Changing Navigator Buttons depending on displayed views ?

[Thallius]

Hi,

i am new in iOs programming and I've got a small problem at the moment.

I have a Tabbar application. In one Tabbar i have a NavBar and this is connected to a TableView. Everything works fine. Now I've added an "Add" Button in the Navbar and connected it to my TableViewController. When i click on the "Add" Button my function

-(IBAction)addFlight:(id)sender
{
	if(self.addFlightViewController==nil)
	{
		AddFlightViewController *aFlightView=[[AddFlightViewController alloc] initWithNibName:@"AddFlightView" bundle:(NSBundle *)nil];
		self.addFlightViewController=aFlightView;
		[aFlightView release];
	}
	addFlightViewController.title=[NSString stringWithFormat:@"test"];
	
	rcFlightBookAppDelegate *delegate=[[UIApplication sharedApplication] delegate];
	[delegate.flightNavController pushViewController:addFlightViewController animated:YES];
	return;
}

is called and the new view appears. Also the "Back" Button in the Navbar is avaible and works. But i need a "Done" button also, which should be in the right corner of the Navbar.

And here is my problem. I dont know how to add this button ? I think i cant do this in the interface builder, since the button is only visible as long as i am in the AddFlight view? So i must do it programaticly ? If so, what ist the right way ?

Thanks in advance
