【问题描述】：

我是 Unity3D 的新手。我的要求是在 iOS 原生应用程序之间拥有游戏屏幕（由 Unity3D 构建）。我已经编写了 .mm 以继承 UnityAppController.mm 的子类

#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

注意到在 UnityAppController.mm 中的 transitionToViewController 方法中 _rootViewController 被垃圾收集，这会引发错误访问。

有这方面的经验吗？

非常感谢！

【问题讨论】：

您可能希望从您拥有的错误消息中删除（这是无害的）消息，因为现在是这样。我什至在大量文本中找不到错误消息
抱歉！希望现在能有所帮助..
请将错误发布为文本，您可以分别复制和粘贴调用堆栈和代码片段。图像变得难以阅读。
尝试将[UIStoryboard storyboardWithName:@"Storyboard" bundle:nil];改为[UIStoryboard storyboardWithName:@"Main" bundle:nil];

【解决方案1】：

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;
    */
}

@end
