setStatusBarHidden not working
提问by Rose Perrone
In my UIViewController, I have:
在我的UIViewController，我有：
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
[self.view sizeToFit];
}
Yet the view looks like this:
然而，视图看起来是这样的：
I'm sure this code runs. I load the view from a xib. I haven't done anything else to the status bar like change its style. What could be wrong?
我确定这段代码可以运行。我从xib. 我没有对状态栏做任何其他事情，比如改变它的风格。可能有什么问题？
Even when I set `application.statusBarHidden = YES" in my app delegate, I see:
即使我在我的应用程序委托中设置了“application.statusBarHidden = YES”，我也会看到：

In your app's plist, if you have "View controller-based status bar appearance" set to YES, put this code in the view controller in which you hide the status bar:
在您的应用程序的 plist 中，如果您将“基于视图控制器的状态栏外观”设置为“是”，请将此代码放在隐藏状态栏的视图控制器中：
- (BOOL)prefersStatusBarHidden {
return YES;
}
Else if "View controller-based status bar appearance" is set to NO, call the following whenever you want to hide the status bar.
否则，如果“查看基于控制器的状态栏外观”设置为 NO，则在您想隐藏状态栏时调用以下代码。
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];

Add to your appDelegate didFinishLaunchingWithOptions function
添加到您的 appDelegate didFinishLaunchingWithOptions 函数
application.statusBarHidden = YES;

That's because iOS 7 has changed the way it deals with the status bar.
那是因为 iOS 7 改变了它处理状态栏的方式。
Setting UIViewControllerBasedStatusBarAppearanceto NOon your app Info.plistshould work.
在您的应用程序上设置UIViewControllerBasedStatusBarAppearance为应该可以工作。NOInfo.plist

You can show/hide your app status bar using the following code (Works on IOS 7 - IOS 8 and IOS 9):
您可以使用以下代码显示/隐藏您的应用程序状态栏（适用于 IOS 7 - IOS 8 和 IOS 9）：
in your project .h file add this boolean:
在您的项目 .h 文件中添加这个布尔值：
BOOL isShowStatus;
And in .m file add this:
在 .m 文件中添加：
//To show the status bar:
-(void)showTheStatusBar
{
isShowStatus = YES;
[self setNeedsStatusBarAppearanceUpdate];
}
//And to hide the status bar:
-(void)hideTheStatusBar
{
isShowStatus = NO;
[self setNeedsStatusBarAppearanceUpdate];
}
- (BOOL)prefersStatusBarHidden {
return !isShowStatus;
}
Simply call it from anywhere, didload for example:
只需从任何地方调用它，例如 didload：
- (void)viewDidLoad
{
[super viewDidLoad];
//To show the status bar:
[self showTheStatusBar];
//Or to hide it:
[self hideTheStatusBar];
}

For me it works fine:
对我来说它工作正常：
- (BOOL)prefersStatusBarHidden {
return YES;
}
ALWAYS in the root view. If you are doing that in a subview will not work because status bar visibility will be taken from parent view.
始终在根视图中。如果您在子视图中这样做将不起作用，因为状态栏的可见性将从父视图中获取。

Try adding this after you hide the status bar:
隐藏状态栏后尝试添加：
[self.view setFrame:[self.view bounds]];
In your appdelegate.m in didFinishLaunchingWithOptions:
在您的 appdelegate.m 中didFinishLaunchingWithOptions：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
application.statusBarHidden = YES;
}
When I run your code:
当我运行你的代码时：
