經(jīng)過(guò)各種google總共發(fā)現(xiàn)了兩個(gè)方案：
1，直接嵌入工程：嘗試各種報(bào)文件找不到。。。放棄
2，編譯產(chǎn)物接入：成功
產(chǎn)物有兩個(gè)：1UnityFramework.framework。2，Data資源。文件拖入即可
代碼步驟：
1，使用單例保存main函數(shù)參數(shù)

[ConfigObj shareInstance].gArgc = argc;
[ConfigObj shareInstance].gArgv = argv;

2，AppDelegate 添加協(xié)議UnityFrameworkListener，和相應(yīng)的property

#import <UIKit/UIKit.h>
#include <UnityFramework/UnityFramework.h>
#import "ConfigObj.h"

@interface AppDelegate : UIResponder <UIApplicationDelegate,UnityFrameworkListener>

@property (strong, nonatomic) UIWindow *window;

@property (nonatomic, strong) UnityFramework *ufw;

@end

3,加載framework，添加監(jiān)聽(tīng)等操作

#import "AppDelegate.h"
#import "UnityFramework.framework/Headers/UnityAppController.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])
    {
        // unity is not initialized
        [ufw setExecuteHeader: &_mh_execute_header];
    }
    return ufw;
}

@interface AppDelegate ()


@end

@implementation AppDelegate

- (bool)unityIsInitialized {
    return [self ufw] && [[self ufw] appController];
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    //
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
            [self initUnityWithOptions:launchOptions];
        });

    return YES;
}

- (void)initUnityWithOptions:(NSDictionary *)launchOptions
{

    
    [self setUfw: UnityFrameworkLoad()];
    // Set UnityFramework target for Unity-iPhone/Data folder to make Data part of a UnityFramework.framework and uncomment call to setDataBundleId
    // ODR is not supported in this case, ( if you need embedded and ODR you need to copy data )
    [[self ufw] setDataBundleId: "com.UnityIOS.I12"];
    [[self ufw] registerFrameworkListener: self];
//    [NSClassFromString(@"FrameworkLibAPI") registerAPIforNativeCalls:self];
    
    [[self ufw] runEmbeddedWithArgc: [ConfigObj shareInstance].gArgc argv: [ConfigObj shareInstance].gArgv appLaunchOpts: launchOptions];
    
    UIView *view = [[[self ufw] appController] rootView];
    [ConfigObj shareInstance].unityView = view;
}

- (void)applicationWillResignActive:(UIApplication *)application { [[[self ufw] appController] applicationWillResignActive: application]; }
- (void)applicationDidEnterBackground:(UIApplication *)application { [[[self ufw] appController] applicationDidEnterBackground: application]; }
- (void)applicationWillEnterForeground:(UIApplication *)application { [[[self ufw] appController] applicationWillEnterForeground: application]; }
- (void)applicationDidBecomeActive:(UIApplication *)application { [[[self ufw] appController] applicationDidBecomeActive: application]; }
- (void)applicationWillTerminate:(UIApplication *)application { [[[self ufw] appController] applicationWillTerminate: application]; }

@end

問(wèn)題記錄：
bundleId必須和framework的bundle名字一樣否則報(bào)錯(cuò)
[[self ufw] setDataBundleId: "com.unity3d.framework"];
工程的inplist文件配置copy一下，可能有重要信息
