iOS Internet Interaction

[Blakeasd]

Hello,

I am curious about how some of the web interaction on iOS apps work. Let's say there is an app where you post a string of text and the text is tagged by location. Then another person on a different device searches for the name of that city and views the string of text posted by the other iOS device. Could someone explain what this is called or maybe even how this works? I'm not interested in building an app like this, but rather curious about the technology itself.

Such functionality is normally achieved through what is known as web services with a centralized server controlling the database of information to be shared. A client will send information to the server, through a web service request, to store some new info. Other clients will then, through a different web service request, retrieve certain kinds of info. If you would like to discuss more specifics, please indicate which areas on which you would like us to elaborate.
