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
}

当前回答

 override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(true);
    navigationController?.navigationBar.hidden = true // for navigation bar hide
    UIApplication.sharedApplication().statusBarHidden=true; // for status bar hide
}

其他回答

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)

iOS 10 / Swift 3.0更新

不再是函数，现在是属性…

override var prefersStatusBarHidden: Bool {
    return 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!

如果你更喜欢可视化的方法而不是编码，请使用以下方法: 在你的info.plist

简单地添加基于视图控制器的状态栏外观为NO

和状态栏最初隐藏为YES

斯威夫特4

//MARK:- Show Status Bar
UIApplication.shared.isStatusBarHidden = false

//MARK:- Hide Status Bar
UIApplication.shared.isStatusBarHidden = true
