detect geo-coords of other users

[m_kaminsky@yahoo.com]

Hey guys, general question..

How can users detect coords of other users currently using same app?

Not concerned so much with a requirement to login..
just want to allow for users to set name maybe..

Currently, looking for a working chat example project..
Figure this would be good start-point...

Just want a very basic, device info exchange...

Can this be done in a straightforward manner?!?


Thanks in advance

I do this by uploading every user's info (location included) to the server every certain time. This way, each user may have somewhat accurate data about other user's location. If this is what you want you must set up your own server and upload each user's info to it.

PD. I know nothing about the server side implementation.

Thanks! Wanted to share some additional thoughts..let me know if you
can add any insight..

...so a central server, separate from the participating phones..(I guess having the phones communicate individually with the others doesn't make sense)..

...posting of user info...then reading of info...that would be php I'm guessing...looking for a simple option..

There are a couple examples I'm familiar with that do some of this (reading of web text, etc)...if you can point-out a particular one...like a working chat example, please let me know!

Many thanks,

Mark

Yes, you need a central server. You can use whatever protocol you want. AIM used to have a JSON-based interface that was publicly available, and even provided Objective C code you could use to create an AIM chat client. I heard rumors that they weren't taking on new client applications any more though.

Writing an AIM chat client that included location information as "sideband" data was one of the first things I did in iOS. I can't share that code however. Sorry.
