我有一个从 Unity 5 导出的 iOS 应用程序，我还使用 vuforia 将 ar 添加到该 Unity 应用程序。现在我想将 Unity 应用程序集成到我现有的 iOS 应用程序中。

我关注了http://www.the-nerd.be/2015/11/13/integrate-unity-5-in-a-native-ios-app-with-xcode-7/#comment-446教程，这对于在没有 Vuforia 的情况下集成 Unity 非常有用。

那么我该怎么做，而且最好使用 swift 来做到这一点

最佳答案

我为 iOS 8.4 及更高版本 集成了 Unity 5.3.8p8 和 Vuforia 6.0.117。 这些教程是为 Objective-C 制作的，但您可以毫无问题地为 Swift 制作，只需创建一个 PREFIX HEADER 并在那里导入所有 .h 文件，并在下面的示例中替换正确的代码。

为 XCode 导出 Unity 项目后，打开它并创建一个组文件夹。 在您创建的那个文件夹中，创建一个具有您想要的名称的 .mm 文件(我的是 mainAppController.mm )，有:

// mainAppController.mm
//
// Import this default headers to make Unity and Vuforia works
#import <UIKit/UIKit.h>
#import "UnityAppController.h"
#import "UI/UnityView.h"
#import "UI/UnityViewControllerBase.h"
#import "VuforiaRenderDelegate.h"

// This is your MAIN VIEWCONTROLLER, that controller you want to open first when build/open your app.
#import "MainViewController.h"



// Unity native rendering callback plugin mechanism is only supported
// from version 4.5 onwards
#if UNITY_VERSION>434
// Exported methods for native rendering callback
extern "C" void UnitySetGraphicsDevice(void* device, int deviceType, int eventType);
extern "C" void UnityRenderEvent(int marker);

// This is for Vuforia Render Delegate, i copy it from VuforiaNativeRenderController.mm and add here to make it work

extern "C" void VuforiaSetGraphicsDevice(void* device, int deviceType, int eventType);
extern "C" void VuforiaRenderEvent(int marker);

#endif

@interface mainAppController : UnityAppController<UIApplicationDelegate>

// My historyboard works with NavigationController.
// If your app doenst use navigation, just open the historiboard with your main ViewController.

@property (nonatomic, strong) UINavigationController *navigationController;

- (void)willStartWithViewController:(UIViewController*)controller;
- (void)shouldAttachRenderDelegate;

@end



@implementation mainAppController


- (void)shouldAttachRenderDelegate
{

    self.renderDelegate = [[VuforiaRenderDelegate alloc] init];
    // Unity native rendering callback plugin mechanism is only supported
    // from version 4.5 onwards
#if UNITY_VERSION>434
    //
    // I comment this line bellow because Vuforia hendle it, and you see what will work with Vuforia.
    //
    //UnityRegisterRenderingPlugin(&UnitySetGraphicsDevice, &UnityRenderEvent);
    UnityRegisterRenderingPlugin(&VuforiaSetGraphicsDevice, &VuforiaRenderEvent);
#endif

}


- (void)willStartWithViewController:(UIViewController*)controller {

    //
    // Open your historyboard with your main view.
   // In my case i use navigation controller.

    UIStoryboard *storyBoard;
    storyBoard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];

    _rootController         = [[UnityDefaultViewController alloc] init];
    _rootView               = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    _rootController.view    = _rootView;

    MainViewController *mainVC       = [storyBoard instantiateViewControllerWithIdentifier:@"idMainViewController"];

    self.navigationController = [[UINavigationController alloc] initWithRootViewController:mainVC];

    [_rootView addSubview:self.navigationController.view];
}

@end


//
// You have to put this line below and comment out the equal line below in file VuforiaNativeRenderController.mm
//
IMPL_APP_CONTROLLER_SUBCLASS(mainAppController)

您注意到我正在使用 Storyboard。 所以我的 MainViewController 是导航 Controller 的 ViewController 根。正确的! 在我的 MainViewController 中，我这样做:

//  MainViewController.h
//

#import <UIKit/UIKit.h>
#import "UnityAppController.h"
#import "UI/UnityView.h"
#import "UI/UnityViewControllerBase.h"

@interface MainViewController : UIViewController
{
    UnityDefaultViewController *unityViewController;
    UnityAppController *unityController;
}

-(IBAction) touchToLoad:(id)sender;

@end

//  MainViewController.m
//
// This is just a EXAMPLE FILE, that i use in my project.
#import "MainViewController.h"
#import "ARViewController.h"

@interface MainViewController ()

@end

@implementation MainViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    // My project use navigation controller just for transition animation right to left, thats why i hide it here on first view.

    [self.navigationController setNavigationBarHidden:YES];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}


#pragma mark - Navigation

// In a storyboard-based application, you will often want to do a little preparation before navigation
//- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
//{
//    if ([segue.identifier isEqualToString:@"idHomeViewController"])
//    {
////        MyViewController *controller = (MyViewController *)segue.destinationViewController;
////        controller.myProperty1 = ...;
////        controller.myProperty2 = ...;
//    }
//    
//    
//}


-(void)touchToLoad:(id)sender
{
    //
    // Open historyboard with Unity and Vuforia, see details on ARViewController.h/m

    UIStoryboard *storyBoard;
    storyBoard                      = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    ARViewController *mainVC        = [storyBoard instantiateViewControllerWithIdentifier:@"idARViewController"];
    [self.navigationController pushViewController:mainVC animated:YES];
}

@end

为了更好地了解，我在 Storyboard 中放置了一个按钮以转到 Unity View 。这样我就可以处理来自 xcode 的 native UI。 然后我有显示 Unity 和 Vuforia 工作的 ARViewController。

//  ARViewController.h
//
//

#import <UIKit/UIKit.h>
#import "UnityAppController.h"
#import "UI/UnityView.h"
#import "UI/UnityViewControllerBase.h"


@interface ARViewController : UIViewController
{
    IBOutlet UIView     *viewToUnity;
    UnityDefaultViewController *unityViewController;
    UnityAppController *unityController;
}

-(IBAction) goBack:(id)sender;

@end

//  ARViewController.m
//
//

#import "ARViewController.h"
#import <QuartzCore/QuartzCore.h>

@interface ARViewController ()

@end

@implementation ARViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Just setting Unity delegates and view to add it as subview for my main view.
    // This allow me to add a UIButton above the UnityView to popViewController or anything i want to make native in iOS.

    unityViewController         = [[UnityDefaultViewController alloc] init];
    unityController             = (UnityAppController*)[[UIApplication sharedApplication] delegate];
    unityViewController.view    = (UIView*)unityController.unityView;

    [viewToUnity addSubview:unityViewController.view];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

/*
#pragma mark - Navigation

// In a storyboard-based application, you will often want to do a little preparation before navigation
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    // Get the new view controller using [segue destinationViewController].
    // Pass the selected object to the new view controller.
}
*/

#pragma MARK -- Methods
-(void)goBack:(id)sender
{
    [self.navigationController popViewControllerAnimated:YES];
}

@end

我做了一个 repo 来下载一个正在运行的项目。
https://bitbucket.org/jack_loverde/unity-5-vuforia-6-and-ios-native-integration如果您想测试此版本是否正常工作。

希望对你有帮助。

谢谢
