react-native-baidu-map

 

1.新建一个RN项目：(BaiDuMapTest)

---

 

 

出现以下界面，就表示新建项目成功了

 

 

 

2.安装react-native-baidu-map（注意：一定要在项目根目录下进行安装）：

---

在终端输入：
npm install react-native-baidu-map --save

 

 

3.Xcode配置：

---

 

 

 

 

 

 

Build Phases->Link Binary With Libraries 加入 libRCTBaiduMap.a

 

 

 

Build Settings->Search Paths， Framework search paths 添加$(PROJECT_DIR)/../node_modules/react-native-baidu-map/ios/lib,Header search paths 添加 $(SRCROOT)/../node_modules/react-native-baidu-map/ios/RCTBaiduMap

然后继续添加：CoreLocation.framework和QuartzCore.framework、OpenGLES.framework、SystemConfiguration.framework、CoreGraphics.framework、Security.framework、libsqlite3.0.tbd（xcode7以前为 libsqlite3.0.dylib）、CoreTelephony.framework 、libstdc++.6.0.9.tbd（xcode7以前为libstdc++.6.0.9.dylib）
例如：

全部添加完后：

接下来添加 BaiduMapAPI_Map.framework/Resources/mapapi.bundle

4.AppDelegate.m init 初始化

---

#import "RCTBaiduMapViewManager.h"
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    ...
    [RCTBaiduMapViewManager initSDK:@"api key"];//这里的api key 一定要在官网和APP的Bundle identifier对应，否则地图会显示失败
    ...
}

5.build一下，看看是否配置成功

---

此时可能会报这个错误：

解决办法：

#import "RCTViewManager.h"
#import "RCTConvert+CoreLocation.h"

改成

#import <React/RCTViewManager.h>
#import <React/RCTConvert+CoreLocation.h>

如图:

然后就build success啦~

6.到此为止，配置已经完成，我们可以在RN来玩一玩百度地图~

这里我们就参照官网的Demo给大家展示一下：

index.ios.js:

/**
 * Sample React Native App
 * https://github.com/facebook/react-native
 * @flow
 */

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View
} from 'react-native';

import BaiduMapDemo from './BaiduMapDemo';

export default class BaiDuMapTest extends Component {
  render() {
    return (
      <BaiduMapDemo />
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
  instructions: {
    textAlign: 'center',
    color: '#333333',
    marginBottom: 5,
  },
});

AppRegistry.registerComponent('BaiDuMapTest', () => BaiDuMapTest);
