React Native IOS Status Bar background

问题

Since Applying the backgroundColor props to StatusBar component doesn't get applied On IOS. I need to set the background colour of SafeAreaView to get the effect i want, it works fine but on iPhone X it will have that same colour at the bottom of the screen. How can I solve this issue?

回答1:

React-Native does not support background color change of StatusBar on iOS platform but on Android platform, it's ok (https://facebook.github.io/react-native/docs/statusbar#backgroundcolor). I wrote a work around for your problem. You can use it safely

import React, {Component} from "react";
import {StyleSheet, StatusBar, View, Platform} from "react-native";

const STATUS_BAR_HEIGHT = Platform.OS === 'ios' ? 20 : StatusBar.currentHeight;

function StatusBarPlaceHolder() {
    return (
        <View style={{
            width: "100%",
            height: STATUS_BAR_HEIGHT,
            backgroundColor: "blue"
        }}>
            <StatusBar
                barStyle="light-content"
            />
        </View>
    );
}

class App extends Component {
    render() {
        return (
            <View style={{flex: 1}}>
                <StatusBarPlaceHolder/>
                ...YourContent
            </View>
        );
    }
}

export default App;

For SafeAreaView:

import React, {Component} from "react";
import {StyleSheet, StatusBar, View, Platform} from "react-native";
import SafeAreaView from "react-native-safe-area-view";
//You can also use react-navigation package for SafeAreaView with forceInset.

const STATUS_BAR_HEIGHT = Platform.OS === 'ios' ? 20 : StatusBar.currentHeight;

function StatusBarPlaceHolder() {
    return (
        <View style={{
            width: "100%",
            height: STATUS_BAR_HEIGHT,
            backgroundColor: "blue"
        }}>
            <StatusBar
                barStyle="light-content"
            />
        </View>
    );
}

class App extends Component {
    render() {
        return (
            <SafeAreaView style={{flex:1}}
                forceInset={{top: 'never'}}>
                <StatusBarPlaceHolder/>
                ...YourContent
            </SafeAreaView>
        );
    }
}

export default App;
