    <p>You've asked quite a few questions so I'll try my best to answer them all:</p> <p>First, you need to be a bit clearer, what type of server are you talking about? Email server, web server, lolcat server, it depends.</p> <p>At the basic level, the iphone communicates over the internet. The internet uses Internet Protocol, and there are two standard protocols built atop of IP: Transmission Control Protocol, and User Datagram Protocol. Each has it's own uses and functions.</p> <p>TCP/IP and UDP/IP make up the backbone of internet communication.</p> <p>A more specific application protocol is built atop of these two internet protocols, with a specific format to a given application. For example, HTTP is the standard protocol for transferring HTML and other Web information between a web server to a web browser client, over TCP.</p> <p>So, your iPhone would use whatever protocol is required to commuincate with the server. For more common server communication, the iOS SDK provides methods to construct messages (for example if you wish to make an HTTP request to a web server, you can use <code>initWithContentsOfURL</code> to send a GET request).</p> <p>If you built a custom server, then you will need construct the required message protocol on the iphone, and send it to the server, using either TCP or UDP (whatever your custom server expects).</p>

    1. COThank you Alan! As for your questions, is it possible to use an email server on a app that doesn't sends email? (but rather sends data). Or is it possible to use a web server on a app that doesn't sends web data but email instead? Right now I don't even know what kind of server I should use for my iphone app... Also regarding how HTTP request would work, is it like is you use that api, initWithContentsOfURL, for example, http://someurl.com/somephp.php and then get a information, suppose there are two iphones that both calls that url, then how does the server know which iphone is it?

    2. COWell you wouldn't use a server on an app (a server handles client connections and handles service requests from clients--your app would likely be a client, not a server). And in general if you have a web server, it needs to handle web data, otherwise it's not a webserver, but just a server of some type. THe type of requests a server handles dictates it's type. Re: Web requests, if you need your server to know which iphone, you must pass along that information in the request. You can use query strings: `someurl.com/somephp.php?id=davids_iphone` or pass as part of the HTTP auth headers

    3. COBefore I get ahead of myself, ask, why does your server need to know what iphone is requesting the page? Who is requesting a resource is typically handled by "authentication" and there are a number of ways to go about authenticating a web session.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
