Question

I’m developing an iPad application in which a user fills in their details and presses a submit button, which sends the information to a specific Web server (which will later be viewed by a person)

As far as protocols for Web services are concerned, I know JSON and XML. Are there any other protocols that I should be looking into? (or perhaps by a different method completely)

I’d be very grateful for any help.

If you just want to send text info to server you can try this code:

NSString *textdata = [YourTextField text];
NSString *anotherTextdata = [YourAnotherTextField text];

NSString *urlpath;
urlpath = [@"http://yoursiteapiurl.com/" stringByAppendingString:@"yourserverfile.php?textdata="];
urlpath = [urlpath stringByAppendingString:textdata];
urlpath = [urlpath stringByAppendingString:@"&anotherTextData="];
urlpath = [urlpath stringByAppendingString:anotherTextdata];

NSURL *url=[[NSURL alloc] initWithString:[urlpath stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

NSString *a = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil];

The variable a will have the response of this URL. The server could send XML and then you can parse that XML using any XML parsing technique.
