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.
