Creating multiple NSURLConnections. How to identify which Async call

Question

I am intending to create 2 requests using NSURLConnection. When the server responds and calls connectionDidFinishLoading it passes in the connection as the parameter, but how d

Answer 1

Save both NSURLConnection objects as member variables of whatever delegate object you passed to connectionWithRequest:delegate:. Then you can just compare each of those to the NSURLConnection passed to connectionDidFinishLoading:, and respond appropriately:

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
    if (connection == firstConnection) {
        // do something
    }
    else if (connection == secondConnection) {
        // do something else
    }
}

Another slightly more object-oriented option would be to create two different delegate objects, each of which knows how to deal with each each type of connection. Then just pass the appropriate delegate when you create each connection. That way you don't need to check to see which connection you have, because each delegate will only receive connectionDidFinishLoading: for its own connection.
