如何在第一个ViewController或swift中的特定ViewController中隐藏导航栏？

我在viewDidLoad()中使用了以下代码：

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationController?.isNavigationBarHidden = true
}

以及viewWillAppear：

override func viewWillAppear(animated: Bool) {
    self.navigationController?.isNavigationBarHidden = true
}

两种方法都隐藏了所有ViewControllers的导航控制器。

Answer 1

Swift 3

isInLobby

Answer 2

如果您知道所有其他视图都应该显示该栏，则可以使用viewWillDisappear将其设置为再次显示。

在斯威夫特：

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    navigationController?.setNavigationBarHidden(true, animated: animated)
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    navigationController?.setNavigationBarHidden(false, animated: animated)
}

Answer 3

您可以在navigationController

中取消隐藏viewWillDisappear

override func viewWillDisappear(animated: Bool)
{
    super.viewWillDisappear(animated)
    self.navigationController?.isNavigationBarHidden = false
}

Swift 3

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)

    self.navigationController?.setNavigationBarHidden(false, animated: animated)
}

Answer 4

您还可以为此创建扩展，这样您就可以重复使用扩展，而无需在每个视图控制器中反复执行此操作。

import UIKit

extension UIViewController {
    func hideNavigationBar(){
        // Hide the navigation bar on the this view controller
        self.navigationController?.setNavigationBarHidden(true, animated: true)

    }

    func showNavigationBar() {
        // Show the navigation bar on other view controllers
        self.navigationController?.setNavigationBarHidden(false, animated: true)
    }

}

所以你可以使用下面的扩展方法

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        hideNavigationBar()
    }

    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        showNavigationBar()
    }

Answer 5

在Swift 3中，你也可以使用isNavigationBarHidden属性来显示或隐藏导航栏

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    // Hide the navigation bar for current view controller
    self.navigationController?.isNavigationBarHidden = true;
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    // Show the navigation bar on other view controllers
   self.navigationController?.isNavigationBarHidden = false;
}

Answer 8

您可以从窗口控制器（Swift3）

执行此操作

class WindowController: NSWindowController {

    override func windowDidLoad() {
        super.windowDidLoad()

        window?.titleVisibility = .hidden
    }
}

Answer 9

在IOS 8中，这样做

navigationController?.hidesBarsOnTap = true

但仅当它是 UINavigationController

的一部分时当你想要它时，

将它弄错

Answer 10

我使用上面的变体，并将我的应用程序的各个部分隔离在不同的NavControllers中。这样，我不必重置可见性。例如，在启动序列中非常有用。

Answer 11

 private func setupView() {
        view.backgroundColor = .white
        navigationController?.setNavigationBarHidden(true, animated: false)
    }

Answer 12

在视图中调用set hide方法将显示和消失。如果您不调用视图中的方法，它将消失，状态为false。它将在完整的导航层次结构中隐藏导航栏

Answer 13

    /*.  Swift 5  */     
    let controller =  self.storyboard?.instantiateViewController(withIdentifier: "sc_userNavigation") as! UserNavigationViewController
    let navigationController = UINavigationController(rootViewController: controller)
    navigationController.setNavigationBarHidden(true, animated: false)
    navigationController.modalPresentationStyle = .fullScreen
    self.present(navigationController, animated: false, completion: nil)
