/files/-MZrCxq5lBMH4NENgFjS)

## 四：生成重签名后的IPA

* 在项目的`Products`下找到`.app`文件，拷贝出来。
* 创建`Payload`文件夹，将上面获得的`.app`文件放入其中。
* 压缩`Payload`文件夹，修改后缀为`.ipa`即可。
