1.先准备好原生工程【KW_OC】和导出的unity工程【UnityProject】

2.打开UnityProject，检查Data文件是否勾选UnityFramework

3.选择真机设备，Command+B 进行编译，编译成功后会看到 UnityFramework文件变色了

4.点击Show in Finder ，打开文件目录

5.将Unity项目嵌入原生项目

• 打开原生工程，左下角 + 按钮

• 选中xcodeproj文件，右下角add

• 现在原生工程文件目录就变成这样了

• 编译UnityFramework 【Command + B】

• 配置Framework

• • Frameworks，Librarys，and... 展开后点击+ ， AddFile
• • 把刚才的framework文件拖进来，点击open

6.嵌入完成 进入代码部分

• appdelegate.h 文件

#include <UnityFramework/UnityFramework.h>
#include <UnityFramework/NativeCallProxy.h>

@property UnityFramework* ufw;

• appdelegate.m 文件

#import "AppDelegate.h"

UnityFramework* UnityFrameworkLoad() {
    NSString* bundlePath = nil;
    bundlePath = [[NSBundle mainBundle] bundlePath];
    bundlePath = [bundlePath stringByAppendingString: @"/Frameworks/UnityFramework.framework"];
    NSBundle* bundle = [NSBundle bundleWithPath: bundlePath];

    if ([bundle isLoaded] == false) [bundle load];

    UnityFramework* ufw = [bundle.principalClass getInstance];
    if (![ufw appController]) {
        [ufw setExecuteHeader: &_mh_execute_header];
    }
    return ufw;
}
