对我来说，什么都没用。我试图改变状态栏颜色在ViewController2，这是嵌入在NavigationController，这反过来，从ViewController1被模态地呈现。这种方法行不通:

override var preferredStatusBarStyle: UIStatusBarStyle {
    return .darkContent
}

什么都没有发生，直到我找到了这个解决方案: 将这一行添加到ViewController1

导航控制器。modalPresentationCapturesStatusBarAppearance = 真正的

let navigationController = UINavigationController(rootViewController: viewController2)
navigationController.modalPresentationStyle = .overFullScreen
navigationController.modalTransitionStyle = .crossDissolve           
navigationController.modalPresentationCapturesStatusBarAppearance = true
self.present(navigationController, animated: true)

所以如果你的导航方案类似于ViewController1呈现的ViewController2，尝试modalPresentationCapturesStatusBarAppearance属性呈现的一个

文档:

The default value of this property is false. When you present a view controller by calling the present(_:animated:completion:) method, status bar appearance control is transferred from the presenting to the presented view controller only if the presented controller's modalPresentationStyle value is UIModalPresentationStyle.fullScreen. By setting this property to true, you specify the presented view controller controls status bar appearance, even though presented non-fullscreen. The system ignores this property’s value for a view controller presented fullscreen.

这里有一个更好的解决方案 扩展导航控制器并放入故事板

class NVC: UINavigationController {

    override var preferredStatusBarStyle: UIStatusBarStyle {
              return .lightContent
    }

    override func viewDidLoad() {
        super.viewDidLoad()

    self.navigationBar.isHidden = true
    self.navigationController?.navigationBar.isTranslucent = false
      
     self.navigationBar.barTintColor = UIColor.white
     setStatusBarColor(view : self.view)
    }
    

    func setStatusBarColor(view : UIView){
             if #available(iOS 13.0, *) {
                 let app = UIApplication.shared
                 let statusBarHeight: CGFloat = app.statusBarFrame.size.height
                 
                 let statusbarView = UIView()
              statusbarView.backgroundColor = UIColor.black
                 view.addSubview(statusbarView)
               
                 statusbarView.translatesAutoresizingMaskIntoConstraints = false
                 statusbarView.heightAnchor
                     .constraint(equalToConstant: statusBarHeight).isActive = true
                 statusbarView.widthAnchor
                     .constraint(equalTo: view.widthAnchor, multiplier: 1.0).isActive = true
                 statusbarView.topAnchor
                     .constraint(equalTo: view.topAnchor).isActive = true
                 statusbarView.centerXAnchor
                     .constraint(equalTo: view.centerXAnchor).isActive = true
               
             } else {
                 let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView
              statusBar?.backgroundColor = UIColor.black
             }
         }
}

状态栏颜色将为黑色，文本将为白色

在Swift 3非常简单，只需2步。 去你的信息。将基于视图控制器的状态栏外观更改为“NO”。 然后在Appdelegate中在didfinishlaunchingwithoptions方法中添加这一行

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

这在iOS9中已经被弃用，现在你应该在rootviewcontroller中重写这个属性

这样做在iOS 9中已经被弃用，应该在rootviewcontroller上这样做

override var preferredStatusBarStyle: UIStatusBarStyle {
        return .lightContent
 }

实现这一功能的关键是只有全屏视图控制器才能指定状态栏的样式。

如果你正在使用一个导航控制器，并且想要在每个视图控制器的基础上控制状态栏，你会想要子类化UINavigationController并实现preferredStatusBarStyle，这样它就会返回topViewController的首选项。

确保你将故事板场景中的类引用从muinavigationcontroller更改为你的子类(例如下面例子中的MyNavigationController)。

(以下方法对我有用。如果你的应用程序是基于TabBar，你会想做类似的事情通过子类化UITabBarController，但我还没有尝试出来)。

@interface MyNavigationController : UINavigationController

@end

@implementation MyNavigationController

- (UIStatusBarStyle)preferredStatusBarStyle
{
    return self.topViewController.preferredStatusBarStyle;
}

@end

extension UIApplication {

    var statusBarView: UIView? {
        return value(forKey: "statusBar") as? UIView
    }
}

如果你想用Swift得到同样的结果，你可以在你的AppDelegate.swift文件中使用下面的代码:

UINavigationBar.appearance().barStyle = .BlackTranslucent

你的状态栏的文本将是白色的:-)!
