如何在 iOS 中更改状态栏文本颜色

How to change Status Bar text color in iOS

提问by Oleksandr Veremchuk

My application has a dark background, but in iOS 7 the status bar became transparent. So I can't see anything there, only the green battery indicator in the corner. How can I change the status bar text color to white like it is on the home screen?

我的应用程序有一个黑暗的背景，但在 iOS 7 状态栏变得透明。所以我在那里什么也看不到，只有角落里的绿色电池指示灯。如何像在主屏幕上一样将状态栏文本颜色更改为白色？

1. Set the UIViewControllerBasedStatusBarAppearanceto YESin the .plist file.

2. In the viewDidLoaddo a [self setNeedsStatusBarAppearanceUpdate];

3. Add the following method:

   - (UIStatusBarStyle)preferredStatusBarStyle
   { 
       return UIStatusBarStyleLightContent; 
   }
   

1. 在 .plist 文件中设置UIViewControllerBasedStatusBarAppearanceto YES。

2. 在viewDidLoad做一个[self setNeedsStatusBarAppearanceUpdate];

3. 添加以下方法：

   - (UIStatusBarStyle)preferredStatusBarStyle
   { 
       return UIStatusBarStyleLightContent; 
   }
   

Note: This does not work for controllers inside UINavigationController, please see Tyson's comment below:)

注意：这不适用于内部控制器UINavigationController，请参阅下面泰森的评论:)

Swift 3- This will work controllers inside UINavigationController. Add this code inside your controller.

Swift 3- 这将在UINavigationController. 将此代码添加到您的控制器中。

// Preferred status bar style lightContent to use on dark background.
// Swift 3
override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
}

Swift 5 and SwiftUI

Swift 5 和 SwiftUI

For SwiftUI create a new swift file called HostingController.swift

对于 SwiftUI，创建一个名为的新 swift 文件 HostingController.swift

import Foundation
import UIKit
import SwiftUI

class HostingController: UIHostingController<ContentView> {
    override var preferredStatusBarStyle: UIStatusBarStyle {
        return .lightContent
    }
}

Then change the following lines of code in the SceneDelegate.swift

然后更改以下代码行 SceneDelegate.swift

window.rootViewController = UIHostingController(rootView: ContentView())

to

到

window.rootViewController = HostingController(rootView: ContentView())

Alternatively, you can opt out of the view-controller based status bar appearance:

或者，您可以选择退出基于视图控制器的状态栏外观：

1. Set View controller-based status bar appearanceto NOin your Info.plist.
2. Call [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

1. 设置View controller-based status bar appearance到NO你Info.plist。
2. 称呼 [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

Note: This method has been deprecated in iOS9. Use preferredStatusBarStyleon the UIViewController instead. (see Apple Developer Library)

注意：此方法在 iOS9 中已被弃用。preferredStatusBarStyle改为在 UIViewController 上使用。（请参阅Apple 开发人员库）

For me, nothing happened with using all the things in the other answers (and from other sources/documentation). What did help was to set the Navigation Bar Style to "Black" in the XIB. This changed the text to white without any code at all.

对我来说，使用其他答案（以及其他来源/文档）中的所有内容都没有发生任何事情。有帮助的是在 XIB 中将导航栏样式设置为“黑色”。这将文本更改为白色，根本没有任何代码。

None of that worked for me, so here is a working solution...

这些都不适合我，所以这里有一个可行的解决方案......

In Info.plist, add a row:

在 中Info.plist，添加一行：

UIViewControllerBasedStatusBarAppearance, and set the value NO.

UIViewControllerBasedStatusBarAppearance，并设置值NO。

Then in AppDelegate in didFinishLaunchingWithOptions, add these rows:

然后在 AppDelegate 中didFinishLaunchingWithOptions，添加以下行：

[application setStatusBarHidden:NO];
[application setStatusBarStyle:UIStatusBarStyleLightContent];

You dont need to do any code for this

你不需要为此做任何代码

You need to add "View controller-based status bar appearance" key in info.plist as follows:

您需要在 info.plist 中添加“基于视图控制器的状态栏外观”键，如下所示：

& set its value type to Boolean & value to NO. Then click on project settings,then click on General Tab & under Deployment Info set the preferred status bar style to .Light as follows:

& 将其值类型设置为布尔值 & 值设置为 NO。然后单击项目设置，然后单击常规选项卡 & 在部署信息下将首选状态栏样式设置为 .Light，如下所示：

Thats it.

就是这样。

这适用于 2013 年 9 月 18 日发布的 Golden Master iOS 7 和 Xcode 5 GM 种子和 iOS7 SDK（至少隐藏了导航控制器）：

In case your UIViewController is inside a UINavigationController you will have to set the BarStyle:

如果您的 UIViewController 在 UINavigationController 内，您将必须设置 BarStyle：

-[UINavigationBar setBarStyle:UIBarStyleBlack]
