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]

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

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

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)
}

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
}

在Info.plist中添加以下内容:

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