I am switching my app from ASIHTTPRequest to AFNetworking. In ASIHTTPRequest there is the ASINetworkQueue class, which lets me queue up a series of HTTP requests, and when the queue is completed, call a method. How can I do this with AFNetworking and NSOperationQueue? I can't seem to find out how to add a completion method or block to NSOperationQueue.
