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?

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
    }

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)

如果有人想改变状态栏的电池和文本颜色,如下图所示:

您可以在appdelegate类中使用以下代码。

UINavigationBar.appearance().barTintColor = UIColor(red: 234.0/255.0, green: 46.0/255.0, blue: 73.0/255.0, alpha: 1.0)
UINavigationBar.appearance().tintColor = UIColor.white
UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor.white]
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()
    }

}

对我有用的是,在故事板中,转到导航控制器,选择导航栏,单击属性检查器,然后将默认样式改为黑色。就是这样!

斯威夫特3

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

这是为特定的视图控制器设置状态栏背景色的解决方案。
