Question

I want to make an iPhone app that sends some data to a PHP web site, I know it can be done with a web service, but how? Can be done in realtime? If I got several iPhones how can I make my app?

Answer 1

 NSString *content = @"message=Message&user=21";

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://www.example.com/form.php"]];//The address of the website page
[urlRequest setHTTPMethod:@"POST"]; //Method GET/POST. POST is recommended
[urlRequest setHTTPBody:[content dataUsingEncoding:NSISOLatin1StringEncoding]];


// generates an autoreleased NSURLConnection
[NSURLConnection connectionWithRequest:request delegate:self];
