Question

I have a certain URL “http://dev.mycompany.com” and I need to send some data (in JSON format) to it and get the response.

I can’t find my way through the hugeload of documentation and related questions here on SO. I’ve managed to get the data (without sending any data) with NSURLConnection and it works good, the code I have so far is nearly the same as on https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/URLLoadingSystem/Tasks/UsingNSURLConnection.html and so I don’t see any point of posting the code I have.

I can’t append some string to my URL as the data I need to send is JSON data. I am sorry if I sound like a noob, but I have very little experience in Obj-C and server communication.

You should send them as parameter to a post NSUrlRequest

As following:

NSURL *aUrl = [NSURL URLWithString:@"http://dev.mycompany.com"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:aUrl
                                         cachePolicy:NSURLRequestUseProtocolCachePolicy
                                     timeoutInterval:60.0];
[request setHTTPMethod:@"POST"];
NSString *postString = @"yourVarialbes=yourvalues";
[request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];

NSURLConnection *connection= [[NSURLConnection alloc] initWithRequest:request 
                                                             delegate:self];
[connection start];
