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

我使用的是Xcode 8.1 (8B62)，部署目标设置为10.1，上面提到的覆盖选项我没有太多的运气。然而，检查部署信息中的“隐藏状态栏”选项对我来说是有用的。

我希望这能有所帮助。

其他回答

一个对我有效的解决方案;如果你想在加载时隐藏特定视图控制器上的状态栏:

import UIKit

class ViewController: UIViewController {

private var hideStatusBar: Bool = false

override var prefersStatusBarHidden: Bool {
    return hideStatusBar
}

override var preferredStatusBarUpdateAnimation: UIStatusBarAnimation {
    return UIStatusBarAnimation.slide
}

override func viewDidLoad() {
    super.viewDidLoad()

    view.backgroundcolor = .white
    hideStatusBar = true

    UIView.animate(withDuration: 0.3) {
        self.setNeedsStatusBarAppearanceUpdate()
    }
}

注意:如果你在你的信息中设置了“基于控制器的状态栏外观”为“NO”。请列出上面的代码不工作。你应该将键设置为“YES”或者从info.plist中删除它

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()
}

iOS 10 / Swift 3.0更新

不再是函数，现在是属性…

override var prefersStatusBarHidden: Bool {
    return true
}

在Swift 4.2中，它现在是一个属性。

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!
