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
}

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;
}

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

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
