原生部分
Android配置
react-native link react-native-baidu-map
配置AndroidManifest.xml文件
1.在<application>中加入如下代码配置开发密钥(AK)
<application>
<meta-data
android:name="com.baidu.lbsapi.API_KEY"
android:value="开发者 key" />
</application>2.在<application/>外部添加如下权限声明:
//获取设备网络状态,禁用后无法获取网络状态 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> //网络权限,当禁用后,无法进行检索等相关业务 <uses-permission android:name="android.permission.INTERNET" /> //读取设备硬件信息,统计数据 <uses-permission android:name="android.permission.READ_PHONE_STATE" /> //读取系统信息,包含系统版本等信息,用作统计 <uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" /> //获取设备的网络状态,鉴权所需网络代理 <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> //允许sd卡写权限,需写入地图数据,禁用后无法显示地图 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> //这个权限用于进行网络定位 <uses-permission android:name="android.permission.WRITE_SETTINGS" /> //这个权限用于访问GPS定位 <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> //获取统计数据 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> //使用步行AR导航,配置Camera权限 <uses-permission android:name="android.permission.CAMERA" /> //程序在手机屏幕关闭后后台进程仍然运行 <uses-permission android:name="android.permission.WAKE_LOCK" />
IOS配置
使用pod,Podfile文件中添加
pod 'React', :path => '../node_modules/react-native', :subspecs => [
'Core',
'CxxBridge',
'DevSupport',
'RCTText',
'RCTNetwork',
'RCTWebSocket',
'RCTAnimation'
]
pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'
pod 'DoubleConversion', :podspec => '../node_modules/react-native/third-party-podspecs/DoubleConversion.podspec'
pod 'glog', :podspec => '../node_modules/react-native/third-party-podspecs/glog.podspec'
pod 'Folly', :podspec => '../node_modules/react-native/third-party-podspecs/Folly.podspec'
pod 'react-native-baidu-map', :podspec => '../node_modules/react-native-baidu-map/ios/react-native-baidu-map.podspec'注意!!!:AppDelegate.m init 初始化,使用如下代码,可以解决RCTBaiduMapViewManager.h文件找不到的问题
#import <react-native-baidu-map/BaiduMapViewManager.h>
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
// 地图 ak 注册
[BaiduMapViewManager initSDK:@""];
...
}使用
导入
import { MapView, MapTypes, Geolocation, Overlay } from 'react-native-baidu-map'
const { Marker } = Overlay;
<MapView
width={deviceWidth}
height={200}
zoom={18}
trafficEnabled={true}
zoomControlsVisible={true}
mapType={MapTypes.SATELLITE}
center={{ longitude: 116.465175, latitude: 39.938522 }}
>
<Marker
title='中心'
location={{longitude: 116.465175, latitude: 39.938522}}
/>
</MapView>效果,上图
