我的应用程序主要是在没有情节提要的情况下构建的。
但是,我仅为用户注册创建了一个。

此情节提要包括一个包含2个视图控制器的导航控制器。
第一个称为“ FirstVC”,第一个称为“ SecondVC”(这个问题将不会用于我的问题)。

我试图将其推送到AppDelegate.m文件中(尝试各种方式,请参见下文),但我的屏幕始终是黑色的。

尝试1

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {


    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    UIStoryboard *sb = [UIStoryboard storyboardWithName:@"FirstRegistration" bundle:nil];
    FirstVC *fvc = [sb instantiateViewControllerWithIdentifier:@"FirstVC"];
    UINavigationController *navController =(UINavigationController *)self.window.rootViewController;
    [navController pushViewController:fvc animated:YES];
   return YES;


}

尝试2

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {


    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    UIStoryboard *sb = [UIStoryboard storyboardWithName:@"FirstRegistration" bundle:nil];
    FirstVC *fvc = [sb instantiateViewControllerWithIdentifier:@"FirstVC"];
    self.window.rootViewController = fvc;
    return YES;
}


注意:我已在标识符“自定义类”部分中将FirstVC场景设置为FirstVC,还将情节提要ID设置为FirstVC。但是,我还没有接触过NavigationController的场景,应该将自定义类设置为UINavigationController吗?

ios - 如何实例化(附加) Storyboard 并将其插入我的应用程序?-LMLPHP

最佳答案

您可以尝试添加此行吗

[self.window makeKeyAndVisible];

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    UIStoryboard *sb = [UIStoryboard storyboardWithName:@"FirstRegistration" bundle:nil];
    FirstVC *fvc = [sb instantiateViewControllerWithIdentifier:@"FirstVC"];
    self.window.rootViewController = fvc;
    [self.window makeKeyAndVisible]; //**Add this**
    return YES;
}
