基本思路：
Xcode 工程創(chuàng)建工作空間档痪，一個(gè)工作空間包含 iOS原生工程，一個(gè)為3D工程邢滑。通過UnityFramework.framework 進(jìn)行橋接通信腐螟。 unity工程注冊(cè)代理，原生實(shí)現(xiàn)交互方法困后、
unity 調(diào)取iOS 代理模式交互數(shù)據(jù)乐纸。
iOS調(diào)取unity 通過UnityFramework 提供的發(fā)送消息方法。

Unity 2019.3.a2及更高版本摇予，以及Xcode 9.4及更高版本汽绢。

1.生成iOS工程
首先在Unity編輯器打開UnityProject項(xiàng)目，選擇Menu -> Window -> Package Manager侧戴，因?yàn)?.0.8版本不兼容使用Unity作為庫宁昭，所以要移除Ads資源包，或更新Ads資源包到v 3.*版本酗宋。
選擇Menu -> Edit -> Player Settings -> Player -> iOS設(shè)置標(biāo)簽頁 -> Identification Section积仗，設(shè)置有效的Bundle Identification和Signing Team ID，以避免后續(xù)步驟出現(xiàn)Xcode簽名問題蜕猫。
打開Menu -> File -> Builds Settings寂曹，在此選擇并切換平臺(tái)為iOS。將UnityProject項(xiàng)目構(gòu)建到iosBuild文件夾丹锹。
2.創(chuàng)建Xcode工作空間
設(shè)置Xcode工作空間
Xcode工作空間允許同時(shí)處理多個(gè)項(xiàng)目稀颁，并結(jié)合它們的結(jié)果芬失。
我們?cè)赬code打開NativeiOSApp.xcodeproj楣黍。選擇File -> New -> Workspace，創(chuàng)建工作空間棱烂，把它保存在UaaLExample/both.xcworkspace租漂。
關(guān)閉NativeiOSApp.xcodeproj項(xiàng)目，此后的步驟會(huì)在剛創(chuàng)建的工作空間項(xiàng)目完成颊糜。
選擇File -> Add Files to “both”哩治，把NativeiOSApp.xcodeproj和第2步生成的Unity-iPhone.xcodeproj添加到相同等級(jí)的工作空間。

3.將iOS工程 加入工作空間
將unity導(dǎo)出工程加入工作空間
如果使用pod 將pods 工程加入工作空間
file -> addFile to ""

3個(gè)工作空間平級(jí)
-
添加UnityFramework.framework
image.png
5.設(shè)置Data文件夾為 UnityFramework.framework 部分

6.公開橋接文件

工程配置完畢衬鱼。以下是代碼配置
-
AppDelegate.mm 修改為 MM
將 main.m 與AppDelegate 寫入同一個(gè)文件#include <UnityFramework/UnityFramework.h> #include <UnityFramework/NativeCallProxy.h> #include <mach/mach.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; } void showAlert(NSString* title, NSString* msg) { UIAlertController* alert = [UIAlertController alertControllerWithTitle:title message:msg preferredStyle:UIAlertControllerStyleAlert]; UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"Ok" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {}]; [alert addAction:defaultAction]; // auto delegate = [[UIApplication sharedApplication] delegate]; UIViewController *vc = [UIApplication sharedApplication].delegate.window.rootViewController; [vc presentViewController:alert animated:YES completion:nil]; } int gArgc = 0; char** gArgv = nullptr; NSDictionary* appLaunchOpts; @interface AppDelegate : UIResponder<UIApplicationDelegate, UnityFrameworkListener, NativeCallsProtocol> @property (strong, nonatomic) UIWindow *window; @property UnityFramework* ufw; @property (assign, nonatomic) BOOL isStartUnity ; - (void)initUnity; - (void)ShowMainView; - (void)didFinishLaunching:(NSNotification*)notification; - (void)didBecomeActive:(NSNotification*)notification; - (void)willResignActive:(NSNotification*)notification; - (void)didEnterBackground:(NSNotification*)notification; - (void)willEnterForeground:(NSNotification*)notification; - (void)willTerminate:(NSNotification*)notification; - (void)unityDidUnloaded:(NSNotification*)notification; @end @implementation AppDelegate - (bool)unityIsInitialized { return [self ufw] && [[self ufw] appController]; } #pragma mark - 打開3D - (void)showUnityView { if(![self unityIsInitialized]) { showAlert(@"Unity is not initialized", @"Initialize Unity first"); } else { [[self ufw] showUnityWindow]; } } #pragma mark - 打開原生 - (void)showNativeView { [self.window makeKeyAndVisible]; } #pragma mark - 發(fā)消息 - (void)sendMsgToUnity:(NSString *)strClass method:(NSString *)strMethod value:(NSString *)strValue { // [[self ufw] sendMessageToGOWithName: "Cube" functionName: "ChangeColor" message: "yellow"]; [[self ufw] sendMessageToGOWithName:strClass.UTF8String functionName:strMethod.UTF8String message:strValue.UTF8String]; } - (void)showHostMainWindow { [self showHostMainWindow:@""]; } - (void)showHostMainWindow:(NSString*)color { // if([color isEqualToString:@"blue"]) self.viewController.unpauseBtn.backgroundColor = UIColor.blueColor; // else if([color isEqualToString:@"red"]) self.viewController.unpauseBtn.backgroundColor = UIColor.redColor; // else if([color isEqualToString:@"yellow"]) self.viewController.unpauseBtn.backgroundColor = UIColor.yellowColor; // [UIApplication sharedApplication].keyWindow.rootViewController = ; // [self.window makeKeyAndVisible]; [self showNativeView]; } - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch.

采坑經(jīng)驗(yàn)：
1.Data文件夾一定要 包含到 UnityFramework.framework 不然報(bào)錯(cuò)
2.NativeCallProxy.h 包含到 UnityFramework.framework 并且公開
- 報(bào)錯(cuò) # [MapFileParser.sh: Permission denied]
此報(bào)錯(cuò)因文件權(quán)限問題導(dǎo)致
執(zhí)行指令
chmod +x /Users/......./MapFileParser.sh （MapFileParser.sh所在的目錄）
4.unity啟動(dòng)成功 直接跳入3D頁面
找到 unity工程中的幾處跳轉(zhuǎn) 全部注釋
