问题描述

我看到 Apple 在 iOS5 中演示了新的模拟器功能，除了静态位置之外，他们还展示了在模拟器上运行的应用程序上模拟位置移动的能力.我已经使用 GPX 文件成功模拟了单个位置，但我找不到任何模拟运动的方法.

I've seen Apple demoing the new simulator features in iOS5, and apart from static locations, they showed off the ability to simulate location movement on an application running on the Simulator. I have successfully simulated single locations using GPX files, but I can't find any way of simulating movement.

这个功能是在最后一刻被放弃还是我遗漏了一些明显的东西?

Did this feature get dropped at the last minute or am I missing something obvious?

推荐答案

<wpt> type 支持 <time> 元素，可用于模拟运动.Xcode 只会遍历循环中的点列表.例如，在柏林市中心步行只需 4 分钟:

The <wpt> type supports a <time> element which can be used to simulate movement. Xcode will just go through the list of points in a loop. For example, here's a short 4 minute walk in the center of Berlin:
