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'm working on my first iOS app and I'm realizing just right now that I don't have a navigation controller. Since I'm already pretty far in the app and not completely sure of how I would implement a navigation controller, I was wondering if I would need one in order to implement a search controller, meaning a UITableViewController with like a navigation bar on top.
To implement a Navigation Controller you just need to select the View Controller in storyboard then Click up top Editor -> Embed In -> Navigation Controller. You could also just add a navigation bar to the top of the View Controller you are using.
These are the two options for adding a navigation bar, however, neither is required for adding a search bar.
You do not need to add a navigation controller just to display a navigation bar. Navigation bar can be added to any UIViewController.
You can also add just the search controller in a navigation controller, without affecting your other view controllers. This will add a Navigation bar to the search controller and also allow you to navigate to (Push) other view controllers.
Using XCode, and either through Code or through the Storyboard, can someone please explain to me how to add both a Tab Bar and Nav Bar to my view controller while keeping both visible?
Thanks so much.
In your Storyboard, you should drag out a Tab Bar Controller and use that as the initial view controller. Then, you should embed each of the view controllers attached to the Tab Bar Controller inside Navigation Controllers (Editor menu: Embed In > Navigation Controller). Afterward, your Storyboard should look something like this:
The tab bar controller holds a tab bar and will manage switching between the other views attached to it, while the navigation controllers will place Navigation Bars at the top of each tab and help you manage navigation within the tab.
I am assuming you want something like this. Here is how I did it in Interface Builder:
Click your view controller.
Editor -> Embed In -> Navigation Controller
Reselect your view controller.
Editor -> Embed In -> Tab Bar Controller
Select the Navigation Controller
Check the box next to Is Initial View Controller
Hope this helps!
I need some help figuring out the anatomy of my app.
What I need is a tab bar that also have a top navigation bar. And then each view controller within the tab bar will need to have buttons that can transition in new views within this tab. Does that make sense?
So my question is, how should I set this up. Should it be a main tabarviewcontroller and then each view has a separate nagivationcontroller? Or should it be a navigation controller that has the tab bar as a root. And then just use that navigation controller to do any transitions within the viewcontroller?
Thanks!
Your main view can be a UITabBarController, and you can add your UINavigationControllers to the tab bar viewControllers array. Each navigation controller will have a separate navigation bar and function independently. Clicking on a tab will switch to the appropriate navigation controller.
I am developing a tabbed bar application using storyboards.
I am attempting to put in a back button one a view - but when I press to go back (from one view to another) the tab bar vanishes.
How can I ensure the tab bar stays there?
Just make sure you're adding the UITabBar to the main Navigation Controller or View Controller of Navigation Hierarchy.
You need to select Tab Bar on the Navigation Controller Bottom Bar under the Attributes Inspector, then set the bottom bar to Inferred for the rest of your pages (or Tab Bar if you want it to be different on any pages)
In my iOS application I have a tab bar view with three views. I would like each of those views to have a "navigation" bar at the top. I would like the navigation bar to have a left bar button item which has the same functionality across all three views, and then a right bar button item which is unique to each view. How should I build this?
In each tab, put a UINavigationController. That's a separate one for each tab.
Set the root view controller of each navigation controller to a view controller that manages the content view you want to display.
You can set the left button item of each of the three navigation controllers to the same thing, and set the right button item to something different.
