A typical Navigation-based app would have its MainWindow.xib contain a 'Window' and 'UINavigationController' -- this seems to work when a NavBar is your root view. If I want to show a NavBar view on launch based on one criteria and a TabBar otherwise, what's a good way to do this, utilizing Interface Builder for some of the layout of my views?
Workflow:
Default.png (Spash) -> NavBar with table or
Default.png (Spash) -> TabBar + NavBar with table
Are there any tutorials that would show some of this?
You could just add both the UINavigationController and a UITabBarController to the app delegate. In your appDidFinishLaunching just have the logic to decide which view to show and only add the correct view to the window.
In IB, you open your MainWindow.xib and you should have a Window and a Navigation Controller already. Add a TabBarController there also, then link it up to the instance variable in the app delegate.
At any time, your app delegate can add either of these views ad subViews to the main Window.

I have an iOS app written in Swift with UITabBarController with 5 UIViewControllers. Now, I have a bunch of UIViewControllers that are not part of the UITabBarController. I'd like to be able to show that same tabbar but I have no idea how to do that. Any clue?
More details: This is one of the View Controllers that the tabbar has. I use storyboard references and split my view controllers into separate more manageable storyboards.
So, the big picture:
There's no initial ViewController since I use storyboardId to get to the initial Navigation Controller. From there we have a ViewController embedded in the same Navigation controller. In that ViewController, there are 2 Container views - one of the size of the bottom ViewController that contains the "hamburger" button that toggles the other Container View which has an embedded UITableView in. When a specific cell is selected it should go to Profile ViewController that's not even in the same storyboard. The segue is set to be Push. Either way, doesn't show the UITabBar on the Profile ViewController
how you doing?
I don't know if I understood, but you are trying to show tabbar after going to another screen, right? If the answer is 'yes', try to change your segue to show(e.g. push).
-----Edit-----
You can do with two ways:
Presenting Modally -> using Current Context
Use push(e.g.) with a navigation view controller, you can also hide the navigation bar if you go to Navigation controller -> Attributes inspector -> Navigation Controller -> Uncheck Shows Navigation Bar
Hope now it works!
Best regards
I am unable to add tabbarcontroller in my existing view in my app. I dont want a tab bar application but tabbar in oneof my view in application.Can someone please Help me
To show a view that has got a tab bar in it, you don't need to have a tab bar base application.
Simply create a UITabBarController and then add its view to your main view (as a subview or how ever it is ok for you). You can create the UITabBarController either in IB or programmatically.
As the title suggests, I have built an utility based app.
The app consists (at the moment) of 2 view controllers + a model class hierarchy.
The thing is , as I'd like to add some features to the app , I would like to convert it to a TabBar based application.
As a first step , I would like the first view to be the first view of the tab bar , and the flipSideView to be one of the other tab bar items.
Is there any "standard procedure" / "grocery list" for such tasks ?
I'm sure some of you have encountered the same problem , and would love some advice on "slicing up" the app , and "wiring it up" after creating a new nib file for the main window (is that the first step ? )
Thanks in advance.
I would probably start as follows (assuming you are using Interface Builder and using the standard Xcode utility app template):
Edit your MainWindow.xib file and drag a Tab Bar Controller object into the top level of your view hierarchy.
The default tab bar controller in IB includes two view controller items as examples. Click the first one and change its class to be your existing Main View Controller class.
You can also set the icon and tab bar title for the main view controller item by adding the associated Tab Bar Item that IB has already added to the view hierarchy.
Do the same for the second tab bar item setting the class for the FlipsideViewController.
Delete the old version of your Main View Controller from the NIB file and also remove the IBOutlet property from the Application Delegate (you probably also have references to the main view controller in dealloc which should be removed).
In your App Delegate add an IBOutlet property for the Tab Bar Controller as follows (don't forget to synthesise the property):
#property (nonatomic,retain) IBOutlet UITabBarController *tabBarController;
In IB wire up the tabBarController outlet from the App delegate object to the Tab Bar Controller object.
Finally to get the tab bar controller to show up in place of the main view controller change the code in application:didFinishLaunchingWithOptions: to the following:
[self.window addSubview:self.tabBarController.view];
This should get the basic tab bar app up and running and you can add additional view controllers to the tab bar.
Since you no longer want to flip between the MainView and FlipsideView you can remove the references to the FlipsideViewControllerDelegate from the MainViewController along with the info button and its IBAction method showInfo. Likewise in the FlipeSideViewController you should remove the done button from the view and its IBAction method as these no longer make sense when used with the tab bar.
so, step by step :):
1. declare UITabController outlet in your app delegate.
2. in MainWindow.xib: first drag the instance of UITabBarController in document window, then make connection from app delegate to that instance. now you can set MainViewController as UiTabBarController's first tab viewcontroller, then set FlipsideViewController as UiTabBarController's second tab viewcontroller.
3. in app delegate's appDidFinishLaunching replace [self.window addSubview:mainViewController.view]; with [self.window addSubview:theNameOfUITabBarControllerOutlet.view];. that will do the work. sorry, I don't know your background, that's why I'm not very specific about performing a particular action I decribe, so let me know if you find yourself stuck
I am having a bit of trouble with my navigationController in my app. I am using the Kal Calendar component - https://github.com/klazuka/Kal.
I have created the view controller and have go it to appear in the correct position within in my app i.e. Click on a new tab and init the rootviewcontroller as the KalViewController and it sort of loads correctly but the back button is visible on the navBar when it should be the rootView and it is clickable 5 times before going to the true root, it's hard to explain but I have no idea what is wrong.
i have tried it with a table view and clicking on the first element in the tableView takes you to the calendar which works perfectly but this is not what I want/need in the app.
Thanks.
It sounds like you have both a UINavigationController and a UITabBarController. Make sure that the tab bar controller is your “main” view and that there are separate UINavigationControllers for each view controller in the tab bar. The different tabs’ view controllers should not be in the same navigation controller’s view heirarchy.
I have a tabbar application. Second tab had a drill down table list with Navigation Controller. I also want to implement a segmented control inside a tool bar that shows different table entries as per the selected switch in segmented control. I am a little confused as to how to implement this?
Screen-shot -
This is the view in second tab controller an instance of the generic UIViewController. Blue Background is a UIView that contains a segmented control (1,2,3,4). The steel blue navigation bar at the top is a simulated UI Element from Interface Builder. I need to put a navigation Controller such that it has a list table view that changed depending on the switch selected in segmented control UI.
I have following options
Add UINavController as root controller for second tab directly with table view inside it. In that case how do I accomodate the UIToolbar having segmented control?
I add UISegmentedControl as part of the view of Second Tab's view controller and add navigation based table view as another element to that view. Is this doable? How can I add a nav based controller to a UIView and control the frame so that it does not cover the UIToolBar.
I hope I am making sense. Please lemme know if you have any suggestions. Thanks.
This is how I achieved it. In IB, in MainWindow.xib where I have a tabbarController, I made the class identity of the second tab to a UINavigationConrtroller. Then I made the main view Controller for second tab that had the segmented control and the Table View as a rootViewController to the NavigationController. This functioning exactly as I wanted. Thanks all for your help.
you can add UINavigationController in place of UIViewController in UITabbarcontroller and Put your UIViewController who haveing UISegmentControl in UInavigationController who add in UITabbarcontroller
in reading its looks confusing but try to implement its work
Step 1: xcode-->new Project-->tabbar application
Step 2: open xib of main window select tabbarcontroller and open inspector. in that you able to see list of view controllers change their class to uinavigationController.
if you need uinavigationController in second tab then change only secong tab class to uinavigationController
step 3: create new uiviewcontroller. open its xib and add uitableview and segment control to that.
Setp 4: now expand tabbarcontroller and check your second tab have navigationcontroller now add your uiviewcontroller in navigationcontroller's viewcontroller
According to your requirements you can't avoid working with code - I mean that you can't set everything by connections in IB.
I would create a UIViewController (let's call it container) that will contain the segmented control and the navigation controller.
You should set the second tab to be a view controller and point it to the container.
Container's view (XIB if you want) should contain the segmented controller that will be aligned to bottom and a containerView that will fill the rest of the view and will have its IBOutlet.
Container should also have a navigation controller member that will be initiated in viewDidLoad.
The table view that you talk about should also be built in its own XIB and have its own view controller that will be set as root view controller to the navigation controller...
Tell me if it's too confusing / complicated...
