Swift 4.2解决方案与NavigationController

第一步:

打开你的信息。并插入一个名为“View controller based status bar appearance”或UIViewControllerBasedStatusBarAppearance的新键到YES，让每个VC使用自己的状态属性。

第二步

在每个VC中，像这样重写preferredStatusBarStyle属性:

override var preferredStatusBarStyle : UIStatusBarStyle {
    return .lightContent //.default for black style
}

最后一步

重写自定义NavigationController类中的preferredStatusBarStyle属性:

class NavigationController : UINavigationController {

override var preferredStatusBarStyle : UIStatusBarStyle {

    if let topVC = viewControllers.last {
        //return the status property of each VC, look at step 2
        return topVC.preferredStatusBarStyle  
    }

    return .default
}

警告

'statusBarStyle'的Setter在iOS 9.0中已弃用:

UIApplication.shared.statusBarStyle = .default

所以我的解决方案是这样的: 从导航控制器做一个扩展:

extension UINavigationController {
    open override var preferredStatusBarStyle: UIStatusBarStyle {
        if let topViewController = presentedViewController{
            return topViewController.preferredStatusBarStyle
        }
        if let topViewController = viewControllers.last {
            return topViewController.preferredStatusBarStyle
        }

        return .default
    }
}

如果你有一个viewController它会有另一个样式而不是app的样式，你可以做这个

var barStyle = UIStatusBarStyle.lightContent
override var preferredStatusBarStyle: UIStatusBarStyle{
    return barStyle
}

假设你的app状态样式是。default，你希望这个屏幕是。lightcontent 所以barStyle会把。lightContent作为它的默认值，这将改变状态栏的样式为lightContent，然后确保当viewWillDisappear再次改变barStyle为应用程序状态栏的样式，在我们的例子中是。default。

这对我很有用

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)

我遵循了这个教程，它对我很有效。然而，我不确定是否有任何警告。

打开你的信息。Plist和set UIViewControllerBasedStatusBarAppearance设为false。 在AppDelegate.swift中的第一个函数中，它包含didFinishLaunchingWithOptions，设置你想要的颜色。

UIApplication.sharedApplication()。statusBarStyle = UIStatusBarStyle。LightContent

Swift 3更新* 共享。statusbarstyle = .lightContent

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 }

对于没有嵌入navigationViewController的特定ViewController，只需将其添加到ViewController文件中。

override var preferredStatusBarStyle : UIStatusBarStyle {
    return .lightContent
}
