Swift-3

斯威夫特-3

 override var prefersStatusBarHidden: Bool {  
    return true  
}  

I got the Information From Here

我从这里得到信息

• Change functo var

• Delete ()

• Change ->to :

• 更改func为var

• 删除 ()

• 更改->为:

This works because a computed variable has a getter function, so the function you were implementing before simply turns into the getter function

这是有效的，因为计算变量有一个 getter 函数，所以你之前实现的函数只是变成了 getter 函数

2016 onwards: simple Thing like

2016 年起：简单的事情就像

On your info.plist add the following two property for statusBar Hidden

在 info.plist 上为 statusBar Hidden 添加以下两个属性

View controller-based status bar appearance (Boolean: NO)

查看基于控制器的状态栏外观（布尔值：NO）

Status bar is initially hidden (Boolean: YES)

状态栏最初是隐藏的（布尔值：YES）

By Source

按来源

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

Old answers ! ...

旧答案！...

1. add application.statusBarHiddenin didFinishLaunchingWithOptions

   - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
   // Override point for customization after application launch.
   application.statusBarHidden = YES;
   return YES;
   }
   

1. 添加application.statusBarHidden在didFinishLaunchingWithOptions

   - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
   // Override point for customization after application launch.
   application.statusBarHidden = YES;
   return YES;
   }
   

and add

并添加

1. in info.plistadd this View controller-based status bar appearanceset NO

   View controller-based status bar appearance = NO
   

2. 在info.plist添加这个View controller-based status bar appearance集合NO

   View controller-based status bar appearance = NO
   

viewcontroller based hidden set

基于视图控制器的隐藏集

Add method in your view controller.

在视图控制器中添加方法。

目标-C

- (BOOL)prefersStatusBarHidden {
    return YES;
}

Swift upto 2

快速到 2

override func prefersStatusBarHidden() -> Bool {
return true
}

(GOOD) 2016.5.17 in iOS 9.0 worked nicely.

（好）iOS 9.0 中的 2016.5.17 运行良好。

更新答案

1. Go to Info.plist file
2. Hover on one of those lines and a (+) and (-) button will show up.
3. Click the plus button to add new key
4. Type in start with capital Vand automatically the first choice will be View controller-based status bar appearance. Add that as the KEY.
5. Set the VALUE to "NO"
6. Go to you AppDelegate.m for Objective-C (for swift language: AppDelegate.swift)
7. Add the code, inside the method

1. 转到 Info.plist 文件
2. 将鼠标悬停在其中一行上，将显示 (+) 和 (-) 按钮。
3. 单击加号按钮添加新密钥
4. 输入以大写 V 开头，第一个选项会自动成为View controller-based status bar appearance。将其添加为 KEY。
5. 将值设置为“否”
6. 转到你的 AppDelegate.m for Objective-C（对于 swift 语言： AppDelegate.swift）
7. 在方法内添加代码

I know that the documentation of setStatusBarHidden:does not mention on what use instead. But the header of UIApplicationdoes.

我知道文档setStatusBarHidden:没有提到使用什么。但标题UIApplication确实如此。

// Setting statusBarHidden does nothing if your application is using the default UIViewController-based status bar system.
@property(readwrite, nonatomic,getter=isStatusBarHidden) BOOL statusBarHidden NS_DEPRECATED_IOS(2_0, 9_0, "Use -[UIViewController prefersStatusBarHidden]");
- (void)setStatusBarHidden:(BOOL)hidden withAnimation:(UIStatusBarAnimation)animation NS_DEPRECATED_IOS(3_2, 9_0, "Use -[UIViewController prefersStatusBarHidden]");

Here is stated that you should use the prefersStatusBarHiddenon UIViewControllerand use view controller based statusbar styles.

这里声明您应该使用prefersStatusBarHiddenonUIViewController并使用基于视图控制器的状态栏样式。

All you need to do now is configure whether the view controller needs to show of hide the status bar. Like so :

您现在需要做的就是配置视图控制器是否需要显示或隐藏状态栏。像这样：

- (BOOL)prefersStatusBarHidden {
   return YES;
}

Here's how do you easily return a control over status bar visibility for iOS 9+and Swift 3+:

以下是如何轻松返回对iOS 9+和Swift 3+状态栏可见性的控制：

1. Add View controller-based status bar appearancekey with YESvalue to Info.plist.

2. Add this variable to the view controller:

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

3. Override prefersStatusBarHiddenproperty:

   override var prefersStatusBarHidden: Bool {
       return isStatusBarHidden
   }
   

1. 将View controller-based status bar appearance带YES值的键添加到Info.plist.

2. 将此变量添加到视图控制器：

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

3. 覆盖prefersStatusBarHidden属性：

   override var prefersStatusBarHidden: Bool {
       return isStatusBarHidden
   }
   

That's it. Now you are able to call isStatusBarHidden = trueand isStatusBarHidden = falsewhenever you want.

就是这样。现在，您可以打电话isStatusBarHidden = true和isStatusBarHidden = false只要你想。

An easy approach would be to set the windowLevelof the Application to be either normal or statusBar based on your needs, so to start

一个简单的方法是windowLevel根据您的需要将应用程序的设置为 normal 或 statusBar，因此开始

Objective-C

目标-C

To Hide the Status Bar

隐藏状态栏

 UIApplication.sharedApplication.keyWindow.windowLevel = UIWindowLevelStatusBar;

To Show the Status Bar

显示状态栏

 UIApplication.sharedApplication.keyWindow.windowLevel = UIWindowLevelNormal;

Also add the Key(View controller-based status bar appearance) with boolean value NO.

还添加布尔值 NO Key（基于视图控制器的状态栏外观）。

回答by budidino

If for some reason you need View controller-based status bar appearanceequal to YES(for example to keep status bar white)

如果出于某种原因您需要View controller-based status bar appearance等于YES（例如保持状态栏为白色）

on AppDelegate's didFinishLaunchingWithOptionsmethod or wherever you setup your navigationController:

在 AppDelegate 的didFinishLaunchingWithOptions方法或您设置导航控制器的任何地方：

yourNavigationController.navigationBar.barStyle = .black

then use alex-staravoitau's awesome answer and add this code wherever you'll be hiding the status bar:

然后使用alex-staravoitau的很棒的答案，并在隐藏状态栏的任何地方添加此代码：

override var preferredStatusBarStyle: UIStatusBarStyle {
  return .lightContent
}

I'm not sure if this is the right way to achieve this result, but it worked for me and I hope it helps someone else too :)

我不确定这是否是实现此结果的正确方法，但它对我有用，我希望它也能帮助其他人:)
