I want to add a tab bar with three options (Home) the first view, (Incidences) with the second view, and (Info) with the third view, in the first view I have 2 buttons that shows the second and the third view.
What I have to do to add tab bar with these 3 tabs, always visible in the App?
I have this structure now:
New project -> Tabbed Application.
Replace the First and Second Views with your viewControllers. There will be no need for your left hand side view as the tabs will be your buttons
Each UIViewController in UITabBarController could be embedded in an UINavigationController at your convenience, that way you'll be able to use all of the features that you need.
Apple guideline for Tabbar: Tab Bar Controllers
Basically, you need to select the View Controller of (associated with) Tab Controller ▶ click on Editor menu item ▶ select Embed in and click on Navigation Controller
For correct flow of navigation using tabbar you need to bind tabbar
controller with View Controller first and then embed navigation
controller to tabbar. Similar way you can also embed navigation
controller to tabbar controller, but its not the correct flow.

I am creating an iOS application where I need to add a SideMenu and a UITabBarController, SideMenu and UITabBarController there purpose is to let the users navigates between different ViewControllers, I have 3 tab bar items in UITabBarController and in the SideMenu I have 5 items, when the user click on an item in the side menu I have to show the corresponding view controller
Question:
It's possible to add a ViewController without a TabBarItem to the UITabBarController, when the user click on the side menu item, I trigger the UITabBarController to select the corresponding view controller, or its not possible in UITabBarController I need to find another solution, if so please advice which solution is better.
In the picture above, These are my viewcontrollers but I need to hide the tab bar item for the last view controller and keep the UITabBarViewController behave normally when I programmatically select the last view controller from the side menu
If the ViewController of the side menu is different than the TabBar. You can PUSH the view directly in the controller that is selected in the tabbar in that moment.
So I have a UITabBarController and it has three buttons on the bottom in my iOS app. I want to add another set of buttons at the top but not quite sure on how to do this. I tried adding a UINavigationBar and a navigation button, and adding a view in to it, adding just the buttons, ect.... but to no avail. It won't let me add anything to the UITabBarController. Is there a way to do this?
Thank you very much.
the simplest way to that is to creat 3 buttons side by side and set their frame the way they divide the top of screen to 3 equals. it means u can create a tab bar with buttons manually.
but there's another way. i think this answer would help u
Positioning UITabBar at the top
To use the navigation bar you need a navigation controller. Now depending on your needs your tab bar controller should be inside a navigation controller or the other way around. If you want to be able to navigate away from the tab bar controller (have a screen without the tab bar) you should embed your tab bar controller into a navigation controller. If you only need the navigation bar for some tabs of the tab bar controller or you still want the tab bar to be visible all the time you should embed all (or just the ones than need a navigation bar) your root view controllers for each tab in navigation controllers. Finally if you do not need the navigation behaviour you could just put a regular view in the view controller that needs the bar at the top and some buttons in it and make them look the way you want.
You can embed a view controller in a navigation controller in a storyboard by selecting the view controller and the going to Edit->Embed in->Navigation controller.
Select the Any Tabbar ViewController then above the Menu -> Editor -> Embed In -> Navigation Controller its select, if you get the Navigation Controller then if you add the Navigation Button at Top of the ViewController, example :
I would like to add two tab bar icons (table view and collection view), as shown in the first figure below, to a regular ViewController storyboard (as shown in the second figure).
I have tried to embed the ViewController in the TabBarController (Editor -> Embed in -> Tab Bar Controller), but it seems to me that xcode only allows me to add one icon (Tab Bar Item).
You need one view controller per tab in the storyboard, then connect the tab view controller to those controllers using "relationship segue", "view controllers" (ctrl-drag from tab view controller to destination controllers, then select that).
In each controller you then can click the tab item and set an image, in attributes.
add tab bar item to the view controller u want to add in tab bar controller. and then control drag from tab bar view controller and the make "relationship segue as "view controllers"..
I am creating a tab bar iOS app. The tab bar view controller has two tabs, each of them connected to a view controller.
This how it looks:
I need to add more tabs to the tab controller. I am doing it at the storyboard as follows:
I add a new view controller.
I control-drag from the tab bar controller to the new created view controller.
A window opens and I select Relationship Segue-View Controller.
The segue from the tab bar controller to the new view controller is created.
I think that is the way to do it, but after that the tab bar controller doesn't show any tab icons, the tab bar becomes grey.
Like this:
I need to know what am I doing wrong.
First drag A TabBarController from Object Library you see that only two tabs with thier VC there.
to add more Tab Item in TabBarVC drag VC from Object Library
Then Control drag from TabBarVC to Newly VC then Segue relation pop ups
Select last one Relationship Segue -> View Controllers
I had the same problem until I added a tab bar item from the object library into the new view (settings its attributes on the right hand panel) and THEN ctrl dragged from the tab bar controller to the new view, creating a relationship segue.
If I tried to ctrl drag from the tab controller without first adding a tab item to the new view, it had the behaviour you described.
be sure to check the size of your icon image.
the tint of image added is grey by default. If you have a large sized tab bar image, it can look like the whole tab bar is greyed out for some reason. pic does not auto resize.
bellow process is follow in Xcode 9.4 for adding new item in tab bar controller.
1)Drag and Drop new Tab Bar Controller into sotrtyboard
2)It will show 2 item which connected with 2 view controller.
3)For adding third item button in tab bar controller
i) Add new View Controller.
ii) Right click on Tab Bar Controller and Drag into new view controller.
iii) one option popup will display inside that popup select "view controllers" options
It will create relationship link and will generate automatic item button in tab bar controller.
need to add/drag icon (from showing the media library) to the 3rd view controller, so that it can display properly.
Restarting Xcode 6.1.1 solved the issue for me while I was working on multiple projects.
go t0 library and choose tabbar controller then drag and drop after that take another uiviewcontroller and then click on tabbar and control and right click then drag and drop in the uiviewcontroller then you see some options where you have to choose in the relationship segue -> view controller

I am very new to Xcode and have encountered an issue with my app. I am trying to create a tab bar app. On one of the tabs I have a button that brings the user to a different ViewController. I want to have it so the user can select a button that would return them to the tab that had the button. I tried to set up an action from the button to the previous view (the tabbed screen), however the tab bar disappears. I hope this is makes sense.
Here is a link to a screenshot...
Easiest way to do this is to place a UINavigationController as the root view controller of the TabBarController. You can do this in storyboard by simply ctrl+dragging from the tabbar controller to the navigation controller and adding it as a relationship.
Here's an example using storyboards:
The next step is to set the third controller (in this case the table view controller) to your player view controller class.
Then, you can use the default back button and animation that comes with the navigation controller. If you prefer to hide the navigation bar at the top of the screen, then you can use your custom back button to call
[self.navigationController popViewControllerAnimated:YES];
You can also choose custom animations / segues, etc. but using a navigation controller to help you navigate screens is probably the simplest approach.
