I'm new to iOS development and am working on this app that has a similar interface to the official Twitter app. However, I'm not sure how to organize the view controllers and the hierarchy, especially for UITabBar and UINavigationBar (which one is the parent controller?).
Can you guys point me to the right direction? I started from a blank window-based application project. A list of view controllers in the order of the hierarchy would be really helpful. Thank you.
Make the TabBar Controller your root controller. Then, in every tab where you need navigation, use Navigation Controller. It will add Navigation Bars, which you can then modify either in IB (where it applies), or programmatically.

I have created an application successfully and given it a TabBar view controller that is working as i had hoped, but have run into a glitch.
On each xib i load from the tabBar I need to create sub-views that will perform tasks as this interacts with a database (or .. will). I have created my first page and the buttons that will navigate to the views within the XIB, but do not yet nkow how to navigate between views within the XIB itself.
would it be better to have seperate XIB's that load when the buttons are hit?
OR
should i create views within the XIB's for each category and switch between them?
I am still learning and have had some confusion regarding navigation as I already have the TabBar controlling the root of the application. I have been looking for tutorials, but they all seem to start at either navigation controller as the root, TabBar as the root, and nothing like I need for option 1 above.
I can add details of the app if needed, but am looking for guidance for now.
Thank you,

To navigate between views the best way is to use a navigation controller pushing/popping separate view controllers, loaded from separate nibs. UINavigationController is a subclass of UIViewController, so you can perfectly put a navigation controller for each tab. You can also use story-boarding in the new xcode 4.2, but I recommend getting comfortable with this before doing so.
Basically I have an app that involves a navigation controller that moves between table views and scroll views. I wish to place iAds under the navigation bar but before the content of the page.
I assumed that in the mainwindow_iphone.xib I could just move down the view down from the navigation bar and have the app delegate handle the ads but apparently you cannot separate the navigational bar like this.
How would I go about implementing this? I would prefer to avoid having a separate banner load on each page.
If anyone needs anymore information from me, feel free to ask!
Thank you.
I am building a view based application in xcode, and i am new to all the coding and stuff doing it now for 2 weeks. everything went great until i wanted to add a tab bar to by project.
I have searched the interwebz for this for a long time, but all that i could find was people explaining how you can add a tabbar to a window based application, Or how to build a tab bar with a tab bar application. Can someone please help me.
And there is one more thing, i don't want to add the tabbar to the first view. I have an application with some buttons, who take you to different views, and i want to add the tabbar to the fift view, so i can not build it in the app delegate i think.
I hope this explains my problem and i sure hope someone could help me.
thanks.
Start with a UITabBarController.
WHen you use it in Interface builder you can add UITabBarItems (the items to select).
You can link each TabBarItem to a certain NIB. Make your NIBs for every view you want to show. Set every TabBarItem class to the correct controller of your NIB files, these will be used as the file owner of that NIB.
So:
-Make a Main NIB
-Make NIBs for every controller and make the views.
-Make the controllers and link the controllers to the NIB.
-Implement the code.
Switching UITabBarItems will make automatically change the Controllers.
Here is a tutorial for this implementation: Tutorial
I have an app where the appDelegate has a UITabBarController. Each of the tabs has a navigation controller which I currently use to push a single detail view onto the stack in each tab. I am hoping to replace my navigation controller on each of the tabs with a splitViewController. I use the Interface builder to provide the UINavigationController for each tab. I am having trouble loading a nib for each tab that has a UISplitViewController in it. I am getting an instance of the UITableViewController class displaying on the screen, but I am not getting the UISplitviewController or the Popover or the detail view etc. These classes are all working in a standalone app, but I am not able to get them into each of the tabs in one app. Although I am currently using the Interface Builder I am open to doing this programmatically. If someone has suggestions, or an example small project of a Tab based app with individual split views in the tabs I would appreciate it very much. (As this is my first question I am not sure how much code or other pictures from IB would be helpful for me to post. If you need further detail please let me know and I would gladly amend this post.)
Apple documentation
"The split view controller’s view should always be installed as the root view of your application window. You should never present a split view inside of a navigation or tab bar interface."
Moving on...
Not only shouldn't you -- if you do so, an error is thrown when you run. It's impossible.
I'm developing an iPhone application and I'm trying to do this:
I want an application with tree views. The view shown first, doesn't have a navigation bar. If the user tap on a button, I need to open the second view with a navigation bar and a table view. The user can also add new items to the table view. If the user do so, the application will show the third view where the user can add fields (this view has also a navigation bar).
It may seem simple, but for me it is not. I don't know how to use the UINavigationController and have not found yet a similar example for what I do (paragraph translated by google).
UPDATE
I don't know how where to put UINavigationController.
How can I do that? Can I use a UIViewController to call a UINavigationController?
Thank you.
take a look at the Recipes example (it also uses core data which may confuse things a little) http://developer.apple.com/iphone/library/samplecode/iPhoneCoreDataRecipes/Introduction/Intro.html#//apple_ref/doc/uid/DTS40008913
There is also a simpler starting point here http://developer.apple.com/iphone/library/samplecode/TableViewSuite/Introduction/Intro.html#//apple_ref/doc/uid/DTS40007318 but the Recipe example covers just about everything you need.
EDIT:added the following
For the very simplest example use XCode to build a new application - a navigation based application (sorry, I'm in front of a PC today so that is from memory). That will give you a blank application with the navigation controller created. You then use the navigation controller to push and pop your view controllers
