近期 TODO:

Android

• 完善坐标转换
• 添加一些常用的方法

iOS

• 完善坐标标转换
• 完善 Cluster（点聚合）
• 添加一些常用的方法

Marker icon 的实现参考了 https://github.com/react-native-community/react-native-maps 的相关代码。

Dev & Test 开发和测试说明

react-native doesn't support symlinks. see https://stackoverflow.com/questions/44061155/react-native-npm-link-local-dependency-unable-to-resolve-module. Can't install local package by using npm link.

react-native 不支持软链，参考： https://stackoverflow.com/questions/44061155/react-native-npm-link-local-dependency-unable-to-resolve-module 所以不能使用 npm link 的方式安装本地的包

Environments 环境要求

1.JS

• node: 12+
• react-native: 0.50.+ 2.Android
• Android SDK: api 28+
• gradle: 4.10.1
• Android Studio: 3.1.3+

3.iOS

初始化

Android

AndroidManifest.xml 设置

必要的权限

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

application 下添加名为 com.baidu.lbsapi.API_KEY 的 meta，如

<meta-data
        android:name="com.baidu.lbsapi.API_KEY"
        android:value="uDRdqQMGQeoPGn5CwMmIYicdUIVv1YST" />

iOS

使用 BaiduMapManager.initSDK 方法设置 api key，如

import { BaiduMapManager } from 'react-native-baidu-map'
BaiduMapManager.initSDK('sIMQlfmOXhQmPLF1QMh4aBp8zZO9Lb2A');
