How to set status bar style to light content on iOS7?
提问by Upvote
I tried several solutions from SO for this problem but none of them worked for me. I created a new iOS7 project with one simple view. I tried setting
我为这个问题尝试了 SO 的几种解决方案，但没有一个对我有用。我用一个简单的视图创建了一个新的 iOS7 项目。我试过设置
View controller-based status bar appearance to NO
and in AppDelegate:
并在 AppDelegate 中：
[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent animated:NO];
However this removes the status bar completely.
但是，这会完全删除状态栏。
Without the View controller-based status bar appearance option, Regardless what I set for Status bar style in the plist file, the status bar text is still black. I need it to be white for the entire application. Is this possible?
如果没有基于视图控制器的状态栏外观选项，无论我在 plist 文件中为状态栏样式设置了什么，状态栏文本仍然是黑色的。我需要它在整个应用程序中都是白色的。这可能吗？
I am on latest xcode version.

did you try it without "Animated:No" ?
你在没有“Animated:No”的情况下尝试过吗？
Go to Info tab of the project target, Add Row:
转到项目目标的信息选项卡，添加行：
UIViewControllerBasedStatusBarAppearance, set value NO
UIViewControllerBasedStatusBarAppearance，设置值 NO
Then in appdelegate.m
然后在 appdelegate.m
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
[application setStatusBarStyle:UIStatusBarStyleLightContent];
}
This should set it application wide.
这应该将其设置为广泛应用。

The Accepted answer seemed to work sometimes. I found out that the UIViewController can change the status bar style also. To get around this and always work, cause I didn't need the UIViewControllers controlling the status bar, I had to set UIViewControllerBasedStatusBarAppearanceto NOin my Info.plist
接受的答案有时似乎有效。我发现 UIViewController 也可以更改状态栏样式。为了解决这个问题，总是工作，因为我并不需要UIViewControllers控制状态栏，我不得不设置UIViewControllerBasedStatusBarAppearance到NO我Info.plist

Use needsStatusBarAppearanceUpdateto update status bar in viewDidLoad:method of view controller
用于needsStatusBarAppearanceUpdate在viewDidLoad:视图控制器的方法中更新状态栏
[self setNeedsStatusBarAppearanceUpdate];
Now add below method into view controller:
现在将以下方法添加到视图控制器中：
- (UIStatusBarStyle) preferredStatusBarStyle {
return UIStatusBarStyleLightContent;
}

I would go with Logan's answer. As of iOS 9, UIApplication's setStatusBarStyle:method is deprecated anyway, so you'll want to start moving away from using that. The preferred method, now is to implement preferredStatusBarStylewithin your ViewControllerlike Logan has described.
我会同意洛根的回答。从 iOS 9 开始，setStatusBarStyle:无论如何都不推荐使用UIApplication 的方法，因此您将希望开始不再使用它。首选方法，现在是preferredStatusBarStyle在您ViewController像 Logan 所描述的那样实施。
