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.
This is really frustrating because no matter anything I do my Navigation Title will not appear at all. The view is even the root controller for the navigation
I have tried the following:
Checking the box "Shows Navigation Bar" in Interface Builder.
Using the Simulated Metrics for a Navigation bar.
Programmatically Setting the Title, hidden to false.
Selecting the Navigation Item in the side and setting the title:
I have tried and searched everything, even tried on different computers, new projects and all have ended up in runtime looking like this:
It seems that your initialViewController is not the UINavigationController, so the viewController containing that UIButton is just showing initially since it is initialViewController. It is clear from the picture.
So first of all select your UINavigationController and set it as the initialViewController in your storyboard. This modification can make you happy.. Sorry if you have already done it...
In the storyboard you have to set its property "Is initial view controller" in the navigation controller Attributes Inspector.
I have a view controller that is the detail view of a table. When you click on the row of the table it takes you to the detail view. The detail view is embedded in a navigation controller such that there is a button at the upper left of the navigation bar that sends you back to the table. So far so good.
I now want to add an edit button to the right side of the navigation bar so that you can edit the detail view. My plan is this will add another view controller modally that lets you edit the details of the item. Standard stuff.
However, when I try to drag a bar button item from the list of objects to the navigation bar, it won't take. Instead, when I let go off the mouse button, it leaves the bar button on the tab bar controller at the bottom. (My navigation scheme includes different tabs and for each tab a table, detail view etc.)
Anyone run across this before and can suggest what I'm doing wrong or some sort of workaround to add the bar button item to the right side of the navigation screen. Do I have to add it in code?
Thanks for any suggestions.
I have got the same problem using Xcode6 and I noticed that UINavigationItem is added automatically for the first ViewController that you embed into NavigationController but for the subsequent ViewControllers, you will have to add it manually as follows:
In the Object library, find Navigation Item then drag it to your
2nd ViewController in the storyboard.
In the Object library, find
Bar Button Item then drag it the navigation item that you have created in the previous step.
Now you will have your Bar Buttons stuck to the top of your scene.
Update
The solution still works with XCode 7 but I wanted to add more descriptive photo. Just in case anyone is not really familiar with standard or technical names mentioned above. Notice the red arrows in the right, they refer to step 1, step 2 mentioned above. Also note the hierarchy of views on the left red rectangle.
Nasty trick:
Change your segue to push.
Set the content you need
Set back to show
Then the content will be editable and you have a non deprecated style for segue.
Your storyboard's view controller is likely missing a Navigation Item. You can drag one from the Object library, and drop it on your view controller.
You'll then be able to drag and drop bar button items onto the left or right side of the navigation bar.
i Solved it. drag in 'Navigation Item' to your detail view. than you can drag in the Bar Button Item.
The way that I fixed this issue was, instead of dragging a UINavigationController into the Storyboard and trying to add UIBarButtonItems to that, I dragged in a UITableViewController and then went to
Editor->Embed In->Navigation Controller
Which gave the same result as before except I could add UIBarButtonItems to both sides of the navigation bar with no issues.
Its actually xcode issue.
One trick which worked for me is to add the bar button in the VIEW FILE STRUCTURE ON THE LEFT.Instaed adding on the view directly.
Hope it helps you.:)
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.
I also had this problem, close and reopen the project worked for me.
I believe it's an XCode quirk. I had the same issue. I had to reset Xcode and shift the placement of things on the storyboard to finally get it to go. It's working now.
I think this is a bug of Xcode. In Xcode 8, change the segue in storyboard before the tab bar view controller to all its options (show detail, present...). Then back to show. Try to drag bar button items and modify tile. It works for me!
Did you try "cleaning" your project? I know that helps me sometimes (just go to "Product" > "Clean"). Or, alternatively, delete the navigation bar and try it again.
If you think it's a programming error, feel free to pass on your code. I'd be happy to help in any way I can. :)
You must reset xCode IDE . Close xCode and write the below codes at terminal...It will work.
rm -rf $HOME/Library/Application Support/Developer/Shared/Xcode
rm -rf $HOME/Library/Preferences/com.apple.dt.Xcode.*
rm -rf $HOME/Library/Saved\ Application\ State/com.apple.dt.Xcode.savedState
rm -rf $HOME/Library/Developer/Xcode
Same issue. I had a Table View Controller inside a Navigation Controller and many ViewControllers following further down the chain. A 'Navigation Item' was being created automatically for the FIRST root view controller and I could add a 'Bar Button Item' to this without a problem. Via the Storyboard, drag and drop. But thats all. On the following Table View Controller and further view controllers, even though they were within the initial Navigation Controller (auto generated back button appeared), storyboard would never let me add a Bar Button Item.
Wael Showair's solution did not work for me. Bar Button Items wouldn't appear.
I solved it programmatically in the end (Swift 2.0):
var testButton = UIBarButtonItem(title: "Test Button", style .Plain, target: self, action: "testButtonMethod")
self.tabBarController?.navigationItem.rightBarButtonItem = testButton
No extra Navigation item or Bar Button Item needed.
I was too facing the same problem.I was able to fix this issue by selecting the root view controller option and then in simulated matrix changed the Top bar option to Opaque Navigation Bar and was able to add the item on top of navigation bar.Hope this answer will help someone.
I had the same issue in xcode 8. I had to simply close xcode and reopen the project and then I was able to add the bar button to the Root Controller without any issues.
For XCode 8
There are many answers here. I tried some of them but I couldn't make it.
So I found my solution, just select your ViewController, go Attributes Inspector section and change the Top Bar to Opaque Navigation Bar and Boom. You will see navigation bar on your storyboard. You can change the title or add some item. If you don't want to keep Opaque you can change style to Inferred.
In Xcode 10, I just changed the type of segue going to this new view controller to 'Push (deprecated)', added the navigation item as it was allowed after I made this switch. If you switch back to your originally desired segue type, the navigation item will remain.
Instead of drag the "Bar Button Item" to the "Navigation Controller", drag it to the "Detail View Controller".
As you embed the Detail view into the "Navigation View", "Navigation Item" will be added to the "Detail View Controller". If you drag the "Bar Button Item" to the right side of the Navigation Item, the item will be included under the "Right Bar Button Items"
like Mark Lyons said , I used the same solution.
used push segue first
added the bar item
return back to show segue
done
In Xcode 11, you can drag a button to the navigation bar to create your bar button.
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.
