固定解决方案SWIFT 3+ (iOS 9, 10)

1-在信息。请在属性下面设置

2-粘贴下面的代码到根控制器，以

 private var isStatusBarHidden = true {
        didSet {
            setNeedsStatusBarAppearanceUpdate()
        }
    }

    override var prefersStatusBarHidden: Bool {
        return isStatusBarHidden
    }

你可以调用isStatusBarHidden = true和isStatusBarHidden = false来隐藏/显示状态栏

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)
}

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

你应该将这个值添加到plist: "View controller-based status bar appearance"并将其设置为"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

要在iOS7中隐藏状态栏，你需要2行代码

在应用程序中:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions写入 [[UIApplication sharedApplication] setStatusBarHidden:YES]; 在信息。加上这个 基于视图-控制器的状态栏外观= NO
