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?

适用于swift4中基于特定视图控制器的导航

   let app = UIApplication.shared
   let statusBarHeight: CGFloat = app.statusBarFrame.size.height

   let statusbarView = UIView(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width, height: statusBarHeight))
   statusbarView.backgroundColor = UIColor.red
   view.addSubview(statusbarView)

通过在viewWillAppear中添加以下内容,我成功地改变了状态栏背景的外观:

let statusBar: UIView = UIApplication.sharedApplication().valueForKey("statusBar") as! UIView

    if statusBar.respondsToSelector(Selector("setBackgroundColor:")) {
        statusBar.backgroundColor = .redColor()
    }

请在“didFinishLaunchingWithOptions launchOptions:”Appdelegate类中使用此代码

UIApplication.shared.statusBarStyle = .lightContent let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as! UIView if statusBar.responds(to: #selector(setter: UIView.backgroundColor)){ statusBar.backgroundColor = UIColor.black }

iOS 13

 var statusBarView: UIView = UIView()
        if #available(iOS 13.0, *) {
            let tag:UInt64 = 38482458385
            if let statusBar = UIApplication.shared.keyWindow?.viewWithTag(Int(tag)) {
                statusBar.backgroundColor = UIColor.red
                statusBarView = statusBar
            } else {
                let statusBar = UIView(frame: UIApplication.shared.statusBarFrame)
                statusBar.tag = Int(tag)
                UIApplication.shared.keyWindow?.addSubview(statusBar)
                statusBarView = statusBar
            }
        } else {
            statusBarView = (UIApplication.shared.value(forKey: "statusBar") as? UIView)!
            if statusBarView.responds(to: #selector(setter: UIView.backgroundColor)){
                statusBarView.backgroundColor = UIColor.red
            }
        }

适用于基于导航的应用

    var addStatusBar = UIView()
    addStatusBar.frame = CGRectMake(0, 0, UIScreen.mainScreen().bounds.width, 20);
    addStatusBar.backgroundColor = global().UIColorFromRGB(0x65b4d9)
    self.window?.rootViewController?.view .addSubview(addStatusBar)

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

在你的AppDelegate文件中的func application方法中

let statusBar: UIView = application.value(forKey: "statusBar") as! UIView
statusBar.backgroundColor = .red
