Control 自定义控件
===
您可以通过此组件来实现自定义控件。同时你可以使用 Map 组件 widget 属性来更方便，设置自带默认控件。
``jsx`
import { Control, useControl } from '@uiw/react-baidu-map';
// 或者单独安装使用
import Control, { useControl } from '@uiw/react-baidu-map-control';

`jsx mdx:preview
import React, { useState, useRef } from 'react';
import { Map, Control, APILoader } from '@uiw/react-baidu-map';
const Example = () => {
const [count, setCount] = useState(0);
const map = useRef(null);
return (
onClick={() => {
const instanceMap = map.current.map
if (instanceMap) {
instanceMap.setZoom(instanceMap.getZoom() + 2);
}
}}
>
放大2级
onClick={() => {
const instanceMap = map.current.map
if (instanceMap) {
instanceMap.setZoom(instanceMap.getZoom() - 2);
}
}}
>
缩小2级
);
}
const Demo = () => (
);
export default Demo;
