cocoa http post request

hello i know this has been asked and answered many times but i cant seem to understand how it works (im new to iphone dev & objective c in general)

i am trying to make a create user for my app. i have a file create.php on my server that expects to get a _POST variable called id. after it is called it echos "DONE" for success and "EXIT" for failure.

i found some code and altered it (to the best of my knowledge) to fit my needs : 

NSMutableString *tmpurl = [NSMutableString stringWithString: @"http://mysite.com/"];
[tmpurl appendString:@"create.php"];
NSURL *url = [NSURL URLWithString:tmpurl];
NSString *uid = @"32478907348920437829078902347804930893741"; // should chenge for randome.
NSString *post = [NSString stringWithFormat:@"id=%@", uid];

NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];

now i don't know how to see what the page echos back or even if it has reached it.

any information would be appreciated and thank you in advance.

You are missing the NSURLConnection. Depending if you want to send this request synchronous or async, you may need to implement the NSURLConnectionDelegate methods.
