1.Unity導出工程時設置bundle id要與項目一致
2.修改bit code爲NO
3.刪除Main.storyboard,代碼設置控制器(方便切換window)
4.將Classes,Libraries,MapFileParser.sh拖入到項目(選中Copy items if needed, 選中Create groups)
將Data拖入到項目(選中Copy items if needed, 選中Create folder references)
5.添加framework(最下邊三個是HiAR UnitySDK裏邊的)
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版本號與導出工程的Unity版本號一致)
9.Unity/Classes/Prefix.pch 的代碼複製到新建的pch文件, 設置pch文件路徑
10.將Classes/main.mm全部內容複製到main.m 並把擴展名改爲.mm, 修改如下代碼
11.添加Run Script
12. 修改UnityAppController.h如下代碼
13.在AppDelegate.h .m中添加如下代碼
在集成過程中可能遇到的問題
1.Unknown type name 'UnityViewControllerBase'
UnityViewControllerBase報錯, 把它改成UIViewController
2. Unknown type name 'AppDelegate'
在新建的項目裏邊不會報錯, 但是我集成到公司項目的時候報這個錯, 於是改成如下代碼, 目前沒有出現問題, 如果有人知道原因, 請在評論區告訴我
3. Undefined symbols for architecture armv7
遇到這個錯的同學請添加AssetsLibrary.framework和Accelerate.framework
4.編譯時遇到Permission denied錯誤的是因爲當前開發賬號對項目目錄沒有權限執行MapFileParser.sh
解決辦法: 在終端執行命令 sudo chmod -R 777 所在的目錄
5. Functions that differ only in their return type cannot be overloaded
解決辦法: 把Enable Strict Checking of objc_msgSend Calls 改爲NO
6. Control reaches end of non-void function
C++混編需要設置的地方
7.刪除unity自帶的.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)
解決辦法:
找到對應的RegisterMonoModules.cpp文件,註釋掉重複的方法:
#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() {}
