Dynamic access to host IP when registering for login

When we want to afnetworking get registered login URL, sometimes found that host provides a dynamic IP, each time the URL is not the same, specifically encapsulated a method of acquiring IP

This method is encapsulated in the afnetworking

The tagged parts of the figure need IP URLs to obtain IP, which is typically provided by the server

After the file import, you can use the following method to register or log in to parse

-  (void) requestweb{        //parameters      nsdictionary *params = @{@ "user_id":  @ "0",                               @ "is_traditional":  @ "0",                               @ "page":  @ "1",                              @ "PageRecord":  @ "3",                              @ "Phonetype":  @ "1",};     [afhttprequestoperationmanager getrequest:url_cookbook parameters:params success:^ (AFHTTPRequestOperation * Operation, id responseobject)  {                //   the data returned by the print server         nslog (@ " %@ ", operation.responseobject);         } failure:^ ( Afhttprequestoperation *operation, nserror *error)  {//         nslog (@ "%@", error);     }];}
