How can I add Some Bar Buttons or Segment Controll on my Navigation Controller?

[Kapil Choubisa]

Hi! All.

I an a new in XCode and iphone.
I am facing a problem while trying to add bar button and Segment control to my NavigationController.

I have 4 nib files in my application.
I had added the Navigation controller to my MainWindow.xib file.
Then I had added a Bar button and Segment control on it.
So it is displaying on my first View while I run the application.

But when I move to other views I am not able to see those controls.

I have write one line of code for displaying edit button on navigation control.

self.navigationItem.rightBarButtonItem = self.editButtonItem;
 

is there any code which I have to include in my viewDidLoad event for getting the barButton and Segment Control?

Thank you in Advance.
