在iOS 8中: add NavigationController.NavigationBar.BarStyle = UIBarStyle.Black;对viewDidLoad

在信息。plist设置“视图基于控制器的状态栏外观”为NO

在AppDelegate中添加

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

或者，你可以选择退出基于视图控制器的状态栏外观:

在Info.plist中设置“基于视图控制器的状态栏外观”为“NO”。 调用[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

注意:此方法在iOS9中已弃用。在UIViewController上使用preferredStatusBarStyle代替。(见苹果开发者库)

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

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.

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];
