multithreading - NSURLConnection in background Thread -

i want load (big) asynchronously in background thread (use nsoperation).

after many searches came across 2 options: first use with:

cfrunlooprun() 

which explain wonderful in link : http://www.russellj.co.uk/blog/2011/07/09/nsurlconnection-in-a-background-thread/

the second use with:

nsport* port = [nsport port]; nsrunloop* rl = [nsrunloop currentrunloop]; // runloop rl addport:port formode:nsdefaultrunloopmode]; 

which explain in link : http://www.cocoaintheshell.com/2011/04/nsurlconnection-synchronous-asynchronous/

i realy want use first option because elegant , readability. i'm afraid not understand differences between 2 approaches.

thanks help.

i'd recommend following built-in method if suits needs. it's easy use , reliable.
