SafeAreaView

SafeAreaView は、デバイスのセーフエリア領域

The purpose of SafeAreaView is to render content within the safe area boundaries of a device. It is currently only applicable to iOS devices with iOS version 11 or later.

SafeAreaView renders nested content and automatically applies padding to reflect the portion of the view that is not covered by navigation bars, tab bars, toolbars, and other ancestor views. Moreover, and most importantly, Safe Area's paddings reflect the physical limitation of the screen, such as rounded corners or camera notches (i.e. the sensor housing area on iPhone X).

Example

To use, wrap your top level view with a SafeAreaView with a flex: 1 style applied to it. You may also want to use a background color that matches your application's design.

import React from 'react';
import { StyleSheet, Text, SafeAreaView } from 'react-native';

export default function App() {
  return (
    <SafeAreaView style={styles.container}>
      <Text>Page content</Text>
    </SafeAreaView>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
  },
});
