I have a navigation based app, in one of the screen I now want to add a tab bar. Can any one please share code snippet on how I can do that. Thanks
the common way is to add a navigation view to one within a tab view, not vice versa. as far as i know it is not possible to add a tab bar to a navigation view.
You could call a modal view that uses an underlying tab bar. Another idea is to use the tab bar for the whole app and hide the bar for the views where you don't want it to show up.

In our current project we had a tab bar controller, and every corresponding view had a tab bar controller. Lately we decided to use another navigation approach and we removed the tab bar controller.
Unfortunately the tab bar items in the views seem to be unremovable in the SB. In the running app they are not visible. We even tried to reconnect them to a tab bar controller, but no avail. Also, they don't show up in the document outline.
Is there anyone who can spread some wisdom how to remove them?
Try making the bottom bar to none in the attribute inspector of viewcontorller
I have added an UITabBarController. My requirement is to display a view with tab bar controller. but that view is not part of the tab bar items. For example my tab bar contains 3 tabs
contacts
camera
history
Generally if we add tabbar controller contacts will be get selected and that view will be displayed automatically. but i don't want in that way...
i used [tabBarcontroller setSelectedViewController=nil];
i am able to get a tab bat with non of the tab get selected. but when i am trying to select a tab item it's not working.. I think i set the selectedViewController to nil. is there any other way to achieve my requirements...?
please explain your answer clearly.. i am new to iphone app development..
Present a view controller which is not a part of your tab bar controller and put a tab bar image/buttons at the bottom of it which resembles your tab bar. When you receive a button pressed message from within that view controller, show that tab on screen.
How can I submerge and reveal tab bar in iOS like the Groupon iPhone app does?
Use a pseudo tab bar if you don't want to mess with the actual tab bar framework, subclassing etc. For example, put a segmented controller onto a view that is no bigger than the controller, size the view and controller to the size of a tab bar and just animate the origin of this custom view. Would be pretty easy and you could get it on and off the screen whenever desired with similar functionality to a tab bar.
Just one option...
My application consists out of a tabbarcontroller and inside i got multiple navigationControllers. Now i want to hide the bottom bar of the tabbarcontroller from the start because the buttons on the bottom bar lead to features inside the application which are just not ready yet so i dont't want the user to see them. How do i do this?
Thanks in advance!
A couple of options:
Set hidesBottomBarWhenPushed=YES on one of the controllers in your navigation controller. I'm not sure if this works on the root view controller of a navigation controller.
Hide the tab bar items by changing UITabBarController.viewControllers. I'm not sure if it lets you have a tab bar with only one tab, but it ought to.
Set the tab bar controller's delegate (see UITabBarControllerDelegate). In – tabBarController:shouldSelectViewController:, return NO if it hasn't been implemented yet.
I guess I'm just really looking for some advice on how to approach my problem.
So far I have an application with a navigationcontroller that has a table view.
Every cell in the table has a text field and image and a disclosure button.
This is sort of my main menu option navigation screen.
When a user clicks a disclosure button I would like to go to a sub view of a tab view controller. The tab view will show different content depending on what cell is selected.
I'm guessing it would have something to do with the accessoryButtonTappedForRowWithIndexPath but after that I'm a little lost.
I've only ever experienced tab controllers from an example in a book where the tabbar controller was dragged onto a window in interface builder.
I'd like to try and pin down a direction to set to work to
I would highly recommend re-thinking your use of the tab bar here. The tab bar is intended to be a top-level control for navigating logically separate parts of your applications. Normal use would be tabs that contain navigation controllers that drill into detail within the navigation.
You may consider changing to use a toolbar rather than a tab bar. The toolbar is intended to change for the context of your current view. You can define the toolbar items in the view for the current navigation bar very easily.
All that said, if you are still set on using tab bar, I would keep the tab bar at the top level of your application and use setViewControllers:animated: to change the tabs when necessary. Again, I think this will end up producing a pretty confusing UI however.
