How to change Title in UIBarButtonItem

Heres how I would do it just to get you started

1. You need to ask the user when they log in (when the app loads) if they want english or spanish you could pop it in the viewDidLoad method as a UI Alert i.e.

UIAlertView * alert =[[UIAlertView alloc ] initWithTitle:@"Welcome to my App" message:@"Choose your language" delegate:self cancelButtonTitle:@"English" otherButtonTitles: nil]; [alert addButtonWithTitle:@"Spanish"]; [alert show];

1. Let them select which ever one they want

2. • (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex

{ if (buttonIndex == 1) {
self.LogOutButton.text=@"English"; //sets it as English

    }

    else{
             self.LogOutButton.text=@"Salida"; //sets it as Spanish

}

Without seeing your code its hard to comment but that above is the line of thinking I would go down to get it working. Also note this is a global approach you could use this to modify the language across the class not just for one button

Thank you Sam for your answer, what I was missing was that I had to make @porperty for uibarbutton that way you can change the title. thank you again.
