my iPhone application consists of a Tab bar controller with several navigation controllers within it, with table views in each of them.
I want it so that after I click on a tab bar item, if I go deeper into the table hierarchy and then click on another tab bar item, if I return back to the tab bar item before, that it goes back to the parent table.
Is there a method to somehow do this?
How about using [navigationController popToRootViewControllerAnimated:NO] when a tab is selected?

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.
I'm trying to add a view that is a form that has 3 elements. These elements will be inside of a static grouped table. I need a navigation bar at the top with a "Save" and "Cancel" button. Both buttons should send the user back to their previous screen when tapped.
Within the storyboard, I have tried creating a Navigation Controller and then adding a table to it, but I get the error of "Static table view are only valid when embedded in UITableViewController".
So, I tried creating a Table View Controller, but the storyboard won't let me put a navigation bar into one of those for some reason...
What is the best way to go about doing this?
Add UITableViewController to your storyboard and then choose Editor > Embed in > Navigation Bar Controller from the menu. This will wrap your table view controller in a nav bar controller and you can then add your Save and Cancel buttons to the navigation bar.
It might seem a bit wasteful to create a navigation controller with only a single sub-controller just to get a navigation bar but it's the accepted way of doing it.
Oh... this iOS stuff is hurting my head.
I wanted to do the same thing, have a TableView, with a Navigation Bar at the top, but there was no "Embed in.. Navigation Bar" menu item, just "Embed in.. Navigation Controller".
Eventually, solving this was easier than I thought.
I just needed to add a Table View Controller to my storyboard, then CTRL+drag a Segue from the "calling" view controller to my new Table View Controller, and, voila, it gives me the Navigation Bar straightaway.
Basic question -
I'm adding a tab bar item to my tabbarcontroller. It's going to be a view.
I feel really dumb for asking this, but…how do you assign the view you want to load for the tab bar item?
"When I click this tab, load this view."
Using Xcode4.
Don't add a tab bar item directly. Instead, drag out a UIViewController from the Library onto the tab bar. This will create a new bar item for you, with a UIViewController. Select the UIViewController itself, and on the Identity tab set the class to your view controller, and on the Attributes tab specify the name of the nib file to load.
Hello everybody i need your help.
I am making a tab bar based application in iphone. i have more than 5 button to show in tab bar. when i did it, five button displayed fifth button is more..... but when i clicked on more then more button came in a table view not in tab bar.
That's how it works. From the documentation (http://developer.apple.com/library/ios/#featuredarticles/ViewControllerPGforiPhoneOS/TabBarControllers/TabBarControllers.html%23//apple_ref/doc/uid/TP40007457-CH102-SW2):
If you add more than five items to the
viewControllers property, the tab bar
controller automatically inserts a
special view controller (called the
More view controller) to handle the
display of the additional items. The
More view controller provides a custom
interface that lists the additional
view controllers in a table, which can
expand to accommodate any number of
view controllers. The More view
controller cannot be customized or
selected and does not appear in any of
the view controller lists managed by
the tab bar controller. For the most
part, it appears automatically when it
is needed and is separate from your
custom content. You can get a
reference to it though by accessing
the moreNavigationController property
of UITabBarController.
That is intended behavior and not an issue, if you read the viewController Programming guide you could have seen that right away: http://developer.apple.com/library/ios/#featuredarticles/ViewControllerPGforiPhoneOS/Introduction/Introduction.html#//apple_ref/doc/uid/TP40007457
I have a tabbar based app and would like to reference one of three views. There are three tabs. When tab2 is clicked, tab2view is created. tab1view needs to reference tab2view so it can be pushed into view. tab2view can be pushed into view via tab2 or tab1view. How do I give tab1view a reference to tab2view?
tab1view will also need to create tab2view if it hasn't already been created from a tab click.
You don't push views with UITabBarControllers, you add View Controllers to an array that get displayed when the user clicks the appropriate tab bar item. If by "push" you mean "switch to tab" then you just need to set the "selectedIndex" property of your TabBarController.
But I don't understand this dependency you have where the second tab's view controller has to be created by the first. If you're not seeing your second tab view when you click on the second tab button, then it means you're doing something wrong in building the tab bar itself.
Regardless, all view controllers in your tab bar are accessible via the "viewControllers" array so getting the second one would be:
UIViewController *secondVC = [[myTabBarController viewControllers] objectAtIndex:1];
