Hide NavigationBar for one ViewController in Storyboard
提问by Siriss
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:
我找到了很多帖子，但仍然没有解决方案。我试图在初始上隐藏 NavigationBar UIViewController，但我仍想在第二个上显示它UIViewController。这是我的故事板：
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).
当我关闭主视图控制器的推断顶栏时，它会在 Storyboard 中消失，但在我运行应用程序时它仍然显示。当我对 NavController 中的 NavigationBar 执行相同的操作时，它对所有三个都消失了（因为它们都继承了无导航栏）。
I want to show the NavBar in ScrollViewV View Controller, but have it hidden in MainViewController.
我想在 ScrollViewV 视图控制器中显示 NavBar，但将其隐藏在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!
所有控制器都有相应的 .h 或 .m 文件，但我对如何以编程方式执行此操作感到困惑。如果您需要查看其他内容，请告诉我。非常感谢！

In your mainViewController, you can do following:
在您的 mainViewController 中，您可以执行以下操作：
- (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:
您可能希望在隐藏此 ViewController 时显示导航栏，为此请执行以下操作：
- (void)viewDidDisappear: (BOOL)animated
{
[self.navigationController setNavigationBarHidden:NO animated:animated];
[super viewDidDisappear:animated];
}

If you want to keep things in the Storyboard than edit the User Defined Attributes and
set navigationController.navigationBarHiddenas a Boolean checked.
如果你想在故事板中保留东西而不是编辑用户定义的属性并设置navigationController.navigationBarHidden为布尔值检查。

Anyone wanting to know how to do this in Swift?
有人想知道如何在 Swift 中做到这一点吗？
override func viewDidAppear(animated: Bool) {
self.navigationController?.navigationBar.hidden = true
}
回答by whiteagle
self.navigationController.navigationBarHidden = YES;

I noticed that you also need to add the following to the controller that you do want the navigation to appear.
我注意到您还需要将以下内容添加到您希望导航出现的控制器中。
[self.navigationController setNavigationBarHidden:NO animated:animated];
[super viewWillAppear:animated];
