unity2019版本融合iOS

基本思路：

Xcode 工程创建工作空间，一个工作空间包含 iOS原生工程，一个为3D工程。通过UnityFramework.framework 进行桥接通信。 unity工程注册代理，原生实现交互方法、
unity 调取iOS 代理模式交互数据。
iOS调取unity 通过UnityFramework 提供的发送消息方法。

正文：
Unity 2019.3.a2及更高版本，以及Xcode 9.4及更高版本。
下载Unity 2019.3.a2： https://unity3d.com/alpha/2019.3

1.生成iOS工程
首先在Unity编辑器打开UnityProject项目，选择Menu -> Window -> Package Manager，因为2.0.8版本不兼容使用Unity作为库，所以要移除Ads资源包，或更新Ads资源包到v 3.*版本。

选择Menu -> Edit -> Player Settings -> Player -> iOS设置标签页 -> Identification Section，设置有效的Bundle Identification和Signing Team ID，以避免后续步骤出现Xcode签名问题。

打开Menu -> File -> Builds Settings，在此选择并切换平台为iOS。将UnityProject项目构建到iosBuild文件夹。

2.创建Xcode工作空间
设置Xcode工作空间
　　Xcode工作空间允许同时处理多个项目，并结合它们的结果。
　　我们在Xcode打开NativeiOSApp.xcodeproj。选择File -> New -> Workspace，创建工作空间，把它保存在UaaLExample/both.xcworkspace。

关闭NativeiOSApp.xcodeproj项目，此后的步骤会在刚创建的工作空间项目完成。

选择File -> Add Files to “both”，把NativeiOSApp.xcodeproj和第2步生成的Unity-iPhone.xcodeproj添加到相同等级的工作空间。

3.将iOS工程 加入工作空间
将unity导出工程加入工作空间
如果使用pod 将pods 工程加入工作空间
file -> addFile to ""

3个工作空间平级

4. 添加UnityFramework.framework

5.设置Data文件夹为 UnityFramework.framework 部分

6.公开桥接文件

工程配置完毕。以下是代码配置

1. AppDelegate.mm 修改为 MM
   将 main.m 与AppDelegate 写入同一个文件

采坑经验：
1.Data文件夹一定要 包含到 UnityFramework.framework 不然报错
2.NativeCallProxy.h 包含到 UnityFramework.framework 并且公开

3. 报错 # [MapFileParser.sh: Permission denied]
   此报错因文件权限问题导致
   执行指令
   chmod +x /Users/......./MapFileParser.sh （MapFileParser.sh所在的目录）
   4.unity启动成功 直接跳入3D页面
   找到 unity工程中的几处跳转 全部注释
   关键字 [window makeKeyAndVisible];

   5.僵尸断点会导致untiy工程内存持续增加。不要勾选
