I'm new to iOS development, I just have UITableViewController in a storyboard. I would like to add a top bar to it with some buttons, how to do that?
Notice, I'm using UITabBar that is created by "Storyboard" and my ITableViewController is one item of the UITabBar.
When you create the UITableViewController, do the following:
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:tableViewController];
and then instead of setting the table view controller as the view, set it to the navigation controller. Inside your table view controller, you can set the left and right buttons for the navigation bar to UIBarButtonItems (ask me if you want to know how to do that).
Select your UITableViewController and go Editor > Embed In and choose a navigation controller.
You might look at using the UINavigationController.
https://developer.apple.com/library/ios/DOCUMENTATION/UIKit/Reference/UINavigationController_Class/Reference/Reference.html
If you do not want to use UINavigationController, then what you could do is create a view that has the "top bar" that you are looking for, then add the UITableViewController's view to your new UIView.
You need to create an UIViewController, not a UITableViewController, and then place the elements you desire however you want (in this case, a Table View and a UIToolbar).

As my screen have static options, so I created a screen with static cells from UITableViewController class instead of UIViewController
Now When I'm trying to add the Navigation bar from storyboard it never adds above UITableView. Always added at the footer of the table view.
Can we add without programmatically?
Please refer screenshot:
Appreciate your help!
Thanks
In Storyboard, you can't add any other view at the same level of the TableView in TableViewController, so adding UINavigationBar won't work here.
You can show navigation bar using UINavigationController:
In Storyboard first, select your Table View Controller.
Then Open Editor menu, and select Embed In option, and choose Navigation Controller. You will get your navigation controller pointing to your tableview controller.
To solve your problem, you can embed your UiTableViewController in a UINavigationController from storyboard.
Just add a UINavigationController on the storyboard and drag to your UITableviewController and set it as either root or push.
You dont have to manually add the UINavigationBar.
Hope this helps.
A simple way is that you can embed your UITableViewController in a UINavigationController:
Select your UITableViewController in the Storyboard.
go to Editor => Embed In => Navigation Controller
The second solution is to add it programmatically, as you just said.
i am wanting to add a barButtonItem onto a tabBar so i don't have to use a navigation controller at the top of the screen.
My ViewControllers are embedded in a tabBarController:
And i want to add a barButton on each viewcontroller e.g.:
and them implement some code like:
func tabBar(_ tabBar: UITabBar, didSelect item: UITabBarItem) {
if item.tag == 4 {
}
}
to run a function when this button is tapped.
problem is this button isn't showing on the tabBar when the app is built.
i was hoping this would achievable without having to create a custom tabBar.
I don't quite understand what the problem you're describing is. Are you trying to add a 'Logout' button at the top right of your screen by only using a UITabBarController? Why are you against using a UINavigationController? It's incredibly easy to implement using storyboards (which it looks like you're using anyway).
Apple even has a page on how to implement a UINavigationController within a UITabBarController here: https://developer.apple.com/library/content/documentation/WindowsViews/Conceptual/ViewControllerCatalog/Chapters/CombiningViewControllers.html
Key information here:
To create a combined interface with three tabs that contain custom view controllers and one tab that contains a navigation controller:
Create three custom view controllers, one for each tab, and a navigation controller.
Select the three custom view controllers and the navigation controller (only the navigation controller scene, not it’s root view
controller).
Choose Editor > Embed In > Tab Bar Controller.
Display the tab bar controller as the first view controller by selecting the option Is Initial View Controller in the Attributes
inspector (or present the view controller in your user interface in
another way.)
According to Apple Documentation,
UIBarButtonItem - A bar button item is a button specialized for
placement on a UIToolbar or UINavigationBar object. It inherits basic
button behavior from its abstract superclass, UIBarItem. The
UIBarButtonItem defines additional initialization methods and
properties for use on toolbars and navigation bars.
Since you're against putting a Navigation Controller in your project, a UINavigationBar is not implemented which is what UIBarButtonItems are for. If you want to implement your Menu Button on top of your screen in one of your view controllers. Why not just use a UIButton as inside a UIView like this?? The blue background is just a regular UIView with UIButtons inside of it.
I have the following hierarchy in my app: UITabBarController to many UINavigationControllers. Each navigation controller has a UIViewController.
I’ve split this up so that each UITabBarController’s child view controller is linked via a storyboard reference. In each of these references there’s a UINavigationController as the initial view controller.
Again some of these other storyboard references are split up too, where one of the UINavigationController’s child view controllers also uses a storyboard reference.
These UINavigationController’s child view controllers in the new storyboards do not carry across the UINavigationController style. Unlike the UITabBarController which does take across the UITabBarItem and shows them in the UINavigationController.
Is there anything I can do to see the navigation item of these UINavigationControllers so I can add bar button items in IB?
It's straight forward really; just go to Editor > Embed In > Navigation Controller and embed your view controller in a UINavigationController. You can then select the UIBarButton items under the Object Library in xCode, drag and drop them to the navigation bar on your View Controller and voila!
You can then delete the UINavigationController when done with adding the UIBarButton items to your VC; those bar button items will still be referenced and shown in the final product when you run it.
In Storyboard go to the Attributes Inspector for the Controller you wish to add the navigation bar and click on top bar drop down instead of it saying 'inferred' click on 'Translucent Navigation Bar'
I've tried a lot to get this done.I don't want want to use addsubview or uitabbarcontroller. I want to switch the view when I tap on different tabs and tabbar should stay there. Thanks a lot in advance.I m a newbie.I want to use uitabbar not uitabbarcontroller.
A simple approach would be to wrap the view controllers you are inserting in UITabBarController in a UINavigationController then you can simply push your new view to that UINavigationController and the tab bar would be always visible!
For more details refer Apple Docs
Edit:
If you don't want to use UITabBarController then you need to do 2 things:
Add the tab bar View to UIWindow that way it would be always visible.
Scale/adjust the views in your view controllers to leave space for the tab bar
I have a SplitViewController which has two UITableViewControllers - one master/root one detail. Everything works swimmingly.
I have a UIView which is shown on the detail view controller before the user selects an item in the root view controller. It's set up like this:
[self.navigationController.view addSubview:makeSentenceHelperView];
[self.navigationController.view bringSubviewToFront:makeSentenceHelperView];
The detailViewController is set up like so:
UINavigationController *detailNav = [[[UINavigationController alloc] initWithRootViewController:detailViewController] autorelease];
Where detailViewController is a subclass of UITableView.
The problem is that this subView hides the buttons and navigation bar from the detail view controller's navigation bar - which is a problem when you launch the SVC in portrait mode (there's no way to select a root item with the root popup).
How can I present the view inside the navigation controller, so that the navigation bar and buttons appear in the detail view?
Don't make detailViewController a subclass of UIView, instead go with UIViewController. So your splitView array will contain a instance of UINavigationController(rootVC) and other of UIViewController (detailVC).
Add a toolbar on the top of detailViewController and in landscape mode left side will be covered by your UITableView of rootVC and you will be able to see toolbar where you can add some button to its right side (will probably serve as navigation bar..:) . Rest of the things can be handled by UISplitViewControllerDelegate.
To fix this I added a UINavigationController to my helper UIView, and added a UIButtonBarItem to call the popover for selecting a new item in the master view. It seems really simple in retrospect. The only tricky bit will be making the UIButtonBarItem hide when in landscape.
