我如何隐藏在一个Swift iOS应用程序的状态栏?

我想移除屏幕顶部的状态栏。

这行不通:

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, 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
}

只是补充，当覆盖prefersStatusBarHidden方法或变量时，基于视图控制器的状态栏出现在信息中。plist必须为YES，否则重写将不起作用

在信息。plist设置基于控制器的状态栏外观为NO

调用uiapplication。shared。isstatusbarhidden = true

这对我来说是个问题，因为iOS 9不支持上面提到的任何方法，比如UIApplication.sharedApplication()。statusBarHidden = true 或

UIApplication.sharedApplication().setStatusBarHidden(true, withAnimation: UIStatusBarAnimation.None)

and

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

工作，但不提供可编程的解决方案，我可以改变的条件。 (statusBarHidden = true和statusBarHidden = false，就像我们之前做的那样)。

解决这种疯狂的方法:

通过添加prefersStatusBarHidden()像下面这样，你可以通过编程控制隐藏和显示状态栏，而不需要添加UIViewControllerBasedStatusBarAppearance设置到你的info.plist:

var showStatusBar = true

override func prefersStatusBarHidden() -> Bool {
     if showStatusBar {
         return false
     }
     return true
}

private func showStatusBar(enabled: Bool) {
    showStatusBar = enabled
    prefersStatusBarHidden()
}

然后在代码中像这样使用它:

//Hide Status Bar
showStatusBar(false)

//Show Status Bar
showStatusBar(true)

在Swift 3.x:

override func viewWillAppear(_ animated: Bool) {
    UIApplication.shared.isStatusBarHidden = true
}

Go to Info.plist file Hover on one of those lines and a (+) and (-) button will show up. Click the plus button to add new key Type in start with capital V and automatically the first choice will be View controller-based status bar appearance. Add that as the KEY. Set the VALUE to "NO" Go to you AppDelegate.swift Add the code, inside the method func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject:AnyObject]?) -> Bool { application.statusBarHidden = true return true }

完成了!运行您的应用程序，没有更多的状态栏!

转到你的信息。plist和添加两个键:
