你可以在iOS 6和7中使用这个:

#ifdef __IPHONE_7_0
# define STATUS_STYLE UIStatusBarStyleLightContent
#else
# define STATUS_STYLE UIStatusBarStyleBlackTranslucent
#endif

[[UIApplication sharedApplication] setStatusBarStyle:STATUS_STYLE animated:YES];

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

删除。plist文件中基于视图控制器的状态栏外观(如果你有create)并重新创建它。 设置状态栏样式为不透明黑色样式

在appDelegate中，在didFinishLaunching下添加以下代码。

 [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

这适用于Golden Master iOS7和Xcode 5 GM种子和2013年9月18日发布的iOS7 SDK(至少导航控制器隐藏):

中的UIViewControllerBasedStatusBarAppearance设置为NO Info.plist。 在ViewDidLoad方法或任何地方，你想改变的地方 状态栏样式: [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

在Xcode中最简单的方法(不需要任何编码)是:

添加基于视图控制器的状态栏外观到您的信息。plist，设置为NO。 现在，转到项目目标，在部署信息中，你会发现一个状态栏样式的选项。将此选项的值设置为Light。

你会看到白色状态栏。
