ios - 统一 3d |后处理构建 |在为 iOS 构建创建 xcode 项目时，如何从 unity 脚本将新的运行脚本添加到 PBXProject？

Question

我正在使用适用于 iOS 平台的 Unity 3d 创建一个游戏应用程序。当 Unity 3d 为 iOS 构建创建 xCode 项目时，我希望 xcode 项目具有一些预定义的构建阶段和运行脚本。那么我应该在 PostProcessBuild 中编写什么代码来实现这一点？

Answer 1

关于你的问题，你可以引用下面这个链接:

https://bitbucket.org/Unity-Technologies/xcodeapi/src/stable/

之前因为工作原因用过

我下载了它并做了一些代码转换。我在Unity中打包Xcode工程测试后，可以实现如下需求:

1.修改Build Phases，如添加Run Script。

2.添加嵌入式框架。

3.添加系统框架

4.修改build设置。

5.修改Info.plist.

6.修改UnityAppController.mm。

其他引用代码可以自行测试。

我把代码 here ，下载的XcodeAPI代码需要和Unity自带的Xcode API区分开来。我添加了一个命名空间:Users.Custom。

using System;
using UnityEngine;
#if UNITY_EDITOR && UNITY_IOS
using UnityEditor;
using UnityEditor.Callbacks;
//using UnityEditor.iOS.Xcode;
using Users.Custom; //
#endif
using System.IO;
using System.Linq;
using System.Collections.Generic;
using System.Text.RegularExpressions;
