When using NSURLConnection, there are several methods to be watching… I understand that connection:didReceiveResponse: could potentially be fired several times during a connection.

At what point is it safe to start working with the received information? Within connectionDidFinishLoading:?

In my project, I am appending the received data in connection:didReceiveData: by setting:
// append the data
[receivedData appendData:data];

Then I’m actually doing stuff with the results within the connectionDidFinishLoading: … creating my NSDictionary with TouchJSON, looping through the data and changing my UI.

Am I doing it correctly?

    connectionDidFinishLoading is the correct place to start working with the received data.

    didReceiveData is the correct place to append the newly received data (not didReceiveResponse).

    didReceiveResponse is a good place to check HTTP status codes etc.
