}注意事项:
1. 代码实现的是跳转第三方路径规划功能, 要直接跳转导航界面, 请参考各自官方文档, 修改 URL 中相应字段
高德 URL 字段说明: https://lbs.amap.com/api/amap-mobile/guide/ios/ios-uri-information
腾讯 URL 字段说明: https://lbs.qq.com/uri_v1/index.html
百度 URL 字段说明: https://lbsyun.baidu.com/index.php?title=uri/api/ios
2.跳转苹果自带地图, 在驾车,步行,公交来回切换, 苹果地图会出现闪退
3.注意坐标转换, 后台数据坐标类型一般为 GPS 坐标, 高德地图使用的是火星坐标(GCJ02), 腾讯地图默认使用的也是火星坐标, 百度地图默认使用的是百度坐标.腾讯地图和百度地图都可以通过修改 URL 中 coord_type字段修改坐标类型.
