Wonder if anyone can help me with this problem. I have created a Window based application. I have then added a Navigation Controller to the Window (via Interface builder) and subclassesd UITableViewController and used the table delegates in this class to draw my root view table. This all works fine.
I am now trying to add a tab bar to the view. I have done this by dragging a UITabbar in Interface Builder onto the Main Window.
The problem is that when I launch the app, it looks like the table is now being drawn over the top of the UITabbar which therefore makes the UITabbar unaccessible.
Can anyone help me ?
Thanks in advance,
Martin
Have a look at View Controller Programming Guide for iOS : Tab Bar Controllers
If you want to add a tab bar to your application, it should be the main navigation base of your application. Navigation Controller can be part of each tab.
Create a tabBarController. Create navigation Controllers with appropriate View Controllers as its Root View Controller, add the Navigation Controllers into one array, set it to the viewControllers aray of tabBarController object and add the tabBarController.view to your window.
Have a look at this thread, both coding & IB approach has been explained here.
The better and easier approach would be to create UITabbar based application with navigation and add UITableView into that.

Hi I'm new IOS and have been using the storyboard feature, I followed this tutorial which resulted in a working app. I'm slightly confused when to use a navigation controller. In the tutorial above, every tab had a navigation controller. Is this necessary?
I'm in the process of creating a new app and it seems to work whether I add a navigation controller or not to each tab (see pic).
I'm just curios what is the correct process?
Thanks.
As your app is using a UITabBarController each tab will display a separate 'branch' of views. If any of these 'branches' needs its views to be wrapped in navigation functionality (or simply display the navigation bar with a title etc) then you would add a 'UINavigationController` as the primary view controller for that tab, in between the tab bar controller and the first view controller you wish to display for that tab.
If you want a tab to simply display a view controller which doesn't need hierarchical navigation or a navigation bar then you wouldn't need to use a UINavigationController and can directly set your view controller as the controller for that tab.
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 relatively new to programming for the iphone OS, but know the basics and some other things. What I am wondering is how would I program an app that acts like there is a navigation controller, just without the navigation controller bar that comes with it?
Try a UITabBarController : UITabBarController Class Reference.
You can hide the navigationBar that comes with the controller and maintain all the functionality that the navigationController provides. Pass the following method to the navigationController to hide/show the bar.
- (void)setNavigationBarHidden:(BOOL)hidden animated:(BOOL)animated
Another alternative is to have a main view that you swap out subviews from, using an animation as you add or remove views...
But using a navigation controller with the navigation bar hidden as Daniel noted is much simpler.
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.
I have setup a tab bar application with four tabs on the bottom (as set inside IB) Three of them are UIViews and one of them is a UITableView, and the empty shell of an app switches between tabs fine.
Now, being that I have no experience with tab bars, I am not sure where my logic for the view controllers goes. I am used to setting up a ViewController for each view, is that the case in a tab bar? Does each tab need a separately programmed viewcontroller? If not, how can I link my logic to the correct tab's view?
Please help. Thanks!
A UITabBarController manages an array of UIViewController objects. These in turn manage the UIViews that are visible to the user.
So yes, you need to create a separate UIViewController for each view that you want the UITabBarController to manage.
