unity2019版本融合iOS基本思路：Xcode ⼯程创建⼯作空间，⼀个⼯作空间包含 iOS原⽣⼯程，⼀个为3D⼯程。通过ork 进⾏桥接通信。 unity⼯程注册代理，原⽣实现交互⽅法、unity 调取iOS 代理模式交互数据。iOS调取unity 通过UnityFramework 提供的发送消息⽅法。1.⽣成iOS⼯程⾸先在Unity编辑器打开UnityProject项⽬，选择Menu -> Window -> Package Manager，因为2.0.8版本不兼容使⽤Unity作为库，所以要移除Ads资源包，或更新Ads资源包到v 3.*版本。选择Menu -> Edit -> Player Settings -> Player -> iOS设置标签页 -> Identification Section，设置有效的Bundle Identification和SigningTeam ID，以避免后续步骤出现Xcode签名问题。打开Menu -> File -> Builds Settings，在此选择并切换平台为iOS。将UnityProject项⽬构建到iosBuild⽂件夹。2.创建Xcode⼯作空间设置Xcode⼯作空间　　Xcode⼯作空间允许同时处理多个项⽬，并结合它们的结果。　　我们在Xcode打开roj。选择File -> New -> Workspace，创建⼯作空间，把它保存在UaaLExample/space。关闭roj项⽬，此后的步骤会在刚创建的⼯作空间项⽬完成。选择File -> Add Files to “both”，把roj和第2步⽣成的roj添加到相同等级的⼯作空间。3.将iOS⼯程 加⼊⼯作空间将unity导出⼯程加⼊⼯作空间如果使⽤pod 将pods ⼯程加⼊⼯作空间file -> addFile to ""3个⼯作空间平级4. 添加5.设置Data⽂件夹为 ork 部分6.公开桥接⽂件⼯程配置完毕。以下是代码配置1. 修改为 MM将 main.m 与AppDelegate 写⼊同⼀个⽂件 #include #include #include #include UnityFramework* UnityFrameworkLoad() { NSString* bundlePath = nil; bundlePath = [[NSBundle mainBundle] bundlePath]; bundlePath = [bundlePath stringByAppendingString: @"/Frameworks/ork"]; NSBundle* bundle = [NSBundle bundleWithPath: bundlePath]; if ([bundle isLoaded] == false) [bundle load]; UnityFramework* ufw = [palClass 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].ewController; [vc presentViewController:alert animated:YES completion:nil]; } int gArgc = 0; char** gArgv = nullptr; NSDictionary* appLaunchOpts; @interface AppDelegate : UIResponder @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 - 打开3D - (void)showUnityView { if(![self unityIsInitialized]) { showAlert(@"Unity is not initialized", @"Initialize Unity first"); } else { [[self ufw] showUnityWindow]; } } #pragma mark - 打开原⽣ #pragma mark - 打开原⽣ - (void)showNativeView { [ makeKeyAndVisible]; } #pragma mark - 发消息 - (void)sendMsgToUnity:(NSString *)strClass method:(NSString *)strMethod value:(NSString *)strValue { // [[self ufw] sendMessageToGOWithName: "Cube" functionName: "ChangeColor" message: "yellow"]; [[self ufw] sendMessageToGOWithName:8String functionName:8String message:8String]; }- (void)showHostMainWindow{ [self showHostMainWindow:@""];}- (void)showHostMainWindow:(NSString*)color{// if([color isEqualToString:@"blue"]) oundColor = lor;// else if([color isEqualToString:@"red"]) oundColor = or;// else if([color isEqualToString:@"yellow"]) oundColor = Color;// [UIApplication sharedApplication].ewController = ;// [ makeKeyAndVisible]; [self showNativeView];}- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch.
