Push / Pop View Controller With Navigation Bar from View Controller Without Navigation Bar

Question

I\'m trying to push a view controller with a visible navigation bar from a view controller with a hidden navigation bar.

I tried all sorts of combinations of

It is possible without hacking together a solution by yourself. Here is what you do:

Your root viewController:

@implementation ViewController

....

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    [self.navigationController setNavigationBarHidden:YES animated:animated];
}

@end

And the pushed viewController:

@implementation SecondViewController

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    [self.navigationController setNavigationBarHidden:NO animated:animated];
}

@end

This will do. It also keeps the interactive transition working ;)

I find it disturbing, however, that this type of functionality is not documented at all by apple. - You can also hide and show toolbars with these 'call-points' (inside viewWillAppear:)

EDIT

I just realized that this is the same code you wrote in your question. Please test it again. I am 100% sure that this works - I used this functionality in one of my apps, too.

Please also note that my code does use animated:animated instead of your animated:NO. This may be the crucial point here :)
