I am new in iOS development and in Swift. I have a question. I added in one of the ViewController NavigationController. But I have some problems with back button cause it doesn't appear on other Views. I tried with self.pushViewController() and with self.present() but it doesn't work. If I mark in NavigationController Is Initial View Controller then everything is fine but I don't want it because then app starts with this screen(where I have NavigationController).
Please help me, what I should to add or to write?
This is an image of my storyboard
And this is what I have if I run and go to another ViewController, as you can see I don't have navigation bar and back button.
You got 2 options :
1) Add a navigation controller in the root ViewController, Hide throughout except the last one. Make sure you push the last VC so Back option will be there by default
self.navigationController.pushToViewController(BarCodeViewController)
2) Use a custom View on top of last viewController add a custom button to that view. But this time present it from previous ViewController
self.present(BarCodeViewController)
when back button clicked dismiss it by adding target to the button. self.dismiss()
I have a UITabBarController with many UIViewControllers resulting with a "More" TabBarItem.
One of those views has some editing functions I'd like to place in the UINavigationBar and I can replace the right and left button items, no problem. However, there seems to be an issue when you move that view controller where the navigation controller is no longer displayed. I believe I can solve the issue if I know from where the view is loaded from.
Here is my challenge I need some direction on:
What is the best way to check to see if the selected view is not being presented with the top navigation bar? Meaning, there is no "< More" on the top. That way I can display my own Edit button.
Any view controller can ask for its tabBarController. From there, it can get the tab bar controller's moreNavigationController. So now it can ask whether its parent is the moreNavigationController.
Should be able to check if there is a left bar button item using
navigationItem.leftBarButtonItem == nil
or
navigationController?.navigationItem.leftBarButtonItem == nil
depending on your hierarchy.
When I drag to the next view controller to add a segue the new view controller has no navigation bar with a back button. I thought that was the default when you add a segue to a new VC. I'm also not able to drag a navigation bar to the top of the table view controller. Am I doing something wrong? Thanks.
Maybe the problem is the kind of segue that you are you using. The Segue type should be "Show (e.g Push)". Click on the segue and in the right panel go to the "attributes inspector" (the 4th one). And here you can check the type.
A view controller like in your case only shows a navigation bar by default, when the view controller itself or one of its parents (connected by a push-segue) is embedded in a navigation controller. Obviously, the navigation controller must not have hidden the navigation bar.
So, you either forgot to put a navigation controller into play or your segue is modal and not push.
Well, it's two years since you asked your question, but when it happened to me, I realized it was because at one point, I had accidentally created my segue as a different kind of segue (a detail one, I think), but changing it back to a "Show" segue didn't actually change it's behavior. When I found the segue in my storyboard xml, it was listed as a "Show" segue, but with a different custom action that suggested it was going to do something completely different.
Anyhoo, deleting and recreating the segue in Xcode fixed it. I probably could have also deleted that custom action in the xml file, too.
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'm relatively new to iOS Objective-C development, and I've come across a problem that I can't find a solution to.
I have a Table View Controller, with two prototype cells on it, which populate fine. This Table View Controller is one of three Tab Views, and the View that sends to the Tab Views has a Navigation Controller. This means that the views within the Tab Views also have a Navigation bar. The bar works fine, in terms of the "back" button working as expected, and the bar being in position. However, (at least on the List View) the Navigation Bar isn't fully recognised - it's title doesn't appear, and the table cells start directly below the status bar, rather than below the navigation bar.
Here's a couple of screenshots showing the problem:
what appears in Xcode (what I expect to happen)
And then on the device, this is what actually appears - the Back button in place and working fine, but no title field, and the table cells start too high.
I've tried adding Navigation Bar's and Navigation Items, and while adding a Navigation Item allows me to put a title on in Xcode, it still doesn't appear on the device in testing. I also tried to add another Navigation Controller just before this view, but that didn't resolve the issue either, and it caused navigation problems further down in the heirachy.
Hope I've been clear enough, please say if I need to post more information - I'm relatively new to Xcode and so not sure what exactly is applicable and what isn't. Thanks!
please try this code, it might fix your table position
// Since in iOS7 the nav bar is translucent by default, so the table view starts at (0,0)
// you can either disable the translucent, which i don't recommend unless you really want to
// or just add 64 pixel on the top of your table view
[self.YOURTABLEVIEW setContentInset:UIEdgeInsetsMake(64, 0, 0, 0)];
and for the title, please try this
self.tabBarController.navigationItem.title =#"YOUT TITLE NAME";
Hope that helps..
Assuming your hierarchy as
NavigationController -> ViewController -> TabBarController -> ViewController1
-> ViewController2
-> ViewController3
If you want to hide navigation item in viewcontroller1, Add the following line
self.navigationController.navigationBarHidden = YES;
If you want to show title in viewcontroller2, Add the following line in
self.navigationController.navigationBarHidden = NO; //add this if you hide navItem viewcontroller1
[self.parentViewController.navigationItem setTitle:#"Title"];
If you want to hide backbutton and show title in viewcontroller3, Add the following line
self.navigationController.navigationBarHidden = NO;
[self.parentViewController.navigationItem setTitle:#"Contacts"];
self.parentViewController.navigationItem.hidesBackButton=YES;
Add this lines to viewdidAppear method instead of ViewdidLoad ,if you have problems inshowing when switching tabs.
I had the same problem, but what I did to create this problem was that my buttons action was connecting to the actual table itself and not the table Controller. I removed the modal action and created a new action to the table controller and it fixed the problem.
Try to click the Navigation Bar from your storyboard or nib.
Then add your title to the property.
