使用storyboard自定义Unity3D Xcode项目

Question

我是Unity3D的新手。我的需求是将游戏界面（由Unity3D构建）嵌入到iOS原生应用程序中间。 为此，我编写了.mm文件以继承UnityAppController.mm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

但是当我尝试分配_rootView时，出现了以下错误。

遵循教程：http://www.the-nerd.be/2014/08/06/add-unity3d-in-a-native-ios-application/ 注意到在UnityAppController.mm的transitionToViewController方法中，_rootViewController被垃圾回收，导致出现bad access错误。

有任何类似的经验吗？

非常感谢！

你可能需要从错误消息中删除“这是无害的”信息，因为现在这样会使我在大量文本堆中找不到任何错误消息。 - MX D

抱歉！希望现在它有所帮助。 - Dhammini F.

请将错误作为文本发布，您可以单独复制并粘贴调用堆栈和代码片段。图像难以阅读。 - CodeSmile

尝试将 [UIStoryboard storyboardWithName:@"Storyboard" bundle:nil]; 改为 [UIStoryboard storyboardWithName:@"Main" bundle:nil];。 - user509981

这段代码对我来说运行良好：

#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;
    */
}
