i upload pictures, ranging few hundred 1000, using afnetwoking methods, there drawback, reads image data 1 time, memory up，for example:

nsoperationqueue *operationqueue = [[nsoperationqueue alloc]init]； [operationqueue setmaxconcurrentoperationcount:1];  (nsurl *fileurl in filestoupload) {       nsurlrequest *request = [[afhttprequestserializer serializer] multipartformrequestwithmethod:@"post"          urlstring:@"http://example.com/upload" parameters:nil         constructingbodywithblock:^(id<afmultipartformdata> formdata) {             [formdata appendpartwithfileurl:fileurl name:@"images[]" error:nil];        }];         afhttprequestoperation *operation = [[afhttprequestoperation alloc] initwithrequest:request];        [operationqueue addoperation:operation]; }
