因为将backgroundColor道具应用于StatusBar组件未在IOS上应用。我需要设置SafeAreaView的背景色以获得我想要的效果,它可以正常工作,但在iPhone X上,它在屏幕底部将具有相同的颜色。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,但是在Android平台上可以(https://facebook.github.io/react-native/docs/statusbar#backgroundcolor)。我为您解决了问题。您可以安全使用它
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;

对iPhone X的支持
除了 @sdkcy 的答案外,对于 iPhone X ,STATUS_BAR_HEIGHT不能为20。
我通过安装以下库解决了该问题:
https://www.npmjs.com/package/react-native-status-bar-height
安装
npm install --save react-native-status-bar-height
导入
import { getStatusBarHeight } from 'react-native-status-bar-height';
并像这样更新STATUS_BAR_HEIGHT:
const STATUS_BAR_HEIGHT = Platform.OS === 'ios' ? getStatusBarHeight() : 0;
最后,我还将Android的高度更改为0,因为它会影响NavigationBar的高度,但是如果对您来说效果很好,您可以将其保持不变。
希望这会有所帮助。

iPhone X使用 44pt 高状态栏
const STATUS_BAR_HEIGHT = Platform.OS ==='ios'吗? 44:StatusBar.currentHeight;
