本教程环境为：Unity2017.3.1f1、Xcode10.1

1.设置开发者账号

using UnityEngine;
using UnityEditor;
using UnityEditor.Callbacks;
using UnityEditor.iOS.Xcode;
using System.Collections;
using System.IO;
using System.Text.RegularExpressions;


public class XCodeProjectMod : MonoBehaviour {
    [PostProcessBuild]
    public  static  void OnPostprocessBuild (BuildTarget BuildTarget, string path) {
        if (BuildTarget == BuildTarget.iOS) {
            //这里是固定的
            string projPath = PBXProject.GetPBXProjectPath(path);
            PBXProject proj = new PBXProject();
            proj.ReadFromString(File.ReadAllText(projPath));
            string target = proj.TargetGuidByName("Unity-iPhone");

            // set code sign identity & provisioning profile
            proj.SetBuildProperty (target, "CODE_SIGN_IDENTITY", "iPhone Developer: ming xing (9V4FTD5US7)");//替换你的code sign identity
            proj.SetBuildProperty (target, "PROVISIONING_PROFILE_SPECIFIER", "com.companyname");//替换你的provisioning profile specifier
            //proj.SetBuildProperty (target, "CODE_SIGN_ENTITLEMENTS", "KeychainAccessGroups.plist");
            proj.SetBuildProperty (target, "DEVELOPMENT_TEAM", "A3A6A4A6DB");//替换你的development team
            proj.SetBuildProperty (target, "CODE_SIGN_STYLE", "Manual");

            //ulua 库不支持 bitcode必须要关闭，才能打包
            proj.SetBuildProperty(target,"ENABLE_BITCODE", "NO");

            File.WriteAllText(projPath, proj.WriteToString());
        }
    }
}

2.编写一键打包shell文件

（不明白请查看https://blog.csdn.net/qq_14974975/article/details/83825522，本教程大部分引用此网页内容）
建一个.sh文件，放到工程根目录

#!/bin/sh

#Log颜色处理-------------start
function infolog()
{
    echo -e Log: "\033[32m$1\033[0m"
}

#输出报错log
function errorlog()
{
    echo -e Error: "\033[01;31m$1\033[0m"
}

#输出报错log并停止运行
function errorlogExit()
{
    echo -e Error: "\033[01;31m$1\033[0m"
    echo -e Error: "\033[01;31m打包失败\033[0m"
    exit
}
#Log颜色处理-------------end

#游戏程序路径 需要将本文件放入unity工程目录中#
PROJECT_PATH=$(dirname "$0")

#解析打包配置文件
CONFIG_PLIST=${PROJECT_PATH}"/build/iOS/Info/exportinfo.plist"

# 版本号
CONFIG_Version=$(/usr/libexec/PlistBuddy -c 'Print :CFBundleShortVersionString' $CONFIG_PLIST)
#Xcode工程版本号
CFBundleShortVersionString=$CONFIG_Version

# 打包格式文件
CONFIG_exportOptionsPlist_Name=$(/usr/libexec/PlistBuddy -c 'Print :exportOptionsPlist' $CONFIG_PLIST)
CONFIG_exportOptionsPlist=${PROJECT_PATH}"/build/iOS/Info/"${CONFIG_exportOptionsPlist_Name}

# 是否为Il2cpp模式打包
CONFIG_isIl2cpp=$(/usr/libexec/PlistBuddy -c 'Print :isIl2cpp' $CONFIG_PLIST)

# build号
CFBundleVersion=$(/usr/libexec/PlistBuddy -c 'Print :buildVersion' $CONFIG_PLIST)

#这是游戏导出的ipa名字，记得修改这里
app_name="appname"
# 拼接游戏名称
ipa_name=${app_name}"_ios_publish_"${CFBundleShortVersionString}"."${CFBundleVersion}  

#UNITY程序的路径#
UNITY_PATH=/Applications/Unity/Unity.app/Contents/MacOS/Unity


# 传给unity的XCODE导出路径
Xcode_Untiy_ProjectPath="build/iOS/XcodeProject"

#Xcode工程目录

#将unity导出成xcode工程-----------------------------------start
    {
        #try 
        $UNITY_PATH -projectPath $PROJECT_PATH -executeMethod AutoBuild.BuildIos "Path_"${Xcode_Untiy_ProjectPath} -quit
    } || { 
        #catch
        errorlogExit "unity导出Xcode工程失败"
    }
    infolog "----------XCODE工程生成完毕,路径:"${Xcode_ProjectPath}
#将unity导出成xcode工程-----------------------------------end

#设置Xcode info.plist-----------------------------------start
#       /usr/libexec/PlistBuddy -c 'Set :CFBundleShortVersionString '${CFBundleShortVersionString} $PLIST_PATH

#设置Xcode info.plist-----------------------------------end

#开始打包ipa-----------------------------------start
    {
        #try
        #清理编译工程
        EXPORT_PATH=${PROJECT_PATH}"/build/iOS/Export/"

        infolog "----------enter Xcode Project:"${Xcode_ProjectPath}
        cd $Xcode_ProjectPath

        infolog "----------clean Xcode Project"
        xcodebuild clean -quiet

        infolog "----------archive Xcode Project:"${EXPORT_PATH}${ipa_name}
        #编译工程
        xcodebuild archive -scheme "Unity-iPhone" -configuration "Release" -archivePath  ${EXPORT_PATH}${ipa_name}"/"${app_name}"_Archive.xcarchive" -quiet || exit

        infolog "----------ipa Xcode Project"
        #打包  -archivePath Xcode导出的文件路径   -configuration 导出格式(Debug/Release)   -exportPath ipa导出路径  -exportOptionsPlist 导出模式,使用plist文件控制 在xcode手动打包时会在ipa同目录下生成对应格式的plist文件 可以直接使用改pist文件并根据不同格式备份多份
        xcodebuild -exportArchive -archivePath ${EXPORT_PATH}${ipa_name}"/"${app_name}"_Archive.xcarchive" -configuration "Release" -exportPath ${EXPORT_PATH}${ipa_name} -exportOptionsPlist ${CONFIG_exportOptionsPlist} -quiet || exit
    }||{
        #catch
        errorlogExit "xcode工程清理/打包/导出失败 请查看上层error log"
    }
#开始打包ipa-----------------------------------start

#复制字符表文件到导出ipa的文件夹------------------start
    if [ ! -d ${EXPORT_PATH}${ipa_name}"/"${app_name}"_Archive.xcarchive/dSYMs" ]; then
        errorlog "----------dSYM字符表文件未导出,检查Xcode设置!!!!!!!!!(文件夹不存在)"
    else
        cd ${EXPORT_PATH}${ipa_name}"/"${app_name}"_Archive.xcarchive/dSYMs"
        if [ ! -e ${app_name}".app.dSYM" ]; then
            #字符表文件不存在
            errorlog "----------dSYM字符表文件未导出,检查Xcode设置!!!!!!!!!(文件不存在)"
        else
            cp -R ${app_name}".app.dSYM" ${EXPORT_PATH}${ipa_name}
        fi
    fi
#复制字符表文件到导出ipa的文件夹------------------end

infolog "Ipa导出成功!!!!!!!!!"
#打开指定文件夹
open ${EXPORT_PATH}${ipa_name}

2.1Unity打包

上面"2.编写一键打包shell文件"的.sh文件有一行代码：

$UNITY_PATH -projectPath $PROJECT_PATH -executeMethod AutoBuild.BuildIos "Path_"${Xcode_Untiy_ProjectPath} -quit

提到AutoBuild.BuildIos是Unity打包的代码，需要在Unity里面编写：

public class AutoBuild
    /// <summary>
    /// ios自动打包测试
    /// </summary>
    public static void BuildIos()
    {
        // 工程导出路径
        string nXcodeOutputPath = string.Empty;
        // 解析shell传入的参数
        foreach (string commandLineArg in System.Environment.GetCommandLineArgs())
        {
            if (commandLineArg.Contains("Path_"))
            {
                nXcodeOutputPath = commandLineArg.Split('_')[1];
            }
        }
        // 设置需要打包的场景
        string launchScene = "Assets/Scenes/GameStart.unity";
        
        var buildPlayerOptions = new BuildPlayerOptions();
        buildPlayerOptions.locationPathName = nXcodeOutputPath;
        buildPlayerOptions.options = BuildOptions.None;
        buildPlayerOptions.options |= BuildOptions.AcceptExternalModificationsToPlayer;
        buildPlayerOptions.scenes = new[] { launchScene };
        buildPlayerOptions.target = BuildTarget.iOS;
        // 调用开始打包   
        BuildPipeline.BuildPlayer(buildPlayerOptions);
    }
}

2.2打包配置

上面"2.编写一键打包shell文件"的.sh文件有一行代码：

CONFIG_PLIST=${PROJECT_PATH}"/build/iOS/Info/exportinfo.plist"

提到exportinfo.plis是打包配置文件，只是为了一键打包shell和配置分开2个文件，修改配置的时候，不影响一键打包shell
配置文件exportinfo.plist如下：

<?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>exportOptionsPlist</key>
    <string>dev.plist</string>
    <key>buildVersion</key>
    <string>24</string>
    <key>CFBundleShortVersionString</key>
    <string>1.0.10</string>
    <key>isIl2cpp</key>
    <true/>
</dict>
</plist>

本教程exportinfo.plist路径为Unity工程根目录/build/iOS/Info

2.2.1archive导出ipa配置文件

上面"2.2打包配置"的.plist文件有一行代码：

<string>dev.plist</string>

提到dev.plist是archive导出ipa需要用的配置文件。自己Xcode手动打一次ipa，在ipa同目录下会看ExportOptions.plist，ExportOptions.plist就是这里提到的dev.plist。本教程dev.plist路径为Unity工程根目录/build/iOS/Info

2、2.2、2.2.1提到的3个文件路径目录如下

.sh.plist目录结构.png

3.导出ipa

将"2.编写一键打包shell文件"的.sh文件拖入终端，回车等待即可！
如果提示.sh文件没有权限，cd到脚本目录，chmod +x 脚本名.sh即可
