Question

使用选项卡式ipad应用程序。我的程序构建但无法启动AppDelegate.m，

中此行中的错误

self.tabBarController.viewControllers = @[viewController1, viewController2];

此代码尚未编辑，即直接从模板编辑，并且直到现在才正常工作。视图控制器似乎启动，并在调试时在检查器中显示有效属性。我假设NSrange错误是指self.tabBarController.viewControllers数组，也许这不是真的。

抱歉，错误出现在我自己的代码中，请忽略。

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

    UIViewController *viewController_favorites = [[[FavoritesViewController alloc] initWithNibName:@"FavoritesViewController" bundle:nil] autorelease];
    UIViewController *viewController_project = [[[ProjectViewController alloc] initWithNibName:@"ProjectViewController" bundle:nil] autorelease];

    self.tabBarController = [[[UITabBarController alloc] init] autorelease];

    self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController_favorites,viewController_project, nil];

    self.window.rootViewController = self.tabBarController;

    [self.window makeKeyAndVisible];
}

Viewcontroller没有加载
