Question

我想知道如何在不使用UITableView到其根视图控制器的情况下在UINavigationController中设置UIViewController。对此有何帮助？提前谢谢。

Answer 1

您可以按照以下方式执行此操作：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // ...
    UIViewController *myViewController = [[UIViewController alloc] init];
    UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:myViewController];
    self.window.rootViewController = navigationController;
    // ...
}

如果需要，您可以替换myViewController的类和/或使用笔尖对其进行初始化。

Answer 2

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


   UINavigationController *nav=[[UINavigationController alloc]initWithRootViewController:[[OptionViewController alloc]initWithNibName:@"OptionViewController" bundle:nil]];
    self.window.rootViewController=nav;

    self.window.backgroundColor = [UIColor grayColor];
    [self.window makeKeyAndVisible];
    return YES;
}

Answer 3

它为我工作：

在窗口上设置tabviewcontroller，然后它就能正常工作。

UIWindow *window = [UIApplication sharedApplication].keyWindow;
        UITabBarController *tabVC = [self.storyboard instantiateViewControllerWithIdentifier:@"MyMainView"];

        [window setRootViewController:tabVC];
