Xcode中如何集成Unity

項目中須要集成unity，摸索了大半周，碰到了不少坑，終於搞定。

個人方法是，經過unity導出一個空的iOS項目，而後再新建一個Xcode項目，針對配置頁面一一對應。直到配置徹底同樣，而後倒入相關資源文件。從untiy導出的iOS項目我命名爲UnityProject，原生應用我命名爲Native。

1、拷貝文件

將UnityProject項目下  Classes Data Libraries MapFileParser MapFileParser.sh  拷貝到Native主項目 根目錄下

2、添加framework

3、配置

一、添加run script

二、添加Search Paths

Header Search Paths 添加
"$(SRCROOT)/Classes"
"$(SRCROOT)"
$(SRCROOT)/Classes/Native
$(SRCROOT)/Libraries/bdwgc/include
$(SRCROOT)/Libraries/libil2cpp/include

Library Search Paths 添加
$(inherited)
"$(SRCROOT)"
"$(SRCROOT)/Libraries"

三、添加預處理文件

Classes/Prefix.pch

四、添加 -DINIT_SCRIPTING_BACKEND=1

4、修改main.m

• 複製Classes/main.mm內容到main.m  修改main.m的擴展名爲.mm
• 刪除Unity生成main.mm
• return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));

5、修改 unityAppController

inline UnityAppController* GetAppController()
{
return (UnityAppController*)[[UIApplication sharedApplication] valueForKeyPath:@"delegate.unityAppController"];

}

 

6、修改 appdelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    BOOL returnBool;
    if (_unityAppController == nil) {
        
        _unityAppController = [[UnityAppController alloc] init];
    }
    returnBool = [_unityAppController application:application didFinishLaunchingWithOptions:launchOptions];
//    self.window = _unityAppController.window;
    
    HelloViewController *vc = [[HelloViewController alloc] init];
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:vc];
    self.window.rootViewController = nav;
    [self.window makeKeyAndVisible];
    
    return YES;
    
}

- (void)applicationWillResignActive:(UIApplication *)application {
    [_unityAppController applicationWillResignActive:application];
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
    // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}

- (void)applicationDidEnterBackground:(UIApplication *)application {
    [_unityAppController applicationDidEnterBackground:application];

    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}

- (void)applicationWillEnterForeground:(UIApplication *)application {
    [_unityAppController applicationWillEnterForeground:application];

    // Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
    [_unityAppController applicationDidBecomeActive:application];

    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}

- (void)applicationWillTerminate:(UIApplication *)application {
    [_unityAppController applicationWillTerminate:application];
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}

錯誤總結

一、Expected identifier or '('

修改UnityViewControllerBaseiOS.h

#ifdef __cplusplus
extern "C" {
#endif
    void AddViewControllerRotationHandling(Class class_, IMP willRotateToInterfaceOrientation, IMP didRotateFromInterfaceOrientation, IMP viewWillTransitionToSize);
#ifdef __cplusplus
}
#endif

#ifdef __cplusplus
extern "C" {
#endif
    void AddViewControllerDefaultRotationHandling(Class class_);
#ifdef __cplusplus
}
#endif
