How to set iOS status bar background color in Reac

问题:

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.

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,
} from 'react-native';

const MyStatusBar = ({backgroundColor, ...props}) => (
  <View style={[styles.statusBar, { backgroundColor }]}>
    <StatusBar translucent backgroundColor={backgroundColor} {...props} />
  </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 = Platform.OS === 'ios' ? 20 : 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);

Add import { StatusBar } from 'react-native'; to the top of your app.js and then add StatusBar.setBarStyle('light-content', true); as the first line in your render() to change the status bar text/icons to white.

The other color options are 'default' and 'dark-content'.

Refer to https://facebook.github.io/react-native/docs/statusbar.html for further info.

Other than that: no, you would have to follow the link you provided.

If you are using react-native-navigation, you need to:

1-) Add this to your info.plist file: <key>UIViewControllerBasedStatusBarAppearance</key> <string>YES</string>

2-) At first line of your render() function, eg: render(){ this.props.navigator.setStyle({ statusBarTextColorScheme: 'light' }); return ( <Login navigator={this.props.navigator}></Login> ); }

This example will transform your status bar to light text/buttons/icons color.
