I have a UINavigationController in Interface Builder in a storyboard. I've added two UIBarButtonItems to the first UIViewController. They display just fine. How can I add them to the second UIViewController which is navigatated to? On that view controller, I only see the Back button.
When I try dragging a UIBarButtonItem to the top of the second view controller, the button ends up at the bottom of the scene for some reason. It is not displayed when running the app.
Edit: I should have mentioned that I know how to do this in code, but not in Interface Builder.
To add further informations about my comments concerning navigation item :
Here is a simple project with a UIViewController embedded in a UINavigationController. A second UIViewControllercan be pushed via the Next button.
If you select the next button, you can see in the hierarchy that this button is embedded within the group Right Bar Buttons Items, which is embedded within the First object. In fact, First is a UINavigationItem automatically added to your view controller when it was embedded in the navigation controller.
But the second view controller (the pushed one) doesn't have this navigation item since it isn't directly embedded within a navigation controller. Simply drag and drop it from the Object Library to your view controller.
#Slack, As i said earlier just drag and drop 2 "bar button item" in your navigation bar.

I am working in a swift 3 xcode 8 project, and I have an issue.
I have some view controllers.
In the first one I've inserted a navigation controller, which gives me the "back" button when I am in another view controller. So I can go on and back to the first viewcontroller.
The thing is, lets say, when I am in the third view controller I'd like to insert a button, but appearing just in this viewcontroller in the navigation controller.
I've tried adding a bar button item but it doesnt work because the navigation controller only appears, in the storyboard, in my first viewcontroller.
So how can I add buttons to the navigation controller, in another viewcontrollerS?

Drag a Navigation Item into your third view controller. Now you can add bar button items to that.
I have a ViewController, which is connected to a UINavigationController, that has two buttons, each one for a specific UITableViewController.
I drag and drop from each button to its corresponding UITableViewController and select show for the seque
the problem is that I can tap on the top of the first UITableViewController and set the name, but I can't do that on the second UITableViewController. my question is that normal?
please notice that the second UITableViewControlelr (Subtitle Cell Table View Controller) doesn't have a come back symbol like the other two do
as I am totally aware that I might need to wait because on swift still not a lot of programmers as in Android, i hope you help me

I will add screenshot to show you my problem
this is the MainViewController
This is the first UITableViewController (as you see it has a title, which is players)
This is the second UITableViewController (my problem is here I couldn't add a title for it by clicking on the sense on my storyboard)
You need to drag a UINavigationItem into UITableViewController.
Navigation item belongs to a view controller and it is used to show the view controller title on the navigation bar. Every UIViewController has a Navitagtion item assigned to it. Its generated at runtime.
When a View Controller is pushed onto a Navigation Controller, the navigation controller gets the information for title view form the view controllers's Navigation Item.
So if you want to be able to change the title of a View Controller from storyboard, you need to add a Navigation Item in ViewController.
UINavigationController cannot have title changed, because, title belongs to ViewController, and navigation controller just show the relevant title onto its navigation bar.
When I try to add a UIBarButtonItem to my UIViewController, nothing shows up at run time.
What I did:
I started off with a brand new single view project.
I dragged a UIBarButtonItem into the view controller.
I can now see and customize the item in the storyboard, but when I run it, there is no toolbar.
Note: the Bar Button Item appears as a direct child of View Controller.
How can I get the UIToolbar to appear?
Adding toolbar items as direct children of the UIViewController corresponds to the toolbarItems property of a view controller. The documentation states:
If this view controller is embedded inside a navigation controller
interface, and the navigation controller displays a toolbar, this
property identifies the items to display in that toolbar.
So, you must do the following:
Embed the UIViewController in a UINavigationController (e.g. select the UIViewController in the storyboard, choose Editor > Embed In > Navigation Controller).
Select the UINavigationController and check the box that says Shows Toolbar (this is the similar to calling self.navigationController.toolbarHidden = NO in the view did load method).
Optionally, if you want to restore the behavior where the navigation bar wasn't visible, then uncheck the Shows Navigation Bar property.
An alternative approach is to not use the toolbarItems property, and instead add your own toolbar and maintain it yourself (e.g. add an IBOutlet and interact with it that way).

My problem is, my app starts with a single view, it shows a menu made with buttons that takes me to different places, one of this places is another kind of menu, but this menu is a tab bar menu, so the thing is, I made a new file with its .xib, I added the tab bar controller, and i Linked all the sections of my tabs with its viewcontrollers...
this means that I have my first menu ready, I have my view controllers ready, I have my menu on the tab bar ready....
so my problem is...
how can I go from my single view (the first view that I see and that doesnt include a tab bar), to the new screen with tab bar controller in it after pressing a button???
help me please
Note: I'm using XCode 4.2 and I'm not working with storyboards (requirements of the app)
You have three options to show your viewController content :
1.using presentModalViewController:
2.add the viewController view as a subView to the current viewController. in your case : [singleViewController.view addSubView:tabBarViewController.view];
3.or if your simple ViewController is the navigation root viewController you can push other viewControllers to its navigation stack. (as #roronoa zorro described).
You might have added all the next viewControllers on the taBarController so if you have want to tabbar on to next screen you simplr have to push the tabbarcontroller on the navigationcontroller.
[self.navigationController pushViewController:TabBarControllerObj];
I have an existing ios5/xcode 4.2 app, and I want a button to open a view that will display a list of items, and have a back button and an add new button.
I thought I could achieve this by adding a button to the main view controller, then dragging in to the storyboard a new UITableViewController, then embed a UINavigationController (editor->Embed In->Navigation Controller).
Then i right clicked on the button, dragged it to the navigation controller, and thought, ok this should work.
However, there is no back button, and xcode will not let me drag one in, nor will it allow me to drag in the button bar item "[+]" for the link to add new.
When I run the app, the list shows, of course I have no way to go back to the view controller with the button on it.
What am i doing wrong? - thanks.
(my question is similar to this
but for xcode 4.2)
Embed the main view controller, not the new one, in a UINavigationController. This should add a simulated UINavigationBar to the main view (if not, set one up under Simulated Metrics). At this point you should be able to drop in a UIBarButtonItem to the main view's simulated bar.
Next, draw a connection from your button to the new UITableViewController to set up a push segue. At runtime, the back button will appear in the bar automatically.
Make sure when you try and drag the items into your view controller that the storyboard is zoomed in. XCode won't let you add items if you are zoomed out.
