Remove navigation bar from main controller in Xcode?

I have a main view controller in Xcode 6 (program in swift), on which I have several buttons that lead to specific navigation controllers. When I test the app, the first time I see it, it looks fine (no navigation bar at the top). When I click on the button on the main view controller, it displays the navigation controller I selected, everything works fine. The problem occurs when I click on the back button on this nav controller to show me my main controller again. When I go back to the main view controller, there will be a navigation bar at the top that shouldn't be there. I want my main view controller to have no navigation bar at the top. I tried using push, modal and show segues to see if this might be the problem,but I still can't figure it out. Any thoughts on what might happen?

It looks like you need to hide the navigation bar again. To do this, add:

self.navigationController?.navigationBarHidden = true

in viewWillAppear

any view controller for which you want to hide the navbar.



Updated for Swift 3:

self.navigationController?.isNavigationBarHidden = true

In mainViewController, write the code to hide the navigation bar in viewWillAppear mode. in Objective-C



-(void)viewWillAppear:(BOOL)animated
{
   [super viewWillAppear:YES];
   [[self navigationController] setNavigationBarHidden:YES animated:NO];
}
