1.Unity导出工程时设置bundle id要与项目一致
2.修改bit code为NO
3.删除Main.storyboard,代码设置控制器(方便切换window)
4.将Classes,Libraries,MapFileParser.sh拖入到项目(选中Copy items if needed, 选中Create groups)
将Data拖入到项目(选中Copy items if needed, 选中Create folder references)
5.添加framework(最下边三个是HiAR UnitySDK里边的)
6.添加 Header Search Paths 和 Library Search Paths
7.other C Flags -> -DINIT_SCRIPTING_BACKEND=1
8.添加User-Defined (UNITY_RUNTIME_VERSION版本号与导出工程的Unity版本号一致)
9.Unity/Classes/Prefix.pch 的代码复制到新建的pch文件, 设置pch文件路径
10.将Classes/main.mm全部内容复制到main.m 并把扩展名改为.mm, 修改如下代码
11.添加Run Script
12. 修改UnityAppController.h如下代码
13.在AppDelegate.h .m中添加如下代码
在集成过程中可能遇到的问题
1.Unknown type name 'UnityViewControllerBase'
UnityViewControllerBase报错, 把它改成UIViewController
2. Unknown type name 'AppDelegate'
在新建的项目里边不会报错, 但是我集成到公司项目的时候报这个错, 于是改成如下代码, 目前没有出现问题, 如果有人知道原因, 请在评论区告诉我
3. Undefined symbols for architecture armv7
遇到这个错的同学请添加AssetsLibrary.framework和Accelerate.framework
4.编译时遇到Permission denied错误的是因为当前开发账号对项目目录没有权限执行MapFileParser.sh
解决办法: 在终端执行命令 sudo chmod -R 777 所在的目录
5. Functions that differ only in their return type cannot be overloaded
解决办法: 把Enable Strict Checking of objc_msgSend Calls 改为NO
6. Control reaches end of non-void function
C++混编需要设置的地方
7.删除unity自带的.pch和main.mm文件
8.linker command failed with exit code 1

ld: 4 duplicate symbols for architecture arm64
clang: error: linker command failed with exit code 1(use -v to see invocation)
解决办法:
找到对应的RegisterMonoModules.cpp文件,注释掉重复的方法:
#if !INIT_SCRIPTING_BACKEND
extern void RegisterAllClassesGranular();
//void RegisterAllClasses()
//{
// // Register classes for unit tests
// RegisterAllClassesGranular();
//}
//
//void RegisterAllStrippedInternalCalls() {}
//
//void InvokeRegisterStaticallyLinkedModuleClasses() {}
//void RegisterStaticallyLinkedModulesGranular() {}
#endif // INIT_SCRIPTING_BACKEND
void RegisterMonoModules() {}
9.[DYMTLInitPlatform] platform initialization successful启动报错,
