I've got a static table view as the main screen for my app right now, which is embedded in a container of the root view controller. the problem that i'm having is all of the items/pages that come from the original static table do not show a navigation bar in the storyboard. how to you recommend fixing this so I can use my UINavigationController in this container table. thank you.
Scenes in storyboard that do not come from a controller that has a navigation controller do not inherit the nav bar. To see what it looks like with a nav go to the scene in storyboard, then Attribute inspector from the right panel and change that controller to show a top bar instead of Inherit. This is useful when the code is adding the controller to the stack but there is no direct connection in storyboard from the controller to a navigation controller.
Now if your problem is that when you run the app app Segues from the static table push to controllers where there is no nav bar, this could be a result of embedding a tableViewController in a containerController. Maybe try setting a delegate on that TableViewController on the didSelectRow method and telling the Parent of the container to push.

Back when I first created the foundational layout for the app I'm currently working on in Storyboard, I did it in two steps:
Selected my View Controller and used Editor->Embed In->Navigation Controller.
Selected my View Controller again and used Editor->Embed In->Tab Bar Controller.
This was the resulting layout:
Question 1: Why do these steps create such an odd layout?
In this weird layout that seems to imply that the Navigation Controller is attached to the Tab Bar Controller as its parent, the only way I can get navigation items to display in the app (in the view controlled by the View Controller on the right) is by placing them in the nav bar of the Tab Bar Controller scene.
However, this creates various issues, including not being able to create an IBOutlet in my View Controller file for a custom view I drag into the title view slot in the Tab Bar Controller scene. Meanwhile, dragging anything into the navigation bar in the View Controller scene just makes it not appear in the app when it runs.
Question 2: How can I fix this layout so that I can control-drag from navigation items into my View Controller file? Or is everything actually correct, and I'm just trying to force something I shouldn't? (My intention here is to be able to set the custom title view's text in my View Controller code.)
Its obvious, if you want to embed MyViewController to NavigationController then you need to change your second step and need to embed NavigationController to Tab Bar Controller.
Selected MyViewController and used Editor->Embed In->Navigation Controller.
Selected NavigationController Embed with MyViewController and used Editor->Embed In->Tab Bar Controller.
It should look like this.
Note: You need to embed MyViewController to navigationController only if you want to perform push operation on this TabBarItem means with MyViewController other wise simply embed MyViewController to TabBarController no need to embed it with NavigationController.
The Problem
I'm relatively new to Swift and I'm trying to build an application that makes use of a UITabBarController.
What I'm trying to do is put a different navigation bar (or UINavigationItem) on each of the tabs in the UITabBarController.
For example, I want the UINavigationItem I set, with its bar button items, to appear on MyViewController instead of a back button to the previous view controller, such as shown on the image below.
The current layout on the Storyboard is as follows.
MyViewController on the sidebar:
What I've Tried
Someone suggested that I should embed each UIViewController (e.g. MyViewController) in a Navigation Controller. I've tried this and it doesn't work.
I've also tried to set the Top Bar to "None" in the Attributes tab of the options menu.
Thank you in advance for your help.
Here is how i did it,
UINavigationController -> UITabbarController
And then each "Tab" is in different Storyboard and every storyboard start with a "Navigation Controller". So yes every tab in different navigation controller this how you should do it.
Different storyboards because may be multiple people work on storyboard at same time.
Why TabbarController inside Navigationcontroller ?
I put the "TabbarController" inside "NavigationController" because some of the controllers i want them to be full screen, like hiding the "Tabbar" so for that i push them from main NavigationController.
//Out of context but may help you,
I have created an "Extension" of Navigation Controller to push a view controller on main navigation so that any of the tabbars (which are also inside navigation controllers) can easily use the extension to push any view controller if want to hide the tabbar.
Firstly, I would like to say that there are no errors with my code from a programming standpoint - it runs successfully, so a round of applause for that. However, the issue I am having is that when I run the application, it displays a black screen. I assume the issue has something to do with how I have set up the segues or something similar.
Hierarchy:
Reveal View Controller -> Table View
-> Navigation Controller -> Tab View Controller -> FirstViewController
Important To Note:
Reveal View Controller class is set to "SWRevealViewController"
Table View Controller class is not set.
Table View Controller segue ID set to 'sw_rear'
Navigation Controller class is not set <possibly the issue, but I cannot set the class to SWViewController as suggested by a thread online.>
Navigation Controller segue ID set to 'sw_front'
All other controllers have no set class.
I have discovered the solution. Hopefully others can learn from this.
When you create a project using a Tab Bar Controller as your base, an arrow will appear to the left of the Tab Bar Controller in the Storyboard. Moving that arrow to the Reveal View Controller (View Controller you set to the class of SWRevealViewController) lets Xcode know that you want to start your hierarchy from that object.
I had the same problem. What helped me resolving the issue was to remove the Navigation Controller that linked to the view (in my case was UItableViewController), and re-insert a new Navigation Controller (clicking the tableviewcontroller, Editor > Embed In > Navigation Controller).
I'm new to iOS, but I know the basis. I want to host 3 UITableViewController in a UITabBarController using the storyboard.
I dragged a UITableViewController from the object list(?) and control dragged creating a seguel. Now the tab shows successfully the table view controller.
The issue is the rows are taking the space of the status bar. So I want a navigation bar(?) there, with a title. Since I'm new to iOS I don't know the following:
Given the fact that UITabBarController is the first controller ever, the hosted UITableViewController should not have a back button, obviously. So is it correct to use a navigation bar to display a title (and possible add/edit buttons)
If so, I tried dragging the Navigation Bar but it doesn't work.
What am I missing or doing wrong?
hope this helps
actually it is done for another answer. but it will be handy to u too
You will want to add in 3 UINavigationControllers. Have each tab in the tab bar controller segue to a different navigation controller. Then set the root view controller for each navigation controller to one of the table view controllers.
I've spent the past few days searching on the web for a solution to my problem, however, I can't seem to find a problem similar to mine. I am using a TabBarController and on one of the tabs I have a segmented Control in the navigation bar that I would like to use to switch between view controllers. The problem is that when I present the second view Controller it appears over the tabbarcontroller. Is there anyway to keep the modally presented Navigation controller in the tabbarcontroller?
This is the first controller.
And this is the controller I am trying to present.
well we can't really comment unless we saw some code. But I think your problem may be to do with your view hierarchy. If I was going to build what you are attempting I would do as follows:
UITabbar controller that contains a custom navigation bar controller
The custom nav bar controller would contain the segment controller and have a protocol defined so that a delegate could be alerted when either segment was selected by the user.
The nav bar's root view controller would be a view controller that acted as a UIView container for the two screens you are displaying (friends and circle screens)
This root view controller would be the delegate for the custom nav controller so that it will know when the user selected a segment.
When the user selected a segment the root view controller would then switch between the friends and circles view controllers in the container.
To do the above have a look at the documentation for creating UIViewController Containers and working with delegates
Hope that helps!
