iphone 开发 googleMap api

传入地址获取详细信息

https://maps.google.com/maps/api/geocode/json?address=chaoyango&sensor=true

传入经纬度获取地名信息

https://maps.googleapis.com/maps/api/geocode/json?latlng=39.988350,116.417152&sensor=true

传入起始经纬度(地名) 获取线路

http://maps.google.com/maps/api/directions/json?origin=39.988350,116.417152&destination=39.999350,116.417152&sensor= true

或者

https://maps.google.com/maps/api/directions/json?origin=罗马花园&destination=中关村& mode=driving&sensor=true

在线路中使用路标(从立水桥到 朝阳罗马花园但是要经过知春路和鸟巢)

https://maps.googleapis.com/maps/api/directions/json?origin=立水桥&destination=朝阳罗马花园&waypoints=知春路|鸟巢&sensor=true

google地图多地点线路查询

http://ditu.google.cn/maps?f=d&source=s_d&saddr=昌平&daddr=立水桥+to:知春路+to:天安门+to:西单+to:中关村&hl=zh-CN&geocode=china
