I'm a novice on Unity3D. My requirement is to have the the gaming screen (build by Unity3D) in between iOS native application. I have written .mm in oder to subclass 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)
But when I tried assigning the _rootView got following error.

Followed the tutorial in http://www.the-nerd.be/2014/08/06/add-unity3d-in-a-native-ios-application/
Noticed the _rootViewController is garbage collected when it comes to the transitionToViewController method in UnityAppController.mm which throws as a bad access.
Any experience on such?
Thanks a bunch!
this code, work fine for me:
#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

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

_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];
