这对我来说真是小菜一碟。

去你的应用的info.plist。

“查看基于控制器的状态栏外观”设置为“否” 设置状态栏样式为UIStatusBarStyleLightContent

然后转到你的应用程序的委托，并粘贴下面的代码，你设置你的窗口的RootViewController。

#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))
{
    UIView *view=[[UIView alloc] initWithFrame:CGRectMake(0, 0,320, 20)];
    view.backgroundColor=[UIColor colorWithRed:0/255.0 green:0/255.0 blue:0/255.0 alpha:1.0];
    [self.window.rootViewController.view addSubview:view];
}

宾果。这对我很有用。

简单地调用

[[UINavigationBar appearance] setBarStyle:UIBarStyleBlack];

在

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

我的AppDelegate的方法在iOS7中非常适合我。

只需改变1)信息。plist基于控制器的状态栏外观->否 和写 2）

  [[UIApplication
 sharedApplication]setStatusBarStyle:UIStatusBarStyleLightContent]; 

in

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

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];
    …
}

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

在信息。plist设置字段值NO查看基于控制器的状态栏外观，并在目标>常规设置中设置状态栏样式灯。
