React Native IOS状态栏背景

Question

由于将backgroundColor props应用于StatusBar组件,因此未在IOS上应用.我需要设置SafeAreaView的背景颜色以获得我想要的效果,它工作正常但在iPhone X上它将在屏幕底部具有相同的颜色.我该如何解决这个问题？

React-Native在iOS平台上不支持StatusBar的背景颜色更改，但在Android平台上是可以的（https://facebook.github.io/react-native/docs/statusbar#backgroundcolor）。我为您解决了问题。您可以安全使用

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;

对于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;
