Managing multiple asynchronous NSURLConnection con

Question

I have a ton of repeating code in my class that looks like the following:

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

The problem with asynchronous requests is when you have various requests going off, and you have a delegate assigned to treat them all as one entity, a lot of branching and ugly code begins to formulate going:

What kind of data are we getting back? If it contains this, do that, else do other. It would be useful I think to be able to tag these asynchronous requests, kind of like you're able to tag views with IDs.

I was curious what strategy is most efficient for managing a class that handles multiple asynchronous requests.

I usually create an array of dictionaries. Each dictionary has a bit of identifying information, an NSMutableData object to store the response, and the connection itself. When a connection delegate method fires, I look up the connection's dictionary and handle it accordingly.
