UINavigationBar 在 scroll/swipe 上隐藏后不会再次显示

Question

正如标题所说，navigationBar在滚动后隐藏不显示。我尝试在 xCode 中以及以编程方式设置它。无论哪种方式，问题仍然存在。

override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)

        navigationController?.hidesBarsOnSwipe = true
    }

这是隐藏导航栏后的样子。请注意，状态栏颜色也从白色变为黑色。

在 viewDidLoad 中我有：

 //MARK: navigation bar styles
        self.navigationController?.navigationBar.backgroundColor = UIColor.init(red: 26/255, green: 24/255, blue: 24/255, alpha: 1)
        self.navigationController?.navigationBar.clipsToBounds = true
        self.navigationController?.navigationBar.titleTextAttributes =  [NSFontAttributeName:UIFont(name:"GillSans", size: 20)!]

有没有人对此有好的解决方案？预先感谢您的帮助！

Answer 1

试试这个代码：

注意： 当您将导航栏背景设置为接近黑色时。您必须将状态栏内容更改为浅色。

//用下面的代码更新你的plist

 View controller-based status bar appearance = NO

在你的ViewController中：

    title = "Some Title"

    navigationController?.navigationBar.barTintColor = UIColor(red: 26/255, green: 24/255, blue: 24/255, alpha: 1)
    navigationController?.navigationBar.tintColor = UIColor.white

    //Title Colour and Font
    navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName:UIColor.white, NSFontAttributeName:UIFont(name:"Arial", size: 20)!]

    navigationController?.navigationBar.clipsToBounds = false
    UIApplication.shared.statusBarStyle = .lightContent
   }


   override func viewDidAppear(_ animated: Bool) {

    navigationController?.hidesBarsOnSwipe = true

    }

输出：

UINavigationBar 在 scroll/swipe 上隐藏后不会再次显示

UINavigationBar won't show again after hiding on scroll/swipe
