如果你有一个通过Interface Builder创建的嵌入式导航控制器，请确保在管理导航控制器的类中设置以下内容:

-(UIStatusBarStyle)preferredStatusBarStyle{ 
    return UIStatusBarStyleLightContent; 
} 

这应该就是你所需要的。

简单地在应用程序委托:

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

在Swift 5中，遵循以下步骤:

在Info.plist中添加key UIViewControllerBasedStatusBarAppearance并将value设置为false 添加键UIStatusBarStyle和设置值UIStatusBarStyleLightContent

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

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

-[UINavigationBar setBarStyle:UIBarStyleBlack]

在ios7上，如果你想使用UIViewControllerBasedStatusBarAppearance == YES，并且你的根视图控制器是UINavigationController，你应该这样做 子类化它并重载childViewControllerForStatusBarStyle，例如:

- (UIViewController*) childViewControllerForStatusBarStyle
{
    return self.viewControllers.lastObject;
}

在这之后，preferredStatusBarStyle将在被推送的视图控制器上被调用。
