Hide/Show Navigation & Tool Bar on tap

This is the void I’m using to hide the Navigation Bar in one of the views.

- (void)viewWillAppear:(BOOL)animated {
    [self.navigationController setNavigationBarHidden:YES];

    [super viewWillAppear:animated];
}

How to tap the screen to hide and show the navigation bar?

Answer 1

Do you wish something like that?

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.navigationController.navigationBar.translucent = YES;
                             self.wantsFullScreenLayout = YES;

    UITapGestureRecognizer *tap = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideShowNavigation)] autorelease];
    tap.numberOfTapsRequired = 1;
    [self.view addGestureRecognizer:tap];
}

- (void) hideShowNavigation
{
    [self.navigationController setNavigationBarHidden:!self.navigationController.navigationBarHidden];
}
