Moving in UINavigationController to controller without NavigationBar

Question

In my iOS app i got two UIViewControllers. I moving from one to another with UINavigationController. But first one with UINavigationBar, when in second i type in viewDidLoad:

self.navigationController.navigationBarHidden = NO;

Then when i open it - on first controller appears big black line on the top. You can see it on image's top left corner:

How should i open it without this black line.

Answer 1

On your first view controllers viewWillAppear method you have to add this line of code

self.navigationController.navigationBarHidden = YES;

Put this code where you don't want to show UINavigationController.

Answer 2

As variant you could add your view on the top in viewDidLoad method of your ViewController:

UIView *magicView = ...;

[self.navigationController.topViewController.view addSubview:magicView];

So in will be above the top of self.view.

But you should change all logic from self.view to magicView (all subviews, all callbacks, etc.)
