对于swift 3

.plist

View controller-based status bar appearance = NO

AppDelegate.swift

  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Custom statubar
        UIApplication.shared.isStatusBarHidden = false
        UIApplication.shared.statusBarStyle = .lightContent
        let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as! UIView
        statusBar.backgroundColor = UIColor.gray

        return true
    }

斯威夫特4.2 嘿，我想分享一个解决方案，我从格雷格·格鲁米特的一篇关于这个神秘主题的好文章中得到的。

步骤1 正如其他人所提到的，添加到你的PLIST

View controller-based status bar appearance YES

步骤2在RootViewcontroller中添加如下

var statusBarHidden: Bool = false {
        didSet(newValue) {
            UIView.animate(withDuration: 0.1) {
                self.setNeedsStatusBarAppearanceUpdate()
            }
        }
    }

    override var prefersStatusBarHidden: Bool {
        return statusBarHidden
    }

    var vcStatusBarStyle: UIStatusBarStyle = .default {
        didSet(newValue) {
            UIView.animate(withDuration: 0.1) {
                self.setNeedsStatusBarAppearanceUpdate()
            }
        }
    }

    override var preferredStatusBarStyle: UIStatusBarStyle {
        return vcStatusbarStyle
    }

当更新属性statusBarHidden或vcStatusBarStyle时，它将调用setNeedsStatusBarAppearanceUpdate()，并将更新状态栏与prefersStatusBarHidden或preferredStatusBarStyle的新值。在我的情况下，我必须为容器视图控制器更新这些属性，这是可见的子视图控制器的父。我使用一个简单的委托方法做到了这一点。

protocol MainViewControllerDelegate {
    func updateStatusBarStyle(statBarStayle: UIStatusBarStyle)
    func toggleStatusBar(visable: Bool)
}

当然，当实例化childViewController(Visible VC)时，不要忘记将MainViewcontroller(Container VC)设置为它的委托。我有时会。：）

childViewController.delegate = self

然后在childViewController中，当需要更新状态栏时，我只调用委托方法。

self.delegate?.updateStatusBarStyle(statBarStayle: .default)

如上所述，Graig Grummitt详细介绍了这个解决方案，也与UINavigationControllers一起工作。链接这里:状态栏的神秘案例

我在这个问题上遇到了一些麻烦。我不太喜欢在视图中全局改变状态栏的颜色，然后在视图中改变它，然后像接受的答案一样消失。信不信由你，你可以通过在你想要的视图控制器上重写preferredStatusBarStyle来实现。经过很长一段时间，这是我所做的让它工作:

Change View controller-based status bar appearance in your info.plist to YES. Now any full screen view controller can change the status bar style by overriding preferredStatusBarStyle. I specify full screen because this will not work for (non-full screen) modal view controllers, not without setting modal​Presentation​Captures​Status​Bar​Appearance to Yes that is. Also if you have embedded view controllers, like in a navigation controller for example, it will ask the top most view controller for status bar style. Overriding child​View​Controller​For​Status​Bar​Style and passing the embedded view controller is supposed to work but it didn't for me. So I just returned the embedded view controllers preferred status bar as the preferred status bar style. Something like this: override var preferredStatusBarStyle: UIStatusBarStyle { if let topViewController = viewControllers.last { return topViewController.preferredStatusBarStyle } return .default }

我已经设置了特定的颜色(在RGB格式)使用下面的代码在应用程序委托文件:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
. . .

 UIApplication.sharedApplication().statusBarHidden = false
        UIApplication.sharedApplication().statusBarStyle = .LightContent

        let statusBar: UIView = UIApplication.sharedApplication().valueForKey("statusBar") as! UIView
        if statusBar.respondsToSelector(Selector("setBackgroundColor:")) {
            statusBar.backgroundColor = UIColor.init(red: 0.1, green: 0.27, blue: 0.60, alpha: 1.0)
        }

. . .
}

您还需要添加以下关键信息。Plist文件:

查看基于控制器的状态栏外观，布尔值设置为NO

(截至2020年6月10日)

Swift 5(不编辑。plist文件)

如果你正在使用故事板，转到导航控制器，选择导航栏，单击属性检查器，然后更改样式。如果你需要浅色内容(白色状态栏)，设置它除了默认设置样式黑色，如果你想要深色内容(黑色状态栏)，设置它默认。

默认的(UIBarStyleDefault)导致前景UIStatusBarStyleDefault状态栏为黑色。UIBarStyleBlack会给出一个uistatusbarstyelightcontent状态栏。

编程

let nav = UINavigationController(rootViewController: rootViewController)

    nav.navigationBar.barStyle = .default //gives you dark Content status bar

    nav.navigationBar.barStyle = .black  //gives you light content status bar

没有导航栏(编辑。plist)

添加UIViewControllerBasedStatusBarAppearance /基于视图控制器的状态栏外观到你的信息。Plist, set value为true。

重写控制器中的preferredStatusBarStyle属性

class ViewController: UIViewController {
    override var preferredStatusBarStyle : UIStatusBarStyle {
        return .lightContent
    }
}

override func viewWillAppear(animated: Bool) {
    self.navigationController?.navigationBarHidden =  true

    UIApplication.sharedApplication().statusBarHidden = false
    UIApplication.sharedApplication().statusBarStyle = .LightContent

    let statusBar: UIView = UIApplication.sharedApplication().valueForKey("statusBar") as! UIView
    if statusBar.respondsToSelector("setBackgroundColor:") {
        statusBar.backgroundColor = UIColor.redColor()
    }

}
