If you want to upload multiple images and you want to keep the parameter name same for all the images you do it as below :

NSDictionary *parameters = @{@"user_key": @"*****"};
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:queryStringss parameters:parameters constructingBodyWithBlock:^(id formData) {
    NSError *error;
    [formData appendPartWithFileData:imageData name:@"photo_file[0]" fileName:@"Picture44.png" mimeType:@"image/png"];
    [formData appendPartWithFileData:imageData1 name:@"photo_file[1]" fileName:@"Picture45.png" mimeType:@"image/png"];
} error:nil];

In this way the files would be sent as array to the server.
