最近有很多网友在问RN上怎么集成百度地图,我在之前两个项目中都有使用到react-native-baidu-map
,觉得其中的步骤稍微有点复杂,如果哪一步有点疏漏,就很容易报错,接下来我就从零新建一个项目,一步一步记录下我安装的过程,希望能帮助到大家~
成都React-Native交流群,进群给管理,先到先得哦
react-native-baidu-map github地址
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
添加依赖, react-native-baidu-map/ios/lib 下的全部 framwordk:
方法:
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:
