I am using navigation controller for each tab, and the first controller in each tab not showing any item in the navigation, but if I click on cell and return back the items on the navigation shows normally.
Why?
Thanks,

I'm having a requirement where I click a button then I need to initialise the tab and its children, and also I need to push a new page on top of this, which shouldn't show the tabs below, and when I press back it should go back to the previous tabbed page with the children being active from where I navigated from
I know that I can do this by
CurrentPage = Children[2];
This would give me the result of navigating to the specific child of a tabbed page, but how can I navigate to a page further is something I'm not able to figure out
i have a main view with a combo box and its controller, and a second view which gets loaded when a button is clicked on the main view.
the second view contains a button and a label and has its different controller.
what i want to do is, when the button on the second controller is clicked, the selected item on the combo box on the main view should be displayed on the label..
so that when i go back and change the item on the combo box and go back and click the button on the second view ,the text on the label would be changed to the currently selected item.
any help..???
thanks
Apple's documentation on UINavigationItem states the following:
The managing UINavigationController object uses the navigation items
of the topmost two view controllers to populate the navigation bar
with content.
Why the topmost two view controllers instead of just the topmost? Is it just so that when you pop the view controller, it fades one item out and another in?
I think it's because the title of the "Back" button is (by default) the navigation title of the view controller just underneath the top one.
Navigation title: Title of top view controller.
Back Button title: Title of previous view controller.
I have 4 items in my TabBar. One of the items is a "WorkFlowViewController". I want to show "WorkFlowViewController" modally when the user hits that tab in my TabBar, like click on the voicemail tab on Phone App.
How to do that using segue in the storyboard?
I tried to link(Control+mouse) the TabBarViewController with the WorkFlowViewController, Storyboard segue shows four options:
1. relationship
2. push
3. modal
4. custom
if I choose "relationship", it will auto add tab item to the tabbar and works fine(not modally) when the user hits the tab.
if i choose "modal", it won't add the tab item to the tabbar, then the user has no where to click on the tab item. and i can't manually add tab item to my tabbar using storyboard.
Thanks a lot.
You can't. TabBarViewController is a container view controller and thus only option 1 (relationship) is applicable.
I have a navigation controller with a root view controller for which i have the customised titleView instead of normal title for the navigation item.
If i pushed a new controller in it , the default back button title is "back", Since i have used custome titleView.
I want it to be different. I tried by setting the title in backbaritem of the root view controller, but no use.
I can create a bar button item in my pushed controller and i can set it as leftbar item, But i want it like a normal back button. [Pointing towards backward]
Is it possible to set title for the back button , if i have a custom titleView ?
Is it possible to create a bar button item as like as default back button.[Pointing towards back , other than plain,border...etc] ?

I got it.
Even though i have custom titleView for my navigation item, I can still set the title for the same navigation item where it wont be taken for the title display in navigation item . but it will taken as the title of the back button when some other controllers are pushed into it.
So , Now i'm having both title [Used for back title display] and titleView [custom view] in the navigation item.
