Essayez AFNetworking avec le code ci-dessous,

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"upload_url" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { 

    [formData appendPartWithFileData:data name:@"upload_file_name" fileName:@"somefilename.jpg" mimeType:@"mime_type_of_file"] // you file to upload 

    } 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];
