TileLayer 地图图层

此类表示一个地图图层，您可以向地图中添加自定义图层，官方原生实例：https://lbsyun.baidu.com/jsdemo.htm#g0_2。

import { TileLayer, useTileLayer } from '@uiw/react-baidu-map';
// 或者单独安装使用
import TileLayer, { useTileLayer } from '@uiw/react-baidu-map-tile-layer';

基本用法

`jsx mdx:preview import React from 'react'; import { useState, useRef } from 'react'; import { Map, APILoader, TileLayer } from '@uiw/react-baidu-map';

const Example = () => { const [show, setShow] = useState(true); return ( <> <button onClick={() => setShow(!show)}> {show ? '关闭' : '开启'} </button> <Map widget={['NavigationControl']} zoom={16} center={{ lng: 116.332782, lat: 40.007978 }} style={{ height: 350 }}> <TileLayer visiable={show} getTilesUrl={(tileCoord, zoom) => { const { x, y } = tileCoord; // 根据当前坐标，选取合适的瓦片图 return http://lbsyun.baidu.com/jsdemo/demo/tiles/${zoom}/tile${x}_${y}.png; }} /> </Map> </> ); }

const Demo = () => ( <div style={{ width: '100%' }}> <APILoader akay="eYpCTECSntZmw0WyoQ7zFpCRR9cpgHFG"> <Example /> </APILoader> );

export default Demo;

### 使用 hooks

`tileLayer`, `setTileLayer`, `visiable`, `setVisiable`

```jsx mdx:preview
import React from 'react';
import { useRef, useEffect, useState } from 'react';
import { Map, APILoader, Provider, useMap, useTileLayer } from '@uiw/react-baidu-map';

const Example = () => {
  const divElm = useRef(null);
  const [show, setShow] = useState(true);
  const { setContainer, map } = useMap({
    zoom: 16, center: { lng: 116.332782, lat: 40.007978 },
    widget: ['NavigationControl']
  });

  const { setVisiable } = useTileLayer({
    visiable: show,
    map, getTilesUrl: (tileCoord, zoom) => {
      const { x, y } = tileCoord;
      // 根据当前坐标，选取合适的瓦片图
      return `http://lbsyun.baidu.com/jsdemo/demo/tiles/${zoom}/tile${x}_${y}.png`;
    }
  });

  useEffect(() => {
    if (divElm.current && !map) {
      setContainer(divElm.current);
    }
  }, [map]);
  return (
    <>
      <button onClick={() => {
        setShow(!show)
        setVisiable(!show)
      }}>
        {show ? '关闭' : '开启'}
      </button>
      <div ref={divElm} style={{ height: '100%' }} />
    </>
  );
}

const Demo = () => (
  <div style={{ width: '100%', height: '300px' }}>
    <APILoader akay="eYpCTECSntZmw0WyoQ7zFpCRR9cpgHFG">
      <Provider>
        <Example />
      </Provider>
    </APILoader>
  </div>
);
export default Demo;
