推荐：跨平台React Native组件——@expo/react-native-action-sheet

import React from 'react';
import { View, Button, StyleSheet } from 'react-native';
import * as ActionSheet from '@expo/react-native-action-sheet';
 
export default class App extends React.Component {
  showActionSheet = () => {
    ActionSheet.showActionSheetWithOptions({
      options: ['选项一', '选项二', '取消'],
      cancelButtonIndex: 2,
      destructiveButtonIndex: 0,
    }, buttonIndex => {
      console.log('按下了按钮', buttonIndex);
    });
  }
 
  render() {
    return (
      <View style={styles.container}>
        <Button onPress={this.showActionSheet} title="显示动作表" />
      </View>
    );
  }
}
 
const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
});

这段代码演示了如何在React Native应用中使用@expo/react-native-action-sheet模块来创建一个简单的动作表（ActionSheet）。当用户点击按钮时，会触发showActionSheet函数，该函数调用ActionSheet.showActionSheetWithOptions方法来显示动作表，并且定义了选项和按钮的行为。
