更改实例化的ViewController

Question

我在Xcode中创建了项目，并删除了默认＆＃34; ViewController＆＃34;故事板中的类和默认视图。然后我将新的视图控制器放在故事板和表视图中，并创建了名为＆＃34; StartsController＆＃34;的新类。此时无法运行我的应用程序，因为它返回通信：

"-[UITableViewController loadView] instantiated view controller with identifier "UIViewController-BYZ-38-t0r" from storyboard "Main", but didn't get a UITableView".

如何选择我的＆＃34; StartsController＆＃34;要实例化控制器然后我会正确运行我的应用程序？

确保勾选了is initial ViewController

如果您想以编程方式执行此操作，只需将此代码放入AppDelegate.m中的application:didFinishLaunchingWithOptions:

中

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

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];

    StartsController *viewController =  ....;

    self.window.rootViewController = viewController;
    [self.window makeKeyAndVisible];

    return YES;
}
