Simple http post example in Objective-C?

Question

I have a php webpage that requires a login (userid & password). I have the user enter the information into the app just fine.. but I need an example on how to do a POST request to a website. The apple example on the support site is rather complicated showing a picture upload.. mine should be simpler.. I just want to post 2 lines of text.. Anyone have any good examples?

This is what I recently used, and it worked fine for me:

NSString *post = @"key1=val1&key2=val2"; NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];  NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];  NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:@"http://www.nowhere.com/sendFormHere.php"]]; [request setHTTPMethod:@"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData];
