iOS development-parse JSON and XML data using third-party library afnetworking

Using the third-party library afnetworking to parse the JSON and MXL data requested by the network has many convenient places.

The third party libraries: https://github.com/AFNetworking/AFNetworking

2. How to request XML in the Get mode

It also uses a third-party library provided by Google Gdata to parse the XML file, github:https://github.com/graetzer/gdataxml-html

//Error: 3840---means that the data for the server segment is not strictly written in XML format//XML parsing- (void) xmlgetrequest{Afhttprequestoperationmanager*manager =[Afhttprequestoperationmanager Manager]; //manager.responseSerializer.acceptableContentTypes = [Nsset setwithobject:@ "Text/xml"]; //generate a serialized object of your own response, without using the system-given wayManager.responseserializer =[[Afhttpresponseserializer alloc] init]; [Manager get:kxmlurlstring Parameters:nil success:^ (Afhttprequestoperation *operation,IDresponseobject) {gdataxmldocument*doc=[[Gdataxmldocument alloc] Initwithdata:responseobject encoding:nsutf8stringencoding Error:nil]; NSString*path =@"/doc/focus/frame/title"; Nsarray*titles=[Doc Nodesforxpath:path Error:nil];  for(Gdataxmlelement *titleinchtitles) {NSLog (@"%@", Title.stringvalue); }        //NSLog (@ "requestobject =%@", responseobject);} failure:^ (Afhttprequestoperation *operation,nserror *error) {NSLog (@"error =%@", error); }];}

3. How to request a JSON post

//POST request data operation JSON data- (void) Jsonpostrequest: (Nsdictionary *) dict{//single-instance objectsAfhttprequestoperationmanager *manager =[Afhttprequestoperationmanager Manager]; Manager.responseSerializer.acceptableContentTypes= [Nsset setwithobject:@"Application/json"]; [Manager post:kjsonposturlstring parameters:dict success:^ (Afhttprequestoperation *operation,IDresponseobject) {NSLog (@"Responseobject =%@", Responseobject); } Failure:^ (Afhttprequestoperation *operation,nserror *error) {NSLog (@"error =%@", error); }];}

4. How to post the XML request

1 //Post method request XML data2- (void) Xmlpostrequest: (Nsdictionary *) Dict3 {4Afhttprequestoperationmanager *manager =[Afhttprequestoperationmanager manager];5     //manager.responseSerializer.acceptableContentTypes = [Nsset setwithobject:@ "Text/xml"];6     //parse XML using the object you created7Manager.responseserializer =[Afhttpresponseserializer alloc];8[Manager post:kxmlposturlstring Parameters:dict success:^ (afhttprequestoperation *operation,IDresponseobject) {9         TenNSLog (@"Responseobject =%@", responseobject); One      A} failure:^ (afhttprequestoperation *operation,nserror *error) { -          -NSLog (@"error =%@", error); the      -     }]; -}
