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

对于Swift 4+，尝试以下代码(在Swift 4.0, 4.1 - IOS 10, 11上测试):

override var prefersStatusBarHidden: Bool { return true }

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    // call this func to force preferredStatusBarStyle to be read again.
    setNeedsStatusBarAppearanceUpdate()
}

在我的情况下，我正在寻找状态栏隐藏/显示的需求;而不是只在视图加载或消失的时候。

快3.倍

//show status bar initially
var showStatusBar = true

//set the parameters
override var prefersStatusBarHidden: Bool {

    if showStatusBar == true {

        //does not prefer status bar hidden
        print("does not prefer status bar hidden")
        return false

    } else {

        //does prefer status bar hidden
        print("does prefer status bar hidden")
    return true

    }
}

//ex: hide status bar and call parameter function again whenever you want
        showStatusBar = false
        setNeedsStatusBarAppearanceUpdate()

转到你的信息。plist和添加两个键:

斯威夫特4

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

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

斯威夫特5: 在主视图控制器中，或者主导航控制器中，

    override var preferredStatusBarStyle: UIStatusBarStyle {
        return .lightContent
    }

    override var prefersStatusBarHidden: Bool {
        return false
    }

而plist中的“View controller-based status bar appearance”必须为YES，否则上述代码将不会被调用。

如果你想在启动应用程序时隐藏状态栏， plist中的“状态栏初始隐藏”必须为YES。这可以防止发射图像失真时，额外的蓝色条显示在屏幕顶部。
