在 Storyboard 中隐藏一个 ViewController 的 NavigationBar

Question

I have found many posts, but still no solution. I am trying to hide a NavigationBar on the initial UIViewController , but i want to still show it on the second UIViewController . Here is my storyboard:

When I turn off the Inferred Top Bar for my Main View Controller, it disappears in Storyboard, but it still shows when I run the app. When I do the same in to the NavigationBar in NavController, it disappears for all three (because they all inherit the no Nav Bar).

I want to show the NavBar in ScrollViewV View Controller, but have it hidden in MainViewController .

All Controllers have the corresponding .h or .m files, but I am confused on how to do this programmatically. Let me know if you need to see anything else. Thank you much!

Answer 1

In your mainViewController, you can do following:

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

---

You might want to show the Navigation bar when hiding this ViewController, for that do the following:

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

Answer 2

如果你想在 Storyboard 中保留东西而不是编辑用户定义的属性并将navigationController.navigationBarHidden设置为一个布尔值检查。

Answer 3

self.navigationController.navigationBarHidden = YES;

Answer 4

I noticed that you also need to add the following to the controller that you do want the navigation to appear.

[self.navigationController setNavigationBarHidden:NO animated:animated];
[super viewWillAppear:animated];

Anyone wanting to know how to do this in Swift?

override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)
    self.navigationController?.navigationBar.hidden = true
}
