extension UIApplication {

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

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.

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];
    …
}

总结一下，编辑你的项目信息。Plist并添加:

基于视图控制器的状态栏外观:NO

状态栏样式:不透明的黑色样式

或者如果你有raw key/value plist

uiviewcontrollerbasedstatusbar外观:NO

UIStatusBarStyle:不透明黑色风格

在Plist中添加以下内容:

状态栏样式:UIStatusBarStyleLightContent 基于视图控制器的状态栏外观:NO

您不需要编写任何代码就可以做到这一点! 做以下使状态栏文本颜色白色通过整个应用程序

在你的项目plist文件中:

状态栏样式:透明黑色样式(alpha值为0.5) 基于视图控制器的状态栏外观:NO 状态栏初始隐藏:NO
