在你的信息。plist你需要将基于视图控制器的状态栏外观定义为任何值。

如果你定义它为YES，那么你应该在每个视图控制器中重写preferredStatusBarStyle函数。

如果你定义它为NO，那么你可以在AppDelegate中使用

UIApplication.sharedApplication().setStatusBarStyle(UIStatusBarStyle.LightContent, animated: true)

点击支持文件组(左边顶部-项目名称)。单击“信息”。点击列表之间的+，就像下面的bundle name。并添加“基于视图控制器的状态栏外观”并将其设置为NO。 然后打开AppDelegate.swift，像这样修改:

func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {

UIApplication.sharedApplication().setStatusBarStyle(UIStatusBarStyle.LightContent, animated: true)

return true
}

这是它。

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 }

自定义状态栏颜色(iOS11+， Swift4+)

如果您正在寻找如何将状态栏更改为自定义颜色的解决方案，这是可行的解决方案。

let statusBarView = UIView()
view.addSubview(statusBarView)
statusBarView.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
    statusBarView.topAnchor.constraint(equalTo: view.topAnchor),
    statusBarView.leftAnchor.constraint(equalTo: view.leftAnchor),
    statusBarView.rightAnchor.constraint(equalTo: view.rightAnchor),
    statusBarView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor)
])
statusBarView.backgroundColor = .blue

在Swift 5或xcode 11及以后的版本中设置(查看基于控制器的状态栏外观)key In info。plist为NO 然后转到项目目标，选择通用，设置状态栏样式为深色或浅色

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
}
