Answer 1

Try this piece of code to set the navbar to not be hidden:

-(void) viewWillAppear:(BOOL)animated {
[[self navigationController] setNavigationBarHidden:NO animated:YES];
}

Good luck

Answer 2

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 :

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

Answer 4

除了@barryjones解决方案之外，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];

Answer 5

Further to the above answers, I have also struggled in a similar way with moving programatically between tabs of a UITabBArController.

Most posts I read suggested

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

var tabBarController: UITabBarController?

and then also in AppDelegate, I modified didFinishLaunchingWithOptions as follows:

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

tabBarController?.selectedIndex = 0
