Answer 1

我正在通过一本旧书研究使用 ObjC 进行 iOS 开发（出于个人原因），当我覆盖AppDelegate.m中的didFinishLaunchingWithOptions时发生此错误，所以我通过设置全局导航控制器来解决，如下所示：

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

    // Override point for customization after application launch.

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

    RootController *rootController = [[RootController alloc] init];

    UINavigationController  *navController = [[UINavigationController alloc]initWithRootViewController:rootController];

    self.window.rootViewController = navController;

    [self.window makeKeyAndVisible];

    [rootController release];

    [navController release];

    return YES;
}
