ios - Swift 4 中的 statusBarStyle

Question

这是我在 AppDelegate 类(Swift 4)中编写的代码:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
     UIApplication.shared.statusBarStyle = .lightContent
    goToRootViewController()
    UINavigationBar.appearance().isTranslucent = true

    UINavigationBar.appearance().shadowImage = UIImage()
    UINavigationBar.appearance().setBackgroundImage(UIImage(), for: .default)
    GMSServices.provideAPIKey(googleMapApiKey)
    return true
}

但是我的状态栏没有显示浅色内容我不知道发生了什么，有帮助吗？

Answer 1

对于特定的 ViewController 类:

在您的 viewcontroller 类中使用下面的代码 viewDidLoad() :

override var preferredStatusBarStyle : UIStatusBarStyle {
    return .lightContent
}

这将以浅色内容显示您的状态栏

对于整个应用:

在产品的 Info.plist 中设置“View controller-based status bar appearance”键值为“NO”

然后在“didFinishLaunchingWithOptions”内的 AppDelegate.Swift 中使用以下代码:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    
    UIApplication.shared.statusBarStyle = .lightContent
    return true
}
