如何在 React Native 中设置 iOS 状态栏背景颜色? [英] How to set iOS status bar background color in React Native?

问题描述

在 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 ?

解决方案

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, {成分，来自'反应';进口 {应用注册，样式表，看法，状态栏，平台，安全区域视图来自'反应原生';const MyStatusBar = ({backgroundColor, ...props}) =>(<视图样式={[styles.statusBar, { backgroundColor }]}><SafeAreaView><StatusBar 半透明 backgroundColor={backgroundColor} {...props}/></SafeAreaView></查看>);类 DarkTheme 扩展组件 {使成为() {返回 (<查看样式={styles.container}><MyStatusBar backgroundColor="#5E8D48";barStyle =光含量"；/><视图样式={styles.appBar}/><视图样式={styles.content}/></查看>);}}const STATUSBAR_HEIGHT = StatusBar.currentHeight;const APPBAR_HEIGHT = Platform.OS === 'ios' ?44:56；const 样式 = StyleSheet.create({容器: {弹性:1，},状态栏: {高度:STATUSBAR_HEIGHT，},应用栏:{背景颜色:'#79B45D'，高度:APPBAR_HEIGHT，},内容: {弹性:1，背景颜色:'#33373B'，},});AppRegistry.registerComponent('App', () => DarkTheme);

Is there a single place in the react native iOS native code that I could modify to set iOS statusbar backgroundColor? RCTRootView.m ?

The react native StatusBar component only support backgroundColor for Android only.

The iOS operating system seems to allow setting status bar backgroundColor

My goal is to have a darker status bar color.

解决方案

iOS doesn't have a concept of a status bar bg. Here's how you'd achieve this in a cross-platform way:

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);
