我想刪除屏幕頂部的狀態欄。這不起作用：func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: NSDictionary?)-> Bool{ application.statusBarHidden = true return true}我也嘗試過：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}

您確實應該在視圖控制器上實現preferredsStatusBarHidden：
Swift 3及更高版本
override var prefersStatusBarHidden: Bool {
return true
}

如果要在按鈕水龍頭上隱藏并恢復狀態欄，而在顯示和關閉幻燈片菜單，彈出窗口等時，則可以使用以下方法：
隱藏狀態欄：-
UIApplication.shared.keyWindow?.windowLevel = UIWindowLevelStatusBar
恢復狀態欄：-
UIApplication.shared.keyWindow?.windowLevel = UIWindowLevelNormal
