您不需要编写任何代码就可以做到这一点! 做以下使状态栏文本颜色白色通过整个应用程序

在你的项目plist文件中:

状态栏样式:透明黑色样式(alpha值为0.5) 基于视图控制器的状态栏外观:NO 状态栏初始隐藏:NO

对我来说，什么都没用。我试图改变状态栏颜色在ViewController2，这是嵌入在NavigationController，这反过来，从ViewController1被模态地呈现。这种方法行不通:

override var preferredStatusBarStyle: UIStatusBarStyle {
    return .darkContent
}

什么都没有发生，直到我找到了这个解决方案: 将这一行添加到ViewController1

导航控制器。modalPresentationCapturesStatusBarAppearance = 真正的

let navigationController = UINavigationController(rootViewController: viewController2)
navigationController.modalPresentationStyle = .overFullScreen
navigationController.modalTransitionStyle = .crossDissolve           
navigationController.modalPresentationCapturesStatusBarAppearance = true
self.present(navigationController, animated: true)

所以如果你的导航方案类似于ViewController1呈现的ViewController2，尝试modalPresentationCapturesStatusBarAppearance属性呈现的一个

文档:

The default value of this property is false. When you present a view controller by calling the present(_:animated:completion:) method, status bar appearance control is transferred from the presenting to the presented view controller only if the presented controller's modalPresentationStyle value is UIModalPresentationStyle.fullScreen. By setting this property to true, you specify the presented view controller controls status bar appearance, even though presented non-fullscreen. The system ignores this property’s value for a view controller presented fullscreen.

注:最高赞数的答案不适用于iOS 7 / 8

在信息。plist设置“视图基于控制器的状态栏外观”为NO

在AppDelegate中添加

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

to

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

此解决方案适用于iOS 7 / 8。

如果你仍然想使用基于视图控制器的状态栏的信息外观。plist设置为YES，这意味着你可以改变每个视图控制器的状态栏，在ViewDidLoad的状态栏中使用下面的白色文本:

[[[self navigationController] navigationBar] setBarStyle:UIBarStyleBlackTranslucent];

简单地调用

[[UINavigationBar appearance] setBarStyle:UIBarStyleBlack];

在

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

我的AppDelegate的方法在iOS7中非常适合我。

在信息。plist设置字段值NO查看基于控制器的状态栏外观，并在目标>常规设置中设置状态栏样式灯。
