Using a UINavigationControllerand setting its navigation bar's barStyleto .Black. past this line in your AppDelegate.mfile.

使用 aUINavigationController并将其导航栏设置barStyle为.Black。在您的AppDelegate.m文件中超过这一行。

navigationController.navigationBar.barStyle = UIBarStyleBlack;

If you are not using UINavigationControllerthen add following code in your ViewController.mfile.

如果您不使用，UINavigationController则在您的ViewController.m文件中添加以下代码。

- (UIStatusBarStyle)preferredStatusBarStyle
{
    return UIStatusBarStyleLightContent;
}

And call the method to this line :

并将方法调用到这一行：

[self setNeedsStatusBarAppearanceUpdate];

First set

第一套

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

Go to your AppDelegate, find itsdidFinishLaunchingWithOptionsmethod and do:

转到您的 AppDelegate，找到它的didFinishLaunchingWithOptions方法并执行以下操作：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

}

and then set View controller-based status bar appearanceequal to NO in plist.

然后View controller-based status bar appearance在 plist 中设置为等于 NO。

1. Add a key in your info.plistfile UIViewControllerBasedStatusBarAppearanceand set it to YES.

2. In viewDidLoad method of your ViewController add a method call:

   [self setNeedsStatusBarAppearanceUpdate];
   

3. Then paste the following method in viewControllerfile:

   - (UIStatusBarStyle)preferredStatusBarStyle
   { 
       return UIStatusBarStyleLightContent; 
   }
   

1. 在您的info.plist文件中添加一个密钥UIViewControllerBasedStatusBarAppearance并将其设置为YES.

2. 在 ViewController 的 viewDidLoad 方法中添加一个方法调用：

   [self setNeedsStatusBarAppearanceUpdate];
   

3. 然后将以下方法粘贴到viewController文件中：

   - (UIStatusBarStyle)preferredStatusBarStyle
   { 
       return UIStatusBarStyleLightContent; 
   }

Add the key View controller-based status bar appearanceto Info.plistfile and make it boolean type set to NO.

将密钥添加View controller-based status bar appearance到Info.plist文件并将其布尔类型设置为NO.

Insert one line code in viewDidLoad(this works on specific class where it is mentioned)

插入一行代码viewDidLoad（这适用于提到它的特定类）

 [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

iOS Status bar has only 2 options (black and white). You can try this in AppDelegate:

iOS 状态栏只有 2 个选项（黑色和白色）。你可以在 AppDelegate 中试试这个：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
    [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleLightContent];
}
