Making GET and POST Requests from an iPhone Application - Clarification Needed

Question

I\'m following along with this useful looking answer to my question.

It seems to be working, but here are two questions I have:

1. How do I detect an HTTP

Answer 1

You will get the status code returned in the didReceiveResponse

-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{
    NSHTTPURLResponse *httpResponse;
    httpResponse = (NSHTTPURLResponse *)response;
    int statusCode = [httpResponse statusCode];
    //statusCode will be the http code returned like 201,500
 }

For stopping the connection, use a class-level variable for the connection. The best way to go about it would be create a wrapper which sends requests and receives response. Make your viewcontroller a delegate of this class and whenever the didReceiveResponse gives an error status code, call the appropriate method of the delegate and stop the connection.

Here's a good wrapper class example
