将统一应用程序集成到现有的 iOS 应用程序 [英] Integrate unity app to existing iOS app
问题描述
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.
I have an iOS app export from Unity 5 and also I used vuforia to add ar to that Unity app. Now I want to integrate the Unity app to my existing iOS app.
我已关注 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 很有用.
I have followed http://www.the-nerd.be/2015/11/13/integrate-unity-5-in-a-native-ios-app-with-xcode-7/#comment-446 tutorial and this is good for integrating Unity without Vuforia.
那么我该如何做到这一点，而且最好使用 swift 做到这一点
So how can i do this and also its better to do this using swift
推荐答案
我为 iOS 集成了 Unity 5.3.8p8 和 Vuforia 6.0.1178.4 及更高版本.这些教程是为 Objective-C 编写的，但您可以毫无问题地为 Swift 做，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.
i made a integration with Unity 5.3.8p8 and Vuforia 6.0.117 for iOS 8.4 and up. These tutorial is made for Objective-C, but you can do for Swift with no problem, just create a PREFIX HEADER and import all .h files there and substitute for the right code in my example bellow.
为 XCode 导出 Unity 项目后，打开它并创建一个组文件夹.在您创建的文件夹中，使用您想要的名称创建一个 .mm 文件(我的是 mainAppController.mm )，有:
After you export you Unity project for XCode, open it and create a Group Folder. Inside that folder you created, create a .mm file with the name you want ( mine is mainAppController.mm ), there is:
// 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 是导航控制器的 ViewController 根.对！在我的 MainViewController 中，我这样做:
You notice that i'm using Storyboard. So my MainViewController is the ViewController root of the Navigation Controller. Right! Inside my MainViewController, i do this:
// 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
为了获得更好的知识，我在我的故事板中放置了一个按钮以转到 Unity View.这样我就可以从 xcode 处理本机 UI.然后我有显示 Unity 和 Vuforia 工作的 ARViewController.
For better knowledge, i put a button to go to Unity View inside my storyboard. So that way i can handle the native UI from xcode. Then i have the ARViewController that show Unity and Vuforia working.
// 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
我制作了一个下载项目的存储库.
https://bitbucket.org/jack_loverde/unity-5-vuforia-6-and-ios-native-integration 以防您想测试此版本是否有效.
I made a repo for download a project working.
https://bitbucket.org/jack_loverde/unity-5-vuforia-6-and-ios-native-integration in case you want to test this version working.
希望对你有帮助.
