ios - 如何在 React Native 中设置 iOS 状态栏背景颜色？

Question

react native iOS 本机代码中是否有一个地方可以修改以设置 iOS 状态栏背景颜色？RCTRootView.m ?

react native StatusBar组件仅支持Android的backgroundColor。

iOS 操作系统似乎允许设置状态栏背景颜色

我的目标是使状态栏颜色更深。

Answer 1

iOS 没有状态栏 bg 的概念。以下是您如何以跨平台方式实现这一目标：

import React, {
  Component,
} from 'react';
import {
  AppRegistry,
  StyleSheet,
  View,
  StatusBar,
  Platform,
  SafeAreaView
} from 'react-native';

const MyStatusBar = ({backgroundColor, ...props}) => (
  <View style={[styles.statusBar, { backgroundColor }]}>
    <SafeAreaView>
      <StatusBar translucent backgroundColor={backgroundColor} {...props} />
    </SafeAreaView>
  </View>
);

class DarkTheme extends Component {
  render() {
    return (
      <View style={styles.container}>
        <MyStatusBar backgroundColor="#5E8D48" barStyle="light-content" />
        <View style={styles.appBar} />
        <View style={styles.content} />
      </View>
    );
  }
}

const STATUSBAR_HEIGHT = StatusBar.currentHeight;
const APPBAR_HEIGHT = Platform.OS === 'ios' ? 44 : 56;

const styles = StyleSheet.create({
  container: {
    flex: 1,
  },
  statusBar: {
    height: STATUSBAR_HEIGHT,
  },
  appBar: {
    backgroundColor:'#79B45D',
    height: APPBAR_HEIGHT,
  },
  content: {
    flex: 1,
    backgroundColor: '#33373B',
  },
});

AppRegistry.registerComponent('App', () => DarkTheme);

Answer 2

添加import { StatusBar } from 'react-native';到您的顶部，app.js然后添加StatusBar.setBarStyle('light-content', true);为您的第一行render()以将状态栏文本/图标更改为白色。

其他颜色选项是'default'和'dark-content'。

有关详细信息，请参阅https://facebook.github.io/react-native/docs/statusbar.html。

除此之外：不，您必须点击您提供的链接。

Answer 3

如果你使用 react-native-navigation，你需要：

1-) 将此添加到您的 info.plist 文件中：

<key>UIViewControllerBasedStatusBarAppearance</key>
<string>YES</string>

2-) 在render()函数的第一行，例如：

  render(){
    this.props.navigator.setStyle({
      statusBarTextColorScheme: 'light'
    });
    return (
      <Login navigator={this.props.navigator}></Login>
    );
  }

此示例将您的状态栏转换为浅色文本/按钮/图标颜色。

在 react-native 中设置 iOS 和 Android 状态栏背景颜色

    import React, { Component } from 'react';
    import { Platform, StyleSheet, View, StatusBar } from 'react-native';
    import Constants from 'expo-constants';


    class Statusbar extends Component {

        render() {
            return (
                <View style={styles.StatusBar}>
                    <StatusBar translucent barStyle="light-content" />
                </View>
            );
        }
    }

    const styles = StyleSheet.create({
        StatusBar: {
            height: Constants.statusBarHeight,
            backgroundColor: 'rgba(22,7,92,1)'
        }
    });

    export default Statusbar;

Answer 5

你需要自定义它。如果您使用SafeAreaView，
则 StatusBar 不是 ios 屏幕布局的一部分reac-native

而是使用react-native-safe-area-context并对其进行自定义。

看到这个小吃。

Answer 6

添加到根视图。（如果有，则超出 SafeAreaView）

{Platform.OS === 'ios' &&
 <View style={{
     width: "100%",
     height: 100, // For all devices, even X, XS Max
     position: 'absolute',
     top: 0,
     left: 0,
     backgroundColor: "red"}}
/>}
// App screen
...

Answer 7

import {SafeAreaConsumer} from 'react-native-safe-area-context';

<SafeAreaConsumer>
{(insets)=>(
<View style={{flex:1}}>
<View style={{height:insets.top ,backgroundColor :"black"}}/>
<StatusBar barStyle="light-content"/>
<View style={{flex:1}}>
  <Text>My Text</Text>
</View>
</View>
)}
</SafeAreaConsumer>

Answer 8

请确保使用padding而不是margin. 这是我的代码，它在 iOS 中运行良好：

import { SafeAreaView } from 'react-native'
import { StatusBar } from 'expo-status-bar'
// ...
// ...
return <SafeAreaView style={{ paddingTop: height }}>
  {/* your content here */}
  <StatusBar style="light" />
</SafeAreaView>

Answer 9

稍微改变了jmurzy的解决方案，这个解决方案应该适用于 android 和 iOS，包括带有缺口的 iOS：

import React from 'react'
import { SafeAreaView, StatusBar, View } from 'react-native'
import { SafeAreaProvider, useSafeAreaInsets } from 'react-native-safe-area-context'

const App = () => {
    const isDarkMode = true
    return (
        <SafeAreaProvider>
            <CustomStatusBar
                barStyle={isDarkMode ? 'light-content' : 'dark-content'}
                backgroundColor={'red'}
            />
            <SafeAreaView style={{ flex: 1 }}>

                
            </SafeAreaView>
        </SafeAreaProvider>
    )
}

export default App

const CustomStatusBar = ({backgroundColor, ...props}) => {
    const { top } = useSafeAreaInsets()

    return (
        <View style={{ height: (StatusBar.currentHeight || top), backgroundColor }}>
            <SafeAreaView style={{ backgroundColor }}>
                <StatusBar translucent backgroundColor={backgroundColor} {...props} />
            </SafeAreaView>
        </View>
    )
}

Answer 10

如果你使用 React Navigation，那真的很简单！

只需设置headerStyle，另请参阅此处的文档。

就像是

<Stack.Navigator initialRouteName="Home">
  <Stack.Screen
    name="Home"
    component={HomeScreen}
    options={{
      title: 'my app',
      headerStyle: {
        backgroundColor: 'green',
      },
    }}
  />
</Stack.Navigator>

Answer 11

这适用于我的react-native-safe-area-context版本3.3.2

import { StatusBar } from "react-native"
import { SafeAreaProvider, SafeAreaView } from "react-native-safe-area-context"

const App = () => {

  const theme = ... get your theme

  return (
    <>
      <StatusBar
        backgroundColor={theme === "light" ? "#fff" : "#000"}
        barStyle={theme === "light" ? "dark-content" : "light-content"}
      />
      <SafeAreaProvider>
        <SafeAreaView
          style={{
            flex: 1,
            backgroundColor: theme === "light" ? "#fff" : "#000",
          }}
        >  

          // stuff goes here

        </SafeAreaView>
      </SafeAreaProvider>
    </>
  )
}

Answer 12

 render() {
        let { email, password, isLoading } = this.state
        return (
            <View style={{ flex: 1, }}>
                <StatusBar
                    translucent
                    barStyle="light-content"
                    //  backgroundColor="rgba(0, 0, 0, 0.251)"
                    backgroundColor='magenta'
                 />
            </View>
            )
        }

Answer 13

我能够更改 iOS 上状态栏的背景颜色，但更新 了组件的backgroundColor属性。SafeAreaView

<SafeAreaView style={{backgroundColor: 'blue'}}>
   // App Content
</SafeAreaView>
