试试;

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

在Info.plist中添加以下内容:

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

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。

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]

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)
}
