如何在Swift iOS应用程序中隐藏状态栏？

我想删除屏幕顶部的状态栏。

这不工作：

func application
(application: UIApplication,didFinishLaunchingWithOptions launchOptions: NSDictionary?)
-> Bool
{
        application.statusBarHidden = true
        return true
}

我也试过：

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(0,320,568))
    view.backgroundColor = UIColor.redColor()
    controller.view = view

    var label = UILabel(frame: CGRectMake(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
}

你真的应该实现prefeRSStatusBarHidden在你的视图控制器：

swift 2

override func prefeRSStatusBarHidden() -> Bool {
    return true
}

swift 3

override var prefeRSStatusBarHidden: Bool {
    return true
}
