Question

In my appDelegate, under applicationDidFinishLaunching, I have:

[self.navigationController setToolbarHidden:NO];

In a subview, under viewDidLoad I have:

[self.navigationController setToolbarHidden:YES animated:YES];

However, upon hitting back on the navigation controller, the toolbar remains hidden. I’ve tried adding this to the RootViewController with no success. I can’t figure out what’s going wrong.

[self.navigationController setToolbarHidden:NO animated:YES];

In your subview, you can do following:

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

- (void)viewDidDisappear:(BOOL)animated
{
    [self.navigationController setNavigationBarHidden:NO animated:animated];
    [super viewWillDisappear:animated];
}
