在Info.plist中添加以下内容:

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

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

在Info.plist中添加以下内容:

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

试试;

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

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

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)
}
