原生iOS嵌入Unity导出的Xcode工程

• 筆記

由于最近上有类似需求 所以这两天研究了下。

一、准备工作

unity导出的xcode项目

二、开始倒腾

1、将Unity3D中的以下文件导入到工程目录下

• Data
• Classes
• MapFileParser.sh
• Libraries
• MapFileParser执行文件

注意:Data文件导入类型为Creat folde references Classes MapFileParser.sh Libraries MapFileParser执行文件 通过Creat groups导入

导入后如下图所示

2、删除引用

• 删除Libraries->libil2cpp的引用 选项为Remove Refernces
• target -> Build Phases -> DynamicLibEngineAPI 移除。如果不移除 会报错Undefined symbols for architecture arm64: …in … from:DynamicLibEngineAPI.o

3、设置classes->prefix.pch添加pch路径

4、main.m操作

将classes中main.mm 中的代码复制到项目的main.m中 并把后缀也改为mm 并将

UIApplicationMain(argc, argv, nil, [NSString stringWithUTF8String: AppControllerClassName]);

修改为

UIApplicationMain(argc, argv, nil, [NSString stringWithUTF8String: @"AppDelegate"]);

5 修改AppDelegate

AppDelegate.h

@property (strong, nonatomic) UIWindow *window;  @property (strong, nonatomic) UIWindow *unityWindow;  @property (strong, nonatomic) UnityAppController *unityController;    -(void)StartUnity; //开启unity  - (void)hideUnityWindow; //暂停

AppDelegate.m

#import "AppDelegate.h"  #import "SRViewController.h"  #import "UnityAppController.h"    @interface AppDelegate ()    @end    @implementation AppDelegate    -(UIWindow *)unityWindow{      UIWindow *window = UnityGetMainWindow();      return  window;  }    -(void)showUnityWindow{      UnityPause(false);  }    -(void)hideUnityWindow{      UnityPause(true);  }    -(void)StartUnity {      [_unityController applicationDidBecomeActive:[UIApplication sharedApplication]];      [self showUnityWindow];  }      - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {      // Override point for customization after application launch.        self.unityController = [[UnityAppController alloc] init];      [_unityController application:application didFinishLaunchingWithOptions:launchOptions];          self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];      self.window.backgroundColor = [UIColor redColor];      SRViewController *vc = [[SRViewController alloc] init];      UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:vc];        self.window.rootViewController = nav;      [self.window makeKeyAndVisible];        return YES;  }      - (void)applicationWillResignActive:(UIApplication *)application {      [_unityController applicationWillResignActive:application];  }      - (void)applicationDidEnterBackground:(UIApplication *)application {      [_unityController applicationDidEnterBackground:application];  }      - (void)applicationWillEnterForeground:(UIApplication *)application {      [_unityController applicationWillEnterForeground:application];  }    - (void)applicationDidBecomeActive:(UIApplication *)application {      [_unityController applicationDidBecomeActive:application];  }      - (void)applicationWillTerminate:(UIApplication *)application {      [_unityController applicationWillTerminate:application];  }

6 UnityAppController.h

将

inline UnityAppController* GetAppController()  {      return _UnityAppController;  }

修改为

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

7 调用

@implementation SRViewController    - (void)viewDidLoad {      [super viewDidLoad];      // Do any additional setup after loading the view.      self.navigationItem.title = @"123";      self.view.backgroundColor = [UIColor greenColor];          UIButton * btn = [[UIButton alloc] initWithFrame:CGRectMake(50, 400, 100, 50)];      [btn addTarget:self action:@selector(test:) forControlEvents:UIControlEventTouchUpInside];      [btn setTitle:@"开始" forState:UIControlStateNormal];      btn.tag = 1;      [self.view addSubview:btn];          UIButton * btn2 = [[UIButton alloc] initWithFrame:CGRectMake(50, 450, 100, 50)];      [btn2 addTarget:self action:@selector(test:) forControlEvents:UIControlEventTouchUpInside];      btn2.tag = 2;      [btn2 setTitle:@"结束" forState:UIControlStateNormal];      [self.view addSubview:btn2];    }    - (void)test:(UIButton *) btn{      AppDelegate *delegate = [UIApplication sharedApplication].delegate;      delegate.unityWindow.frame = CGRectMake(0, 0, 100, 200);        if (btn.tag == 1) {          [self.view addSubview:delegate.unityWindow];          delegate.unityWindow.hidden = NO;          [delegate StartMyUnity];      }else {          [delegate hideUnityWindow];          delegate.unityWindow.hidden = YES;      }    }

三、添加Framework以及Run Script

添加这两项的时候注意和unity的工程中保持一致

• Frameworkork 注意事项: 注意Status是Required还是Optional
• libiconv.2.dylib 通过 Add Other -> command+shift+G 搜索/usr/lib 找到libiconv.2.dylib添加

四、其他重要设置

• Enable BitCode = NO;
• Header/Library Search Paths 和unity保持一致
• Framework Search Paths 和unity保持一致
• Other linker Flags 和unity保持一致
  • all_load 如果项目中有这个 记得删除 和unity不兼容
• Supported Platforms 根据unity导出项目保持一致 最好真机
• Other C Flags、Other C++ Flags 和untiy保持一致
• C Language Dialect 保持一致
• 添加User-Defined （target->Build Settings -> Leveles右侧的加号）
  • GCC_THUMB_SUPPORT = NO
  • PROVISIONING_PROFILE
  • UNITY_RUNTIME_VERSION = unity版本号
  • UNITY_SCRIPTING_BACKEND = il2cpp
