Artilheiro   If its a navigationbased project  u can create BaseViewController  All other view will inherit this BaseView  In BaseView u can define generic methods to add right button or to change left button text   ex       interface BaseController   UIViewController            -  void  setBackButtonCaption  NSString   caption        void  setRightButtonCaption  NSString   caption selectot  SEL  selector        end      In BaseView M       void  setBackButtonCaption  NSString   caption       UIBarButtonItem  backButton    UIBarButtonItem alloc  init    backButton title  caption  self navigationItem backBarButtonItem   backButton   backButton release            -  void  setRightButtonCaption  NSString   caption selectot  SEL  selector        UIBarButtonItem  rightButton     UIBarButtonItem alloc  init      rightButton title   caption   rightButton target  self    rightButton setAction selector    self navigationItem rightBarButtonItem  rightButton    rightButton release            And now in any custom view  implement this base view call the methods       interface LoginView   BaseController     In some method call base method as      SEL sel   selector switchToForgotPIN         super setRightButtonCaption   Forgot PIN  selectot sel

Try doing it in viewDidLoad  Generally you should defer anything you can until that point anyway  when a UIViewController is inited it still might be quite a while before it displays  no point in doing work early and tying up memory   -  void viewDidLoad      super viewDidLoad      UIBarButtonItem  anotherButton     UIBarButtonItem alloc  initWithTitle   Show  style UIBarButtonItemStylePlain target self action  selector refreshPropertyList                 self navigationItem rightBarButtonItem   anotherButton       exclude the following in ARC projects       anotherButton release       As to why it isn t working currently  I can t say with 100  certainty without seeing more code  but a lot of stuff happens between init and the view loading  and you may be doing something that causes the navigationItem to reset in between

Try adding the button to the navigationItem of the view controller that is going to be pushed onto this PropertyViewController class you have created   That is   MainViewController  vc     MainViewController alloc  initWithNibName   MainViewController  bundle nil   UIButton  infoButton    UIButton buttonWithType UIButtonTypeInfoLight    infoButton addTarget self action  selector showInfo  forControlEvents UIControlEventTouchUpInside   vc navigationItem rightBarButtonItem      UIBarButtonItem alloc  initWithCustomView infoButton  autorelease    PropertyViewController  navController     PropertyViewController alloc  initWithRootViewController vc     Now  this infoButton that has been created programatically will show up in the navigation bar  The idea is that the navigation controller picks up its display information  title  buttons  etc  from the UIViewController that it is about to display  You don t actually add buttons and such directly to the UINavigationController

This issue can occur if we delete the view controller or try to add new view controller inside the interface builder main storyboard   To fix this issue  it requires to add  Navigation Item  inside new view controller  Sometimes it happens that we create new view controller screen and it does not connect to  Navigation Item  automatically     Go to the main storyboard  Select that new view Controller   Go to the document outline  Check view Controller contents  If new view controller does not have a Navigation item then  copy Navigation item from previous View Controller and paste it into the new view controller  save and clean the project

Why are you subclasses UINavigationController  There is no need to subclass it if all you need to do is add a button to it   Set up a hierarchy with a UINavigationController at the top  and then in your root view controller s viewDidLoad  method  set up the button and attach it to the navigation item by calling    self navigationItem  setRightBarButtonItem myBarButtonItem
