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 have the first storyboard has UINavigationController its continues to the second storyboard but it doesn't appear there only when running the app.
I link between storyboard by (Storyboard Reference)
The first storyboard
The second storyboard
The UINavigationController doesn't appear in the second storyboard its appear only when running the app.
according to navigation controllers property it will not show the navigation bar in your case , if you want to edit or customise navigation items or navigationbar then you have to make changes programatically .
but to make changes in navigationbar or navigation items there is some limitations sometimes you can't fully customise it and sometimes you customise it depend on your requirement ... :(
I suggest you that use navigation property but hide the navigation bar
and on place of navigation bar (on top of every view controller) set a
view which will look like navigation bar and you can easily customise
it as per your requirement .
This is normal behaviour of the Storyboard as the controller in your second storyboard does not know if it is a controller in a navigation controller, hence it does not show the navigation bar. If yo want to show the navigation bar in the storyboard you can select it in the Simulated Metrics in the Attributes Inspector (shown here in that thread). You can see it working by giving the controller a title for example.
I have UITableViewController embeded in a UINavigationController in my app. When a row is selected it pushes a UITabBarController. So far so good. The problem is that some of the tabs I push more views but the tab bar gets hiden. I've tried setting hidesBottomBarWhenPushed = NO, but it doesn't work.
I'm using XCode 4 with storyboard
Any ideas?
I've had this problem in one of my apps (though it was in iOS 4.x, using nibs not storyboard).
What I did to solve it: You want to have the root controller for each tab (the one with tabitem, etc) be a navigation controller - and when you push new views onto this navstack, they will respect the top navigation bar and bottom tab bar (they may actually display two navbars, so you have to be careful, but generally this is the way to go.)
first of all you might want to take a look at this
viewController: The view controller that is pushed onto the stack. It
cannot be an instance of tab bar controller.
so pushing an instance of tab bar controller is not recommended. There's a good reference there that might accomplish the task you wanted ill just provide the link here
I am working with TabBarController application and my requirement is to add a TabBar at the top of the window rather than default bottom. Can somebody help to add the TabBar at the top of the window while using UITabbarController rather than simple tabbar.
I think that is not permitted when using UITabBarController. From the official docs, about tabBar property:
"You should never attempt to manipulate the UITabBar object itself stored in this property. If you attempt to do so, the tab bar view throws an exception. To configure the items for your tab bar interface, you should instead assign one or more custom view controllers to the viewControllers property. The tab bar collects the needed tab bar items from the view controllers you specify.".
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.
I am trying to make a program with three subviews after the title screen. Two of the views are just standard nib files with UIViewController subclassed to control them, and the third is a Tab Bar view. I can't seem to get the tab bar items to display though. I walked through the Tab bar chapter in "Beginning iPhone Development" which adds the Tab Bar Controller right off the bat as a subview of Window in the app delegate and that works fine. What I want to do though is load up my rootView controller after the third section was chosen from the title screen and then add a Tab Bar view to that. Every time I do this though I get a blank Tab Bar with no tab bar items.
Any help you can provide would be greatly appreciated seeing as I've been working at this for a few days now.
Thanks
You can't push a tab bar controller to a navigation controller, which I assume is what you're trying to do. However, you can use a plain UITabBar and implement your own view switching in a UIViewController subclass (rather than a UITabBarController). See this related question.
