I have looked at all the navigation bars on all the story board scenes of my app, and I have gone through all the view controller m. files and there is no mention anywhere of the navigation bars settings. The mystery is that I have two different pages, one where the back button is in lower case (back), another where it is in title case (Back), and other pages just have the cursor image < or nothing at all. If I click on the storyboard navigation bar area, it highlights in blue, and there nothing obviously there.
I cannot find where this has been defined !!
Any ideas?
In the storyboard check the previous view controller settings (the Controller before Controller with back button).
Select View Controller
Select Navigation Item
Select Attributes inspector tab (triangle icon)
Check Back Button field (there could be invisible symbols like spaces)

So, I am still in a learning phase of iOS programming using Swift and got stuck in one issue.
I have a Tab bar controller with options in the tab bar at the bottom.
In one of the tab pages, I have table cells, on click of each, I move the user to a WebView (Embedded in a UIViewController).
On the webView I have placed a back button, which is linked to the main Tab Bar Controller through a segue.
I am able to come back to tab bar controller successfully, but after coming back the tab bar at the bottom does not show.
Also, how can I remove the "
I have attached the main.storyboard screenshot for reference.Main Storyboard flow
I got it working by using the Segue type as "Show Detail" instead of just "Show".
I have a situation where I have enough tabs on a tab bar controller where the default system functionality has introduced the famous "..." more icon.
This is totally fine and I'm happy with the menu that is popped up when you tap it.
What I've noticed however is that a default transition occurs when selecting a item from the "more" menu (basically a slide right) to load the VC from the menu. Unfortunately this also introduces a lag on the accompanying slide "left" to get back to the menu.
My question is if this is default behaviour I have to live with or if this is something I can remove completely (ideally no transitions would be my preference).
Thanks,
Andrew
May this help you:
The More Navigation Controller
The tab bar has limited space for displaying your custom items. If you add six or more custom view controllers to a tab bar controller, the tab bar controller displays only the first four items plus the standard More item on the tab bar. Tapping the More item brings up a standard interface for selecting the remaining items.
Solution to your query:
Add only Five view controllers in your tabbar controller.
For last Fifth view controller, add more tabbar button icon (or any other image icon) manually and set a similar looking tableview (menu list).
Handle further navigation for remaining (Sixth onwards) view controllers, manually from tableview (row selection)
Storyboard Layout:
If you are looking for an alternate of more navigation, then you must customize tabbar controller and this may help you:
ZRScrollableTabBar: Scrollable tabbar items
IDScrollableTabBar: changing tabs with left and right swipe gestures on the tab bar.
JFATabBarController: Swipe tabs left and right
Ask me, if you want more clarification here.
I am following a tutorial on Udemy about Navigation Controllers.
The instructions are to drag a Navigation Controller onto the storyboard, and then drag and drop a Bar Button Item on the right of its navigation bar to segue to another view controller.
However, when I drag the Bar Button Item to its would-be position on the navigation bar, no drop-zone gets highlighted, and the button gets added to a random tab at the bottom of the screen.
I have tried finding references to this problem but all solutions are programmatic and given the wysiwyg nature of iOS development I would like to solve it through XCode UI.
Is there some setup I must change or is this an XCode 7 discrepancy?
Try to add a ViewController and then in Editor -> Embed in -> NavigationController. Then it should work.
I have solved my problem by dragging the Bar Button Item into the Document Outline, below Root View Controller.
This automatically creates Left Bar Button Items and Right Bar Button Items, which gives you an opportunity to drag the Item in the section of the controller you like.
I have an app with the start screen consisting of a table menu main which links to 4 different views, then three options to information pages.
Once on any of the main menu options are chosen, the view is shown with TabBar at the bottom of the main menu options. While the nav bar at the top has a back button leading to the main menu.
I built the storyboard which goes from a table view select to a single page. After that was working and passing data, I embedded the single view into a Tab Bar Controller and added a second page. It seems to be working as I would expect however the Tab Bar is not visible on the screen.
Can please anyone help?
I have added an image of the storyboard below:
Get rid of the navigation controller. There is no deed for it so far. Make the tab bar controller your root view.
If you need a navigation conroller within a certrain tab, or some or all of them, then add navigation controllers to those tabs (to the right in your storyboard).
Ok guys, novice here. I have a screen shot of storyboard I'm working on and I'm running into an issue where I can't name an item on my first tab bar because it points to a second tab bar controller. First I want to ask would this be proper use or should there only be one of these "types" per project. secondly, how the heck can I name the first tab bar item? I would do it normally by clicking on the tab element in the targeted view. Here's the screen shot.
Typically you only have one TabBarController in your project, and it is the root view controller.
And in storyboards, you can name your tabs not on the controller, but on the tabs under the separate views. Try double clicking on the label below your red, blue, yellow, etc views to name your tabs. Or, you can select the area below the view (which should be a TabBarItem) and the use the Attribute Inspector on the right to edit the title.
