i have 1 class processes requests composing framework, https://github.com/ivasic/restframework . want able execute requests requests , return responses individually caller. stands if have more 2 request, result of second 1 domes not come through, seems happen @ same time. what solution this? you have caller pass block "one class handles requests." caller block can response. // inside caller class. oneclassthathandlesrequests *ws = [oneclassthathandlesrequest sharedinstance]; [ws getfromurl: @"http://webservice.com/people/jack" completionblock: ^(urlrequest *request , urlhttpresponse *response, nsdata *data) { // make sure we got 200 code back. // change data json if i'm getting json back. }]; now oneclassthathandlesrequests knows how pass information call without oneclassthathandlesrequests needing know called. you use delegate pattern, blocks case makes more sense me
