override func preferredStatusBarStyle() -> UIStatusBarStyle {
 return UIStatusBarStyle.LightContent;
}

使用上述代码在任何ViewController中为特定的ViewController设置状态栏颜色为白色,在iOS8中对我来说是行不通的。有什么建议吗?使用UIApplication。shared应用方法,在信息中需要更改后颜色更改。Plist为整个应用程序。

// Change the colour of status bar from black to white
UIApplication.sharedApplication().statusBarStyle = .LightContent

我怎么能改变一些必要的和特定的视图控制器的状态栏颜色?

在Swift 5或xcode 11及以后的版本中设置(查看基于控制器的状态栏外观)key In info。plist为NO 然后转到项目目标,选择通用,设置状态栏样式为深色或浅色

对于Xcode 10,你可以创建一个类并把它放在你的viewController类之前,你可以在所有视图控制器中调用这个类,需要一个轻内容状态栏…

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

现在在下面修改你的viewController类:

class YourViewController: UIViewControllerWithLightStatusBar {
...
}

这就是全部……

        setNeedsStatusBarAppearanceUpdate()

        view.backgroundColor = UIColor(red: 61/255, green: 91/255, blue: 151/255, alpha: 1)

    }

    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()
    }

}

自定义状态栏颜色(iOS11+, Swift4+)

如果您正在寻找如何将状态栏更改为自定义颜色的解决方案,这是可行的解决方案。

let statusBarView = UIView()
view.addSubview(statusBarView)
statusBarView.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
    statusBarView.topAnchor.constraint(equalTo: view.topAnchor),
    statusBarView.leftAnchor.constraint(equalTo: view.leftAnchor),
    statusBarView.rightAnchor.constraint(equalTo: view.rightAnchor),
    statusBarView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor)
])
statusBarView.backgroundColor = .blue

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
