iOS的API，用于实时交通数据（如geoloqi和Waze的） [英] iOS api for real time traffic data (like geoloqi and Waze)
问题描述
我已经访问过一些服务API的网站，但无法找到我所期待的。我的问题是更多的目的是使用什么样的资源，而不是它应该如何准确完成。
I have been visiting some services api website but can't find what I am looking for. My question is more aimed at what resources to use rather than how exactly it should be done.
我的iPhone应用程序的要求是要能够跟踪其附近的用户，上下班，并找到他们在地图上。附加要求也许他们发短信，打电话给他们，与他们视频会议等。在一个较高的水平，这将转化为类似
My iphone app requirement is to be able to track users that are nearby, are commuting and locate them on map. Additional requirement maybe texting them, call them, have video session with them etc. On a high level, this will convert to something like
- 获得基于经度和纬度的用户详细信息
- 了解，如果他们注册服务的用户订阅
- 发送邮件到用户/用户
- 使用iphone手机API或专门的应用程序会调用用户
- 视频通话
Waze的是其中之一。虽然它是开源的，有在一个如何使用它作为后端的实时交通数据相当少的文件。
Waze is one of them. While it is open source, there is quite less documentation on how one can use it as backend for real time traffic data.
再有就是这个 Geoloqi 这是支付，但iOS的SDK以及丰富的API。但是我无法找到当我抬头向上面列出我的要求是对我有用的部分。我相信的是，一定有很多的应用程序已经依赖于这样一个有用的服务。如果其中任何一个是开源/教程，这将是最有用的资源，我要geoloqi的可行性。 Geoloqi还收费用户使用他们的API，所以它也非常重要，我知道什么都在什么价位的功能。
Then there is this Geoloqi which is paid, but has iOS SDK as well as rich api. However I cannot find sections that are useful to me when I look up to my requirements listed above. What I believe is that there must be many apps already relying on such a useful service. If any of them are open source / tutorials, it would be most useful resource for me for feasibility of geoloqi. Geoloqi also charges users for using their api, so it is also important for me to know what features come at what price .
推荐答案
有关的数据/信息的兴趣和功能水平，你应该让自己的应用程序，我不认为你需要这些API。
For the level of data/information your interested in, and the functionality, you should just make your own app, I dont think you need those APIs.
您可以找到并送谁在使用你的应用程序到服务器的人的坐标。然后，你需要确定它们之间的距离，看看他们是在谈论的区域，或任何其他你在上面列出的功能。
You can find and send the coordinates of the people who are using your app to your server. Then you need to determine the distance between them, to see if they are in the zone of talking, or whatever other functionality you have listed above.
要确定两个人之间的距离，这个答案应该是有帮助的：<一href=\"http://stackoverflow.com/questions/365826/calculate-distance-between-2-gps-coordinates\">Calculate 2 GPS之间的距离坐标
To determine the distance between two people, This answer should be helpful: Calculate distance between 2 GPS coordinates
