I'm new to iphone development. I'm trying to implement a tab view controller and a navigation controller. The problem that I'm having is that the navigation controller is pushing the tab bar view. How can you make the navigation controller slide without pushing the tab bar view? Any ideas?
You need to post your code, however to achieve the effect you are after you need to create an array of Navigation controllers and add them to your TabBar:
myTabBarController.viewControllers = navigationControllerArray;
When you push a view controller the tabBar will remain in place. Equally if you touch a tab then you will switch to the view controller in the array.
You should not push a tabbar view in navigation controller. Rather you should create a tab bar controller and then add navigation controller to it. Doing so will just slide navigation controller not tab bar. You can refer to iPhone SDK documentation for more information.

when I created the UITableViewController within Modal Screen, I noticed that code refused to show on Navigation Bars with Title in the Modal Screen, but Full Screen has shows it with this code.
self.navigationItem.title = "Tip"
Do someone know any tricks that allow adding that Navigation Bar Title or Navigation Bar needs in Modal Screen supports.
Let me know if you know about this, thank you for helps. :)
If you have a navigation stack with one or more view controllers and one of those view controllers (let's call it A) presents a view controller B modally, B doesn't belong to the navigation stack. It is displayed by A rather than pushed onto the stack by the navigation controller.
If you want to show a navigation bar with your modal view controller, you have 2 options:
1.Add a navigation controller before the view controller you want to present modally:
Navigation Controller 1 -(root 1)-> View Controller A -(modal)-> Navigation Controller 2 -(root 2)-> View Controller B
Or, you can install a navigation bar at the top of the modal view controller.
If you just want a navigation bar for the sake of displaying a title, use option 2, otherwise, if you need a navigation stack, use option 1.
I'm not having any technical troubles but I was wondering if there was a better way to do this in interface builder, considering adding a new nav controller looked repetitive and unnecessary. When I add another view controller to the nav hierarchy (through a Show segue), and then try to add a bar button item, I can't until I embed the view controller in a new nav controller. Here's what I mean:
Unable to add Bar Button Item:
Able to add Bar Button Item:
You don't have to embed each view controller into its own nav controller. For each view controller down the line of one navigation controller, drag a Navigation Item onto the navigation bar. You can then add bar button items and a title.
So I have this application where I have a view controller (which I want to appear first when the app starts) and a tab bar controller. I also have other navigation bar controllers that are in the tab bar controller. I want to place my view controller on top of the tab bar controller. Making the tab bar controller the parent of the view controller would be better though.
But take note, I do not want a tab bar item to represent the view controller and I want the tab bar to appear along with the view controller. I do not and would not want to use storyboards as much as possible. How can i achieve this?
I guess the simplest solution would be to use a screenshot of your tabBar and put it in your HomeViewController as a button. In this case you could use your HomeViewController as rootViewController and in the button action you set the TabBarController as the rootViewController.
Root = Home + Button
-->
Root = TabBar
Perhaps you need four buttons, if you want the correct tab to be selected.
I have a tab bar controller.
From one of the views i want to goto another view via a button, which i have done.
Once on that page i want to go back using the navigation bar.
This is the problem.
How do i get it to go back to the tab bar controller page?
Thanks

You can arrange your view controllers as follows:
Tab bar controller
Navigation Controller
View Controller 1 - button to go View Controller 2 using segue
View Controller 2
So, View Controller 2 will have a back button to go to its previous view controller.
I have a navigation controller and a tab bar where I have buttons for multiple options. When a button is ever pressed it pushes its respective viewcontroller in navigation controller. That's fine, but when I again press the button in tab bar after loading any other suboption viewcontroller in navigation controller, it shows blank screen instead of that "options screen" which it shows when I touch it first time.
I am using this code:
[self.navigationController pushViewController:accountOptions animated:NO];
You're pushing same view controller twice without ever poping it from navigation controller.
You can either pop view controller when switching to another one or push view controllers once on navigation controller in tab bar and be done with it.
