Thanks for posting - I might try delegates myself now you've done all the hard work ;)

I did finally get a round TUIT and come to grips with delegates.

See the Wiki example for NSURLConnection,  Retrieving data asynchronously using a custom delegate_object.

Late to the party and probably just in time to ignore the deprecated NSURLConnection and use its replacement NSURLSession - see the Wiki example Retrieving data using system-provided delegates. The NSURLSession Retrieving data using a custom delegate example is next on my ToDo list.
