Try this piece of code to set the navbar to not be hidden:
试试这段代码来设置导航栏不被隐藏：
-(void) viewWillAppear:(BOOL)animated {
[[self navigationController] setNavigationBarHidden:NO animated:YES];
}
Good luck
祝你好运

According to apple docs, this won't be showing the navigation controller. In order to show the navigation controller you need to instantiate a navigation controller first, and then load the table view controller as shown below :
根据苹果文档，这不会显示导航控制器。为了显示导航控制器，您需要先实例化导航控制器，然后加载表视图控制器，如下所示：
LTBaseTableViewController *viewController = [[LTBaseTableViewController alloc] initWithStyle:UITableViewStylePlain];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
[self.window setRootViewController:navigationController];

I also struggled with this. Eventually solved by adding a Navigation Controller as defined in https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/AutolayoutPG/WorkingwithConstraintsinInterfaceBuidler.html
我也为此苦苦挣扎。最终通过添加https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/AutolayoutPG/WorkingwithConstraintsinInterfaceBuidler.html 中定义的导航控制器解决

In addition to @barryjones solution, you can directly push a table view controller using the navigation controller.
除了@barryjones 解决方案，您还可以使用导航控制器直接推送表视图控制器。
[self.navigationController pushViewController:yourTableViewController animated:YES];

Further to the above answers, I have also struggled in a similar way with moving programatically between tabs of a UITabBArController.
除了上述答案之外，我还以类似的方式在 UITabBArController 的选项卡之间以编程方式移动。
Most posts I read suggested
我读过的大多数帖子都建议
tabBarController?.selectedIndex = 0
however this would create the situation where the tab bar was no longer visible. Eventually solved by adding the following to the class in AppDelegate.swift
但是，这会造成标签栏不再可见的情况。最终通过将以下内容添加到 AppDelegate.swift 中的类来解决
var tabBarController: UITabBarController?
and then also in AppDelegate, I modified didFinishLaunchingWithOptions as follows:
然后也在 AppDelegate 中，我修改了 didFinishLaunchingWithOptions 如下：
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
tabBarController = window?.rootViewController as! UITabBarController
return true
}
You can then use the following line anywhere inside your various view controllers
然后，您可以在各种视图控制器中的任何位置使用以下行
tabBarController?.selectedIndex = 0
