Navigation Bar Not Showing after Adding NavigationController

Question

I have an existing UITableViewController that I've embedded in a NavigationController. However, the Navigation Bar is not showing when I present the view.

Presenting the TableViewController (its Storyboard id is: SelectServicesController) :

if let selectServicesController = self.storyboard?.instantiateViewControllerWithIdentifier("SelectServicesController") as? UITableViewController {
    self.navigationController?.presentViewController(selectServicesController, animated: true, completion: nil)
}

This is what it looks like when I build (nav bar does not show):

Answer 1

Adding this works for me:

self.navigationController?.isNavigationBarHidden = false

Answer 2

let storyboard = UIStoryboard(name: "Expense", bundle: Bundle(for: PTCAddExpenseViewController.self))


let controller =  storyboard.instantiateViewController(withIdentifier:"AddExpense") as! PTCAddExpenseViewController



let navigationController = UINavigationController(rootViewController: controller)

self.present(navigationController, animated: true, completion: nil)

Answer 3

Or it might be this!!

I had the same problem: the navigation bar was showing on the root view in Storyboard, but when running the Simulator - there was no navigation bar at the top of the views. This solved it:

Navigation Controller > Navigation Bar > UNCHECK Translucent (it is checked by default). This did two things:

1. My Navigation Bar shows on all subsequent views.
2. The topmost subview is now at Y=0, and not Y=64.

Answer 4

I encountered the same problem. I solved it by Changing the segue to the navigation controller that embeds the View Controller I want to display.

Hopefully it would work for you. Let me know if it is a bad practice.

I read in one of your comments you want to present the table view controller modally, with the navigation bar showing. We can do this using the Storyboard. From the view controller that should display this table view controller modally, Ctrl+Drag from the view controller to the Navigation Controller of the Table View Controller. Then, select Present Modally. Set an Identifier for the segue. Then, in your code for the view controller that is presenting the table view controller modally, call:

self.performSegueWithIdentifier("YourSegueIdentifier", sender: nil)

Another way to do this without having to use any code is if the modal presentation is being triggered by something like a button. Then, you can Ctrl+Drag from that button to the Navigation Controller and select Present Modally.

You're presenting a UITableViewController, which doesn't have a navigation controller as a parent (even though your Storyboard has it first, you're not actually using it).

You can fix this by doing something like this:

if let selectServicesController = self.storyboard?.instantiateViewControllerWithIdentifier("SelectServicesController") as? UITableViewController {
    let navigationController = UINavigationController(rootViewController: selectServicesController)
    self.navigationController?.presentViewController(navigationController, animated: true, completion: nil)
}

Or by setting the navigation controller as the initial view controller of the storyboard and then calling it like this:

if let selectServicesController = self.storyboard?.instantiateInitialViewController() {
    self.navigationController?.presentViewController(selectServicesController, animated: true, completion: nil)
}

So I just did this and at fist could not get it to show up at all. Then Figured it out, You just need to select the navigation controller and set it to be the ✅is initial View Controller

This is what your storyboard should look like

Then to make everything show up I added this to my viewDidLoad of the view the Navigation controller is presenting. This step is more optional.

    self.navigationController?.navigationBar.barTintColor = UIColor.redColor()
    self.navigationController?.navigationBar.tintColor = UIColor.blackColor()
    self.navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName:UIColor.blackColor()]
    navigationController?.navigationBar.hidden = false

And this is what it looks like

mmmm Red on black 🤓 Hope that helps you.

Answer 8

In your code, change this line

self.navigationController?.presentViewController(selectServicesController, animated: true, completion: nil)

to this

self.presentViewController(selectServicesController, animated: true, completion: nil)

Answer 9

My guess is Xcode is ignoring the fact that your table view controller is embedded in navigation controller when presenting your table view controller with the following code:

if let selectServicesController = self.storyboard?.instantiateViewControllerWithIdentifier("SelectServicesController") as? UITableViewController {
    self.navigationController?.presentViewController(selectServicesController, animated: true, completion: nil)
}

Instead, I would suggest you modify the Top Bar setting under Simulated Metrics to suit your needs or instantiate your navigation controller instead (the latter is preferred and recommended)

You're presenting the table view controller directly, not its navigation controller. If you mark the nav controller as the initial view controller (tick the "Is initial view controller" box in the attributes inspector), then you can instantiate and show it by:

if let selectServicesNavController = self.storyboard?.instantiateInitialViewController() as? UINavigationController {
    // if you're pushing it onto an existing nav controller
    self.navigationController?.presentViewController(selectServicesNavController, animated: true, completion: nil)

    // if not (and this is probably the case), set the nav controller as your window's rootViewController
    UIApplication.sharedApplication().keyWindow.rootViewController = selectServicesNavController
}
