Question

我是Unity3D的新手。我的要求是在iOS本机应用程序之间安装游戏屏幕（由Unity3D构建）。我在oder中写了.mm来继承UnityAppController.mm

#import <UIKit/UIKit.h>
#import "UnityAppController.h"

@interface TNAppController : UnityAppController

- (void)createViewHierarchyImpl;

@end

@implementation TNAppController

- (void)createViewHierarchyImpl {

    UIStoryboard *storyBoard    = [UIStoryboard storyboardWithName:@"Storyboard" bundle:nil];
    UIViewController *mainVC    = [storyBoard instantiateInitialViewController];
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window.rootViewController = mainVC;
    _rootController             = [self.window rootViewController];
    _rootView                   = _rootController.view;
}

@end

IMPL_APP_CONTROLLER_SUBCLASS(TNAppController)

但是当我尝试分配_rootView时出现以下错误。

按照http://www.the-nerd.be/2014/08/06/add-unity3d-in-a-native-ios-application/

中的教程进行操作

注意到_rootViewController在UnityAppController.mm中的transitionToViewController方法中被垃圾收集，该方法将作为错误访问而抛出。

有这方面的经验吗？

非常感谢！

这段代码，对我来说很好用：

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

#import "TopViewController.h"

@interface TNAppController : UnityAppController

@property (nonatomic, strong) UINavigationController *navController;

- (void)willStartWithViewController;

@end

@implementation TNAppController
- (void)willStartWithViewController:(UIViewController*)controller {

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

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

    //UnitySceneViewController *unityScene = [[UnitySceneViewController alloc] initWithNibName:nil bundle:nil];

    self.navController = [[UINavigationController alloc] initWithRootViewController:mainVC];
    [_rootView addSubview:self.navController.view];

    /*
    UIStoryboard *storyBoard    = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    UIViewController *mainVC    = [storyBoard instantiateInitialViewController];
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window.rootViewController = mainVC;
    _rootController             = [self.window rootViewController];
    _rootView                   = _rootController.view;
    */
}
