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
}

在我的例子中，我需要根据某些条件更新隐藏的状态栏。

因此，我创建了一个包含新属性hideStatusBar的基本控制器BaseViewController。

其他视图控制器是这个基控制器的子类。最后，当我想要更新状态栏行为时，我只需要更改这个hideStatusBar值。

class BaseViewController: UIViewController {

    var hideStatusBar: Bool = false {
        didSet {
            setNeedsStatusBarAppearanceUpdate()
        }
    }

    override var prefersStatusBarHidden: Bool {
           return hideStatusBar
    }
}

如何使用

final class ViewController: BaseViewController, UIScrollViewDelegate {
    let scrollView = UIScrollView()

    ...

    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        UIView.animate(withDuration: 0.3) {
            if scrollView.contentOffset.y > 100 {
                self.hideStatusBar = true
            } else {
                self.hideStatusBar = false
            }
        }
    }
}

Demo

这是一个演示，我使用UIView.animate(…)使过渡更流畅。

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!

其实这是我自己发现的。我将添加我的解决方案作为另一种选择。

extension UIViewController {
    func prefersStatusBarHidden() -> Bool {
        return true
    }
}

如果你是模态呈现视图控制器，试试

viewController.hidesBottomBarWhenPushed = true
viewController.modalPresentationCapturesStatusBarAppearance = true

你真的应该在你的视图控制器上实现prefersStatusBarHidden:

Swift 3及后续版本

override var prefersStatusBarHidden: Bool {
    return true
}

斯威夫特3

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
