L'upload d'une image à l'aide de AFNetworking 3.0

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    [formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil];
} error:nil];

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

NSURLSessionUploadTask *uploadTask;
uploadTask = [manager
          uploadTaskWithStreamedRequest:request
          progress:^(NSProgress * _Nonnull uploadProgress) {
              //This is not called back on the main queue.
              //You are responsible for dispatching to the main queue for UI updates
              dispatch_async(dispatch_get_main_queue(), ^{
                  //Update the progress view
                  [progressView setProgress:uploadProgress.fractionCompleted];
              });
          }
          completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
              if (error) {
                  NSLog(@"Error: %@", error);
              } else {
                  NSLog(@"%@ %@", response, responseObject);
              }
          }];

[uploadTask resume];

Dans ce code http://example.com/upload est api où l'image va télécharger et file://path/to/image.jpg local, le chemin de l'image.
