UIApplication.sharedApplication().setStatusBarStyle() deprecated in iOS 9

提问by Rick

I have been using

我一直在使用

UIApplication.sharedApplication().setStatusBarStyle()

In my appDelegate and it has worked fine, but since iOS 9, this method is deprecated and I can't find an alternative.

在我的 appDelegate 中，它运行良好，但自 iOS 9 以来，此方法已被弃用，我找不到替代方法。

I want to change the statusbar style to .LightContent for my whole application, but the only suggestion xCode gives me is to handle this in every VC separately with;

我想将整个应用程序的状态栏样式更改为 .LightContent，但 xCode 给我的唯一建议是在每个 VC 中分别处理此问题；

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

Has anyone an idea how to do this for the whole application?

有没有人知道如何为整个应用程序做到这一点？

Thanks in advance

I think I have found a solution. I ended up setting the

我想我已经找到了解决办法。我最终设置了

View controller-based status bar appearanceboolean to NO

View controller-based status bar appearance布尔值 NO

In my info.plist file.

在我的 info.plist 文件中。

Then I went to my target's General settings -> Deployment infoand changed the dropdown option Status Bar Styleto Lightinstead of Default

然后我去我的目标的General settings -> Deployment info，改变了下拉选项 Status Bar Style来Light代替Default

This changed the statusbar style to Lightfor my whole application, just what I wanted.

这改变了Light我整个应用程序的状态栏样式，正是我想要的。

I Hope this helps!

我希望这有帮助！

This worked fine for me in Xcode 7.

这在 Xcode 7 中对我来说效果很好。

In AppDelegate:

在 AppDelegate 中：

UIApplication.sharedApplication().statusBarStyle = .LightContent

for those still working with Swift 3 in Xcode 8:

对于那些仍在 Xcode 8 中使用 Swift 3 的人：

( slightly different to Marlon Ruiz's answer above, not an override function, but within viewDidLoad )

（与上面 Marlon Ruiz 的回答略有不同，不是覆盖函数，而是在 viewDidLoad 中）

override func viewDidLoad() {
    super.viewDidLoad()

    var preferredStatusBarStyle: UIStatusBarStyle {
        return .lightContent
    }
}

In info.plist, set: View controller-based status bar appearanceboolean to NO

在 info.plist 中，设置： View controller-based status bar appearanceboolean 为NO

In app delegate's didFinishLaunchingWithOptions, use function parameter application(and not the [UIApplication sharedApplication]or simillary the UIApplication.sharedApplication()in swift) to set this like so:

在 app delegate's 中didFinishLaunchingWithOptions，使用函数参数application（而不是swift 中的[UIApplication sharedApplication]或UIApplication.sharedApplication()类似的）来设置它，如下所示：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    application.statusBarStyle = UIStatusBarStyleLightContent;
}

This is the new way in AppDelegate:

这是 AppDelegate 中的新方法：

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