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
 }

如果你的UIViewController在UINavigationController中，你必须设置BarStyle:

-[UINavigationBar setBarStyle:UIBarStyleBlack]

原始答案在这里

在AppDelegate。M，添加以下内容。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

} 

在Plist文件中，将“基于视图控制器的状态栏外观”设置为NO。

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

这招对我很管用:

在plist中设置UIViewControllerBasedStatusBarAppearance为YES rootViewController需要方法实现 ——(UIStatusBarStyle) preferredStatusBarStyle

因为我的rootViewController是由Cocoapods (JASidePanelController)管理的，我通过一个类别添加了这个方法:

#import "JASidePanelController+StatusBarStyle.h"

@implementation JASidePanelController (StatusBarStyle)

- (UIStatusBarStyle)preferredStatusBarStyle
{
    return UIStatusBarStyleLightContent;
}

@end

只需以下两步:

步骤1:

在项目目标的Info选项卡下，添加行:

UIViewControllerBasedStatusBarAppearance，设置值NO。

步骤2:

在项目AppDelegate.m中:

- (BOOL)application:(UIApplication *)application 
        didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
    …
    [application setStatusBarStyle:UIStatusBarStyleLightContent];
    …
}
