I don't know why but my navigation bar is missing from my ios simulation.
Anybody know where might be the problem?
Yes I have "Shows Navigation bar" and I don't have any warnings.
I wanted to try "Update frames" but I don't have this option available.
I am using Xcode 7.3 and Swift.
Thank you
You can solve by embedding a navigation controller:
As other people have said in the comments without showing some code or screenshot of IB it's hard to find out where the problem is... But here's some things to checkout.
Are you sure your view controller is embedded in a UINavigationController?
If you are using Storyboards you should have something like this:
In code instead you might have set the window.rootViewController property in the AppDelegate to the content view controller rather than the navigation controller which is supposed to contain it.
Its depend how to embedding navigation controller but you can try to embedding navigation controller following below way and than run application and check in simulator : Go to Editor in xcode -> Embed in -> Navigation Controller.
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:
My Navigation Bar shows on all subsequent views.
The topmost subview on subsequent views is now at Y=0, and not Y=64.
There are two possibilities.
1) May be you didn't Embeded navigationcontroller before your viewcontroller. so, add Navigation controller with go to
Editor -> Embededin -> Navigation controller.
2) If you have add navigation controller but May be you have set NONE as topbar of Viewcontroller.

I'm in XCode 7.2.1 and I am trying to make a view that is reusable and should have some custom elements in the navigation bar.
If I would add a view to my storyboard, connect it via a segue to the navigation controller and make sure there is a "Navigation Item" in the view, I could see the navigation bar and edit my items in it.
If I manually add a Navigation Item to a XIB however I can't see anything. Even if I switch in the simulated metrics settings Top Bar to something else than Inferred or None.
I don't want to use the storyboard, if possible. Is there a descent way to make the navigation item visible and edit it?
Thanks in advance.
I don't think you link your View Controller correctly with Navigation Controller. When you link it, you should choose with root View Controller. If you link it correctly, you don't have to add NavigationItem manually.
By the way, you shouldn't do the customization for Navigation bar directly in xib. All you can do is only to set the Title, Prompt and Back Button text.
Do it in code! I think you won't have different styles for navigation bar in different views, right? That would be too silly.
I can't solve this despite my best efforts. I also consulted the Apple documentation and several related questions here and still I have a mental block on this.
Using Xcode 6, I embedded a table view controller in a navigation controller and could set the title of the navigation bar in the table view controller, but not in the two view controllers that are connected to the table view via segues.
I did think there was a navigation bar on these two view controllers because after I embedded the table view controller in the navigation controller, it blocked out my topmost textfield in both. I repositioned that so that isn't a problem, but in storyboard I still don't seem to be able to click inside the navigation bar to add a title and now having added a navigation bar manually to test it out, I can see that there is only one navigation bar in document outline.
So do you simply have to set the title of the navigation bar programmatically or with an IBOutlet or some such? Doesn't seem like you can click into it in story board.
I am pretty sure this is a bug in Xcode... I have experienced the same issue and most of the time it was solved by restarting Xcode.
** In addition you may be able to get it solved by doing:
Drag a Navigation item from the objects pane into the viewcontroller or tableviewcontroller. This seemed to work for me. I did notice that the navigation area was missing from the "Document Outline Pane".
I hope this helps.
I had the same problem while following apple's swift guid. Dubble-clicking the "navigation bar" did nothing for me.
How I solved it:
1: Select the "navigation item" from the document outline pane.
2: Open the attributes-inspector.
3: Select the title field and write the title here instead.
I had the same problem. What worked for me was to select the controller that I couldn't set the title on, click editor -> embed in -> Navigation controller.
Then you should be able to edit the title and when finished, delete the navigation controller and reconnect the two original controllers.
The screen that was previously embedded should now contain the title you created earlier.
Try to set title programmatically -> self.navigationItem.title = #"REGISTER";
place this is your prepare for segue:
[segue.destinationViewController setTitle:#"New Task"];
Connect your Navigation Item to your class (i.e. UIViewController), and access it's title programmatically by writing the following within your viewDidLoad:
navigationItem.title = "whateverTextHere"
You can also set the view controller's "title" property instead, which will automatically set the title of a navigation item or tab bar item.
By selecting the view controller in the storyboard, you can set the title under "View Controller" in the Attributes inspector (Xcode 9):
Be sure to use a Relationship Segue, not a Manual Segue when embedding controllers.
Update to this issue if someone else need it:
Make a segue between ViewControllers
Pick Kind option as Show(e. Push)
Than change this Kind option on some deprecated - ex. Push
Now you can edit your tittle and navigation items from storyboard
Remember to change Kind option again on what you need.
None of the answers worked for me.
This worked:
Delete nav connection
Ctrl drag a new nav connection
Make it a show connection
Now you can edit the title
Delete the nav connection again
Create the original nav connection type again
It seems that this is indeed a bug in IB 🙁
I have a UITabBarController to whose controllers I would like to attach navigation. So I inserted the NavigationController as the entry controller, and the tabBarController as its root. All seems working fine, but for the tabBar. Basically it does not show, albeit the StoryBoard I attach seems to say differently. I also attach the Account Screen not showing any navigation bar nor, of course, any back button.
Thanks,
Fabrizio
Just a quick answer. I think you should put UINavigationController inside the TabBarController instead of the other way round. It will solve most of your problems.
Steps: Editor -> Embed in -> Navigation Controller
See the below screen shot on how to add a Navigation Controller to a View Controller.
You are following wrong approach, IOS does not allow you to use tabbarview controller as root of navigation controller, it always display black screen. I have faced same problem and as a solution i have added navigation bar after tabbar controller. Yes it becomes difficult to manage, but you can use that way and it will work.
If you use programmatic approach instead of storyboard then it is possible, see this link
Even you can try from Editor option of XCODE, select tabbar controller you have added from storyboad then go to Editor->Embedded in, you will see that navigation bar controller is disable.
This is also give you idea that it will not work.
I have set up a view controller in Storyboard which is embedded in a navigation controller. In this nav controller I have checked Shows Navigation Bar and Shows Toolbar and enabled a navigation bar and toolbar in Top Bar and Bottom Bar respectively in Simulated Metrics. I then "Show e.g. Push" segue from the view controller to another view controller. On both view controllers I've set up Simulated Metrics the same way, so both the navigation bar and toolbar are visible on all three controllers.
The problem is, I can add bar button items to the first view controller to both the navigation bar and the toolbar, but I cannot add a bar button item to the navigation bar on the second view controller. When I drop a button on the navigation bar, it's added to the toolbar instead. And I cannot double click the nav bar to add a title. In the outline I see there is no navigation item on the second view controller, but it is there in the first view controller.
I can probably add buttons to the navigation bar programmatically, but I want to do this visually in Storyboard. My question is, what is wrong with this setup, or is this a bug with Xcode?
For XCode 6, the UINavigationItem for the 2nd view controller onwards is not added automatically on the View Controller Object inside the storyboard. You will have to drag the UINavigationItem onto the Navigation Bar for that view Controller Object before adding UIBarButtonItem on top of it.
I am not sure why it is designed that way. I only discovered about this a few weeks ago.
If you have a ton of view controllers and very little custom auto-layout stuff in place, you can disable size classes, then re-enable it will add all missing nav bars across your storyboard.
Obviously not recommended if you have a ton of custom auto layout stuff linked up.
If you have just a single UIViewController that's missing a nav bar, just drop a UINavigationItem onto it.
If you're using Xcode 7 beta 4/5, try restarting Xcode it solved the issue for me
I just bumped into this issue and it seems to be affected by the segue that shows the view controller.
If "Kind" setting in segue is "Show (e.g. Push)", it's not possible to drag the item to top right corner. However, if you explicitly change "Kind" setting to "Push", this can be done.
Edit: actually I just noticed that "Push" is deprecated. Not sure what Apple is thinking here. However, you can just change it back to "Show" after adding the button and it seems to work :D
For second view controller in hierarchy, you can setup title in attributes, without adding "navigation item"
I think it is a bug. I had the same problem.I fixed this problem by disable the size classes, then enable it.
You can disable and enable the size classes in Interface builder doc.
It's very simple. You just need to use navigaitonItem first as the holder of the buttons and then you can add barButtonItems on top of that.
I enabled o UITabView on the bottom of the screen, and that works, but the rest of my buttons on the app screen suddenly stopped working. Would anyone know why that might happen? I was using push segueys for them.
I think the issue may be that originally I have a NavigationController that I use on the app, and then the UITabBar controller interferes with it.
Thanks!
As per Apple recommendation, UITabBarController should only be the root controller of an app. I think what you are doing is you are having the UITabBarController nested in your UINavigationController, and that won't work.
You can instead select your navigation controller and embed it in a UITabBarController. (I don't have XCode with me now, but I think there's an option in the menu called Embed in -> Tab Bar Controller. You can search for it in Help.)
(If you need the tab bar controller to be nested under nav controller, I believe you need to use some buttons to fake its effect.)
If you only need a tab bar but not tabbar controller, then don't use tabbar controller.
