<b>一.配置问题<b>

<b>1.将unity工程中的这几个文件夹copy到ios工程中的根目录下面</b>

文件夹截图.png

<b>2.在工程中引入，class，libraries，data，MapFileParse.sh。并且删除class-native-所有.h文件</b>

data引入与其他不一样.png

<b>3.在工程中添加需要的库</b>

除系统外的库为第三方库.png

<b>4.build setting中更改配置选项</b>

1.enable Bitcode NO

<b>二.代码部分</b>

//AppDelegate.h
#import "AppDelegate.h"

inline UnityAppController*  GetAppController()
{
    AppDelegate*delegate = (AppDelegate*)[UIApplication sharedApplication].delegate;
    return delegate.unityController;
}

//pch文件
#ifdef __OBJC__
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
#import "UnityAppController.h"
#endif

#include "Preprocessor.h"
#include "UnityTrampolineConfigure.h"
#include "UnityInterface.h"

#ifndef __OBJC__
#if USE_IL2CPP_PCH
#include "il2cpp_precompiled_header.h"
#endif
#endif

#ifndef TARGET_IPHONE_SIMULATOR
#define TARGET_IPHONE_SIMULATOR 0
#endif

#define printf_console printf

//删除unity的 main.mm  复制到ios工程的main.m并改为main.mm

//修改的地方
#import "AppDelegate.h"
UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));

//AppDelegate.h添加部分 
#import <UIKit/UIKit.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>

}

}

<b>三.常见坑<b>
1.clang: error: no such file or directory: 'CoreMotion'
位置不能改变

-weak_framework
CoreMotion
-weak-lSystem
-licucore

2.main.mm
3.UnityAppController

AppDelegate*delegate = (AppDelegate*)[UIApplication sharedApplication].delegate;
return delegate.unityController;

4.相机权限

Privacy - Camera Usage Description
Camera access required for target detection and tracking
