亲测可行...
react-native 将目标地址的经纬度传给高德或者百度来实现从当前位置到目标地址的路线规划。
IOS端
配置白名单 由于iOS的限制，iOS系统在9之后的版本中，如果开发者的app希望调起高德地图，必须在自己app的设置中配置白名单。
配置方法：
1、找到您的Info.plist文件
2、在文件中添加key：LSApplicationQueriesSchemes，类型是Array，如果曾经添加过，无需再次添加。
3、Array中添加一个item，类型为String，值为iosamap。
添加完成后截图如下:

调用：
MyUtil.turn2MapApp(longitude, latitude, 'gaode');
