IOS uses afnetworking to upload single, multiple photos to the background

We said that the first way to upload pictures is to transfer the pictures to the image stream to upload; Today we are going to introduce another approach. is to use the method of afnetworking in the use of URLs to upload the way. Concrete backstage how to receive I don't know clearly.
The old words do not say more directly on the code.

Afhttprequestoperationmanager *manager = [Afhttprequestoperationmanager manager];//instantiation AFN
Afjsonresponseserializer *response = [Afjsonresponseserializer serializer];
JSON transfer Mode
Response.removeskeyswithnullvalues = YES;
Manager.responseserializer = response;

Manager.requestserializer = [Afhttprequestserializer serializer];

[Manager Post:url Parameters:
Nsdictionary
Constructingbodywithblock:
(void (^) (id<afmultipartformdata>))
success:^ (afhttprequestoperation * _nonnull operation, id _nonnull responseobject) {

Success (Responseobject);
} failure:^ (Afhttprequestoperation * _nonnull operation, Nserror * _nonnull error) {
Failure (error);
}];

where (void (^) (id<afmultipartformdata>)) is uploaded to the image

The picture can be a single sheet or multiple sheets.
Leaflet: [FormData appendpartwithfiledata:uiimagepngrepresentation (image) name:@ "Images" filename:@ "Name.png" mimetype:@ "Image/png"];
Multiple: This method to do a loop to arrange the picture into a queue;
Note: The Namec parameter must be the same as the background, otherwise the background will not receive
