此处给出了最简单示例，创建标记

```tsx
import React, { useState } from 'react';
import { Map, Marker, InfoWindow } from 'react-amap-v2';
import Mock from 'mockjs';

import Paper from '@material-ui/core/Paper';
import FormControlLabel from '@material-ui/core/FormControlLabel';
import Button from '@material-ui/core/Button';
import Switch from '@material-ui/core/Switch';
import Select from '@material-ui/core/Select';
import MenuItem from '@material-ui/core/MenuItem';

const anchors = [
  'top-left',
  'top-center',
  'top-right',
  'middle-left',
  'center',
  'middle-right',
  'bottom-left',
  'bottom-center',
  'bottom-right',
];

export default () => {
  const [visible, setVisible] = useState(true);
  const [pos, setPos] = useState([121.436938, 31.180024]);
  const [anchor, setAnchor] = useState('bottom-center');

  return (
    <>
      <Paper style={{ marginBottom: 20, padding: 20 }} color="text.primary">
        <FormControlLabel
          control={

        >
          随机位置
        </Button>
      </Paper>
      <Map center={pos}>
        <Marker

          events={{
            click: () => {

            open: () => {
              setVisible(true);
            },
          }}
        >
          <div
            onClick={() => {
              console.log('1');
            }}
          >
            <span>信息窗体 {pos}</span>
          </div>
        </InfoWindow>
      </Map>
    </>
