你应该将这个值添加到plist: "View controller-based status bar appearance"并将其设置为"NO"。

在iOS7中隐藏状态栏:

打开你的plist-file，然后添加一个添加一行名为“基于视图控制器的状态栏外观”，并将其值设置为NO。

在Plist中添加以下属性。

Status bar is initially hidden = YES

View controller-based status bar appearance = NO

现在状态栏将被隐藏。

试试;

[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];

要在iOS7中隐藏状态栏，你需要2行代码

在应用程序中:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions写入 [[UIApplication sharedApplication] setStatusBarHidden:YES]; 在信息。加上这个 基于视图-控制器的状态栏外观= NO

在viewdidload中添加以下行

  [[UIApplication sharedApplication] setStatusBarHidden:YES
                                        withAnimation:UIStatusBarAnimationFade];

并添加新方法

  - (BOOL)prefersStatusBarHidden {
          return YES;
  }

同时更改信息。plist文件 查看基于控制器的状态栏外观" = NO

这对我很有用

从UIKit > UIApplication.h:

// Setting statusBarHidden does nothing if your application is using the default UIViewController-based status bar system.
@property(nonatomic,getter=isStatusBarHidden) BOOL statusBarHidden;
- (void)setStatusBarHidden:(BOOL)hidden withAnimation:(UIStatusBarAnimation)animation NS_AVAILABLE_IOS(3_2);

所以应该将基于视图控制器的状态栏外观设置为NO

在Info.plist中添加以下内容:

<key>UIStatusBarHidden</key>
<true/>
<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>

试试这个简单的方法:

objective - c:

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated]
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
}

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated]
    [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];
}

迅速:

override func viewWillAppear(animated: Bool) 
{
    super.viewWillAppear(animated)
    UIApplication.sharedApplication().setStatusBarHidden(true, withAnimation: UIStatusBarAnimation.None)
}

override func viewWillDisappear(animated: Bool) 
{
    super.viewWillDisappear(animated)
    UIApplication.sharedApplication().setStatusBarHidden(false, withAnimation: UIStatusBarAnimation.None)
}

为了更好地理解，添加一些带有评论的照片:

App在任何更改前

在名为“支持文件”的Project Navigator文件夹中找到，然后单击*。plist文件

之后你会得到不同的设置你的应用程序显示。你需要添加2个键UIStatusBarHidden和UIViewControllerBasedStatusBarAppearance。你可以简单地点击+按钮

按下+键后，你可以选择其中一个键开始打字。

正确的版本:

最后，在应用这些变化之后:

另外，你可以在这里找到另一种解决方案

你应该将这个值添加到plist: "View controller-based status bar appearance"并将其设置为"NO"。

我做了以下操作，它似乎是有效的(即使在iOS 8中):

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) {

        [[UIApplication sharedApplication] setStatusBarHidden:YES];
    }
}

- (BOOL)prefersStatusBarHidden {
    return YES;
}

要回答Susitha的问题:使用setNeedsStatusBarAppearanceUpdate。这将调用prefersStatusBarHidden来刷新你想要的状态栏状态。试试这个:

    @property (nonatomic, getter=isHideStatusBar) BOOL hideStatusBar; // Give this a default value early

    - (BOOL)prefersStatusBarHidden {
        return self.isHideStatusBar;
    }

    - (void)someMethod {
    // triggered by an event or user action
    [self setHideStatusBar:YES];
    [self setNeedsStatusBarAppearanceUpdate];
    }

如果您想再次看到状态栏，请将属性hideStatusBar(或任何您所调用的属性)设置为NO。通过另一个调用来间接调用preferStatusBarHidden

[self setNeedsStatusBarAppearanceUpdate]

以下是Swift版本(iOS9之前):

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    UIApplication.sharedApplication().setStatusBarHidden(true, withAnimation: UIStatusBarAnimation.None)
}

override func viewWillDisappear(animated: Bool) {
    super.viewWillDisappear(animated)
    UIApplication.sharedApplication().setStatusBarHidden(false, withAnimation: UIStatusBarAnimation.None)
}

这也适用于(iOS7+):

override func prefersStatusBarHidden() -> Bool {
    return true
}

你还需要调用:

setNeedsStatusBarAppearanceUpdate()

在viewDidLoad()中。

注意，如果你使用SplitView控制器，或者其他容器视图控制器，你还需要让它在发送childViewControllerForStatusBarHidden时返回你的类。一种方法是为statusController设置一个公共弱变量，并在这个被重写的方法中返回它。

UIApplication。setStatusBarX在iOS9已弃用 在info.plist中不推荐使用UIViewControllerBasedStatusBarAppearance=NO 我们应该在所有的视图控制器中使用preferredStatusBarX

但当涉及到UINavigationController时，它会变得更有趣:

If navigationBarHidden = true, the child UIViewController's preferredStatusBarX are called, since the child is displaying the content under the status bar. If navigationBarHidden = false, the UINavigationController's preferredStatusBarX are called, after all it is displaying the content under the status bar. The UINavigationController's default preferredStatusBarStyle uses the value from UINav.navigationBar.barStyle. .Default = black status bar content, .Black = white status bar content. So if you're setting barTintColor to some custom colour (which you likely are), you also need to set barStyle to .Black to get white status bar content. I'd set barStyle to black before setting barTintColor, in case barStyle overrides the barTintColor. An alternative is that you can subclass UINavigationController rather than mucking around with bar style. HOWEVER, if you subclass UINavigationController, you get no control over the status bar if navigationBarHidden = true. Somehow UIKit goes direct to the child UIViewController without asking the UINavigationController in this situation. I would have thought it should be the UINavigationController's responsibility to ask the child >shrugs<. And modally displayed UIViewController's only get a say in the status bar if modalPresentationStyle = .FullScreen. If you've got a custom presentation style modal view controller and you really want it to control the status bar, you can set modalPresentationCapturesStatusBarAppearance = true.

iOS中隐藏状态栏的步骤 1. AppDelegate开放。M文件，添加应用程序。statusbar隐藏在didFinishLaunchingWithOptions方法中

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    application.statusBarHidden = YES;
    return YES;
    }

开放的信息。Plist和set

查看基于控制器的状态栏外观设置NO

iOS 9起:

由于statusBarHidden方法已从iOS9中弃用，您需要在plist中添加如下两个值:

<key>UIStatusBarHidden</key>
<true/>
<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>

请参考以下图片:

statusBarHidden从iOS9被弃用:

@property(重述，非atomic,getter= isstatus barhiden) BOOL 新闻记者:新闻记者 prefersStatusBarHidden”)__TVOS_PROHIBITED;

在iOS10中，我所需要做的就是覆盖我的RootViewController (Swift)中的prefersStatusBarHidden变量:

override var prefersStatusBarHidden: Bool {
    return true
}

Swift 3更新:

更新信息。请输入以下信息:

基于视图控制器的状态栏外观:NO

然后，在ViewController或其他地方:

isstatusbarhidden = true

固定解决方案SWIFT 3+ (iOS 9, 10)

1-在信息。请在属性下面设置

2-粘贴下面的代码到根控制器，以

 private var isStatusBarHidden = true {
        didSet {
            setNeedsStatusBarAppearanceUpdate()
        }
    }

    override var prefersStatusBarHidden: Bool {
        return isStatusBarHidden
    }

你可以调用isStatusBarHidden = true和isStatusBarHidden = false来隐藏/显示状态栏

斯威夫特5

使用以下步骤隐藏iOS状态栏:

打开Info.plist。 添加新的键视图控制器的状态栏外观和值设置为NO。 添加新键状态栏初始隐藏，值设置为YES。 编译项目。 状态栏应该隐藏在iOS手机现在。
