Unable to hide navigation bar in xcode

Question

I have made a simple app using the Storyboard editor in xcode 4.6.3. The first view is a navigation controller with some simple buttons for navigation. This then by default adds the navigation bar to the top of each new view I create when I connect the buttons to each of their pages.

However, I want the first page (landing page I guess I would call it) to have no top bar. I follow the instructions here on how to disable the top navigation bar in Storyboard mode. However, this then disables all navigation bars for all views linked to this main view.

I also change the colour of sub pages' top navigation bars but this does not work either. I run the application on the emulator but the changes dont seem to take affect.

Can anyone please advise? I am new to objective c (experience in Java mostly) and would like to get an app out quickly. My problem is time and Storyboard seems to have solved this as I can get something together fairly quickly.

Answer 1

I just fired up an app and had the same issue, the line you are looking for is:

self.navigationController.navigationBar.hidden = YES;

Full Code is:

- (void)viewWillAppear:(BOOL)animated
{
     self.navigationController.navigationBar.hidden = YES;
}

Make sure you turn it back on with the next controller:

self.navigationController.navigationBar.hidden = NO;

Was only tested in a later version of Xcode but should work fine for 4.6.3

(edit to change from viewDidLoad to viewWillAppear)

Answer 2

in Swift you can use the almost obvious

self.navigationController?.navigationBar.isHidden = true

and

self.navigationController?.navigationBar.isHidden = false

to show or hide the navigation bar. make sure you allow the view to load so call those in viewWillAppear or viewDidAppear.
