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.

Solution 1

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);

Maybe it's not clear in the code, but the trick is to use StatusBar, which works for Android, and create a "fake" status bar (a View with backgroundColor) for IOS.

Solution 2

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.

Solution 3

you need to customize it.
StatusBar is not part of screen layout in ios else if you use SafeAreaView from reac-native

instead use react-native-safe-area-context and customize it.

see this snack.

Solution 4

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.

set iOS & Android statusbar backgroundColor in react-native

    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;

Solution 6

Add to root view. (Out of SafeAreaView if has)

{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
...

Solution 7

Please, make sure to use padding and not margin. This is my code and it works well in iOS:

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

Solution 8

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>

Slightly changed jmurzy's solution this one should work with android and iOS including iOS with notch:

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>
    )
}

If you are using React Navigation it is really easy!

Just set the headerStyle, see also documentation here.

Something like

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

Solution 11

This works for me with react-native-safe-area-context version 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>
    </>
  )
}

Solution 12

I was able to change the background color of status bar on iOS but updating the backgroundColor property of the SafeAreaView component.

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