当点击图标组件时，在iOS和Android中以原生组件样式显示选取器

import React, { useState } from 'react';
import { View, TouchableOpacity, Text, Picker } from 'react-native';

const MyComponent = () => {
  const [selectedValue, setSelectedValue] = useState('');

  const handleIconClick = () => {
    // 在这里处理图标点击事件
    // 显示选取器
  };

  return (
    <View>
      <TouchableOpacity onPress={handleIconClick}>
        {/* 这里放置图标组件 */}
        <Text>点击图标</Text>
      </TouchableOpacity>
      <Picker
        selectedValue={selectedValue}
        onValueChange={(itemValue) => setSelectedValue(itemValue)}
      >
        <Picker.Item label="选项1" value="option1" />
        <Picker.Item label="选项2" value="option2" />
        <Picker.Item label="选项3" value="option3" />
      </Picker>
    </View>
  );
};

export default MyComponent;
