如何在Swift iOS应用中隐藏状态栏？

Question

我想删除屏幕顶部的状态栏。这不起作用：func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: NSDictionary?)-> Bool{        application.statusBarHidden = true        return true}我也尝试过：func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: NSDictionary?)-> Bool{    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)    var controller = UIViewController()    application.statusBarHidden = true    controller.setNeedsStatusBarAppearanceUpdate()    var view = UIView(frame: CGRectMake(0, 0, 320, 568))    view.backgroundColor = UIColor.redColor()    controller.view = view    var label = UILabel(frame: CGRectMake(0, 0, 200, 21))    label.center = CGPointMake(160, 284)    label.textAlignment = NSTextAlignment.Center    label.text = "Hello World"    controller.view.addSubview(label)    self.window!.rootViewController = controller    self.window!.makeKeyAndVisible()    return true}

Answer 1

您确实应该在视图控制器上实现preferredsStatusBarHidden：

Swift 3及更高版本

override var prefersStatusBarHidden: Bool {

    return true

}

Answer 2

如果要在按钮水龙头上隐藏并恢复状态栏，而在显示和关闭幻灯片菜单，弹出窗口等时，则可以使用以下方法：

隐藏状态栏：-

UIApplication.shared.keyWindow?.windowLevel = UIWindowLevelStatusBar

恢复状态栏：-

UIApplication.shared.keyWindow?.windowLevel = UIWindowLevelNormal
