I have an upload form like this:

<form action="http://localhost/upload.php" method="post" enctype="multipart/form-data">
    <input type="file" id="upload" name="upload" />
</form>

and php code to proceed upload form:

isset($_FILES["upload"]) or die("Error");
// Path prepare stuff
if (move_uploaded_file($_FILES["upload"]["tmp_name"], $outputFile)) {
    // Other processing stuffs
}

In xcode, Im constructing the request like this:

NSMutableURLRequest* request = [[AFHTTPRequestSerializer serializer]
                                multipartFormRequestWithMethod:@"POST"
                                URLString:@"http://localhost/upload.php"
                                parameters:nil
                              constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {
                                    [formData appendPartWithFormData:data name:@"somefilename.ext"];
                                } error:nil];

But seem like i did it wrong way, right?

UPDATE

Im new to AFNetworking and I want to understand how it constructs multiplart/form-data post like above. It looks like the code lack of the input's name "upload", hence will not be able to pass the first line of php upload script. I read the document from AFNetworking's GitHub, but they say nothing about constructing a form data with NSData which is the case here.

マルチパートに関するAFNetworking docには、次を使用する必要があると記載されています。

[[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST"......

次にNSURLSessionUploadTask、resumeメソッドにを使用します（リンクの完全なコード）。

作業中のサーバーでこれを機能させることができませんでした。代わりに AFHTTPSessionManager を使用しました。

AFHTTPSessionManager *manager = [AFHTTPSessionManager alloc]initWithBaseURL: @"someURL..."];
// If you need to add few more headers, now is the time - if not you can skip this
[manager setRequestSerializer:[AFJSONRequestSerializer serializer]];
[[manager requestSerializer] setValue:@"your custom value"
                    forHTTPHeaderField:@"relevant key"];
// Setting basic auth - only if you need it
[[manager requestSerializer] setAuthorizationHeaderFieldWithUsername:@"username"
                                                             password:@"password"];


             [manager POST:@"appendedPath"
                parameters:params
 constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

                   [formData appendPartWithFileData:yourNSDataFile
                                               name:@"file"
                                           fileName:@"customFileName"
                                           // The server I was working on had no type but you can google for all the existing types
                                           mimeType:@""];

             }

                 progress:nil
                  success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

                                   if (responseObject != nil)
                                   {
                                       NSDictionary *jsonDictionary = responseObject;
                                   }
                               }

                   failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

                                     // Handle your error
                               }];
