override func preferredStatusBarStyle() -> UIStatusBarStyle {
 return UIStatusBarStyle.LightContent;
}

使用上述代码在任何ViewController中为特定的ViewController设置状态栏颜色为白色,在iOS8中对我来说是行不通的。有什么建议吗?使用UIApplication。shared应用方法,在信息中需要更改后颜色更改。Plist为整个应用程序。

// Change the colour of status bar from black to white
UIApplication.sharedApplication().statusBarStyle = .LightContent

我怎么能改变一些必要的和特定的视图控制器的状态栏颜色?

对于swift 3

.plist

View controller-based status bar appearance = NO

AppDelegate.swift

  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Custom statubar
        UIApplication.shared.isStatusBarHidden = false
        UIApplication.shared.statusBarStyle = .lightContent
        let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as! UIView
        statusBar.backgroundColor = UIColor.gray

        return true
    }

其他回答

我在Swift 5、Swift 4.2中使用这种方式。

在Info.plist中添加下一个值:

UIViewControllerBasedStatusBarAppearance = YES

or

UIViewControllerBasedStatusBarAppearance = NO(查看变化)

UIStatusBarHidden = NO

UIStatusBarStyle = UIStatusBarStyleDefault(或设置为UIStatusBarStyleLightContent,如果你想在启动时看到轻状态栏文本)

然后将代码放置到您想要看到浅色内容的特定视图控制器(要看到深色文本,请将preferredStatusBarStyle设置为. darkcontent)。

override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
}

override func viewDidLoad() {
    super.viewDidLoad()

    if let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as? UIView {
        statusBar.backgroundColor = .sunflowerYellow
    }
}

我在这个问题上遇到了一些麻烦。我不太喜欢在视图中全局改变状态栏的颜色,然后在视图中改变它,然后像接受的答案一样消失。信不信由你,你可以通过在你想要的视图控制器上重写preferredStatusBarStyle来实现。经过很长一段时间,这是我所做的让它工作:

Change View controller-based status bar appearance in your info.plist to YES. Now any full screen view controller can change the status bar style by overriding preferredStatusBarStyle. I specify full screen because this will not work for (non-full screen) modal view controllers, not without setting modal​Presentation​Captures​Status​Bar​Appearance to Yes that is. Also if you have embedded view controllers, like in a navigation controller for example, it will ask the top most view controller for status bar style. Overriding child​View​Controller​For​Status​Bar​Style and passing the embedded view controller is supposed to work but it didn't for me. So I just returned the embedded view controllers preferred status bar as the preferred status bar style. Something like this: override var preferredStatusBarStyle: UIStatusBarStyle { if let topViewController = viewControllers.last { return topViewController.preferredStatusBarStyle } return .default }

实现preferredStatusBarStyle,如你所述,并调用self.setNeedsStatusBarAppearanceUpdate()在ViewDidLoad和 也在信息。设置UIViewControllerBasedStatusBarAppearance为YES(默认是YES)

目前还不清楚为什么它不起作用。我需要检查代码。另一个建议是 使用viewDidLoad UIApplication.sharedApplication()中的工作代码。statusBarStyle = . lightcontent,并将此更改为默认值,当您查看viewgetdisappear viewWillDisappear。

在我的情况下,我使用故事板来组织我的视图控制器。我想改变所有的状态栏风格。

你可以在下面的图片中看到。

Stars View Controller是一个CPBaseNavigationController,而CPBaseNavigationController是UINavigationController的子类。

我试着做下面的步骤:

在AppDelegate.swift func didFinishLaunchingWithOptions中添加 //更改状态栏颜色 UIApplication.sharedApplication()。statusBarHidden = false UIApplication.sharedApplication()。statusBarStyle = .LightContent 但没有效果。 在StoryBoard中,找到Base Tab BarController(上图)。选择属性检查器,将状态条属性更改为轻内容。太糟糕了,没有效果。

最后我明白了。在我的自定义导航控制器CPBaseNavigationController中添加func preferredStatusBarStyle override func preferredStatusBarStyle() -> UIStatusBarStyle { 返回.LightContent } 它工作得很好!

此外,statusBarStyle在9.0中已弃用,你可以使用-[UIViewController preferredStatusBarStyle]。

在Swift 3.0 Xcode 8中,一切都要简单得多

使用下面的代码在应用程序委托文件,之后

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

插入:

UINavigationBar.appearance().barStyle = .black

UINavigationBar.appearance().barTintColor = UIColor(red: 230, green: 32, blue: 31, alpha: 1.0)
