在TabbarViewController中隐藏特定视图控制器中的状态栏

Question

我有TabbarViewController。在一个选项卡中，当导航到特定ViewController（详细信息图像视图）时，我想隐藏状态栏。 我看过这个链接： How to hide a status bar in iOS?

但在我的情况下，它不起作用，因为我不想在整个应用程序中隐藏状态栏，而只是在特定的ViewController中。

有没有办法只在某个标签中实现隐藏滚动条？

*编辑： 我想隐藏状态栏的ViewController是一个PageViewController。这是问题吗？

    -(void) viewDidAppear:(BOOL)animated{
        [super viewDidAppear:YES];
        if([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationLandscapeLeft || [UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationLandscapeRight){
        if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]){
            [self prefersStatusBarHidden];
            [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
            [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
        }
        else{
            // iOS 6
            [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
        }

    }
    else if([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortrait || [UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortraitUpsideDown){
        if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]){
            [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
            [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
        }
        else{
            // iOS 6
            [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
        }
    }
}

-(UIStatusBarStyle)preferredStatusBarStyle{
    return UIStatusBarStyleLightContent;
}
- (BOOL)prefersStatusBarHidden {
    return YES;
}

请尝试以下代码：

    [UIApplication sharedApplication].statusBarHidden = YES;
}
