react-native 將目標地址的經緯度傳給高德或者百度來實現從當前位置到目標地址的路線規劃。

IOS端

配置白名單 由于iOS的限制，iOS系統在9之后的版本中，如果開發者的app希望調起高德地圖，必須在自己app的設置中配置白名單。

配置方法：

1、找到您的Info.plist文件

2、在文件中添加key：LSApplicationQueriesSchemes，類型是Array，如果曾經添加過，無需再次添加。

3、Array中添加一個item，類型為String，值為iosamap。

添加完成后截圖如下:

            }
        }).catch(err => console.error('An error occurred', err));
    },


};
module.exports = MyUtil;

調用：

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