ios - 如何在 iOS13 上设置导航 Controller 中嵌入的状态栏的样式？

Question

许多 iOS 开发者都面临着 iOS 13 更新的一些问题。其中之一就是状态栏样式的不同管理

在 iOS 12 上我曾经这样设置导航栏样式

self.navigationController?.navigationBar.barStyle = .black

影响状态栏样式，设置为白色(因为导航栏样式为黑色)；但它似乎在 iOS 13 上不起作用，我想它需要处理一些事情

UINavigationBarAppearance() 

类

我像这样为每个 ViewController 配置了我的导航栏:

if #available(iOS 13.0, *) {
            let navBarAppearance = UINavigationBarAppearance()
            navBarAppearance.configureWithOpaqueBackground()
            navBarAppearance.accessibilityTextualContext = .sourceCode
            navBarAppearance.titleTextAttributes = [.foregroundColor: UIColor.white]
            navBarAppearance.largeTitleTextAttributes = [.foregroundColor: UIColor.white]
            navBarAppearance.backgroundColor = .brownCircles
            navBarAppearance.shadowImage = nil // remove navigationBar Bottom border
            navBarAppearance.shadowColor = nil // remove navigationBar Bottom border

            self.navigationController?.navigationBar.standardAppearance = navBarAppearance
            self.navigationController?.navigationBar.compactAppearance = navBarAppearance
            self.navigationController?.navigationBar.scrollEdgeAppearance = navBarAppearance

        } else {
            self.navigationController?.navigationBar.barTintColor = .blue
            self.navigationItem.title = NSLocalizedString(kTitle, comment: kTitle.capitalized)
        }
self.navigationController?.navigationBar.barStyle = .black

到目前为止还不错，但是

self.navigationController?.navigationBar.barStyle = .black

仅适用于 iOS 12，在 iOS 13 上没有任何反应，状态栏看起来仍然是黑色而不是白色

有人遇到过这个问题吗？

Answer 1

我终于明白了!

设置亮状态栏文本的魔法代码是:

 self.navigationController?.navigationBar.overrideUserInterfaceStyle = .dark

当然，如果您想更改为深色文本，我必须将其设置为.light。

一些注意事项:

• 这段代码:

  if #available(iOS 13.0, *) {
      overrideUserInterfaceStyle = .dark
  }
  

  虽然它应该将整个 View 和 subview 设置为深色，但似乎不会影响状态栏。

• 您还可以使用:

  UIApplication.shared.statusBarStyle = UIStatusBarStyle.lightContent

  但当然已被弃用，所以我会推荐其他方式

• 你还需要:

  self.navigationController?.navigationBar.barStyle = .black,但将它放在 之后 UINavigationBarAppearance() 设置和 self.navigationController?.navigationBar.overrideUserInterfaceStyle = .dark 之后。

最终代码如下所示:

if #available(iOS 13.0, *) {
        let navBarAppearance = UINavigationBarAppearance()
        navBarAppearance.configureWithOpaqueBackground()
        navBarAppearance.accessibilityTextualContext = .sourceCode
        navBarAppearance.titleTextAttributes = [.foregroundColor: UIColor.white]
        navBarAppearance.largeTitleTextAttributes = [.foregroundColor: UIColor.white]
        navBarAppearance.backgroundColor = .brownCircles
        navBarAppearance.shadowImage = nil // remove navigationBar Bottom border
        navBarAppearance.shadowColor = nil // remove navigationBar Bottom border

        self.navigationController?.navigationBar.standardAppearance = navBarAppearance
        self.navigationController?.navigationBar.compactAppearance = navBarAppearance
        self.navigationController?.navigationBar.scrollEdgeAppearance = navBarAppearance

        self.navigationController?.navigationBar.overrideUserInterfaceStyle = .dark
} else {
        self.navigationController?.navigationBar.barTintColor = .blue
        self.navigationItem.title = NSLocalizedString(kTitle, comment: kTitle.capitalized)
}
self.navigationController?.navigationBar.barStyle = .black
