现在已经有一段时间我对将GPX文件添加到
Iphone / iPad项目有疑问.

GPX文件包含什么,以及它如何帮助我们在模拟器上运行应用程序. 最佳答案 首先来看看
this wiki site.

GPX, or GPS eXchange Format is an XML schema designed as a common GPS data format for software applications.
It can be used to describe waypoints, tracks, and routes. The format is open and can be used without the need to pay license fees. Its tags store location, elevation, and time and can in this way be used to interchange data between GPS devices and software packages. Such computer programs allow users, for example, to view their tracks, project their tracks on satellite images or other maps, annotate maps, and tag photographs with the geolocation in the Exif metadata.
