使用AFNetworking在单个请求中上传多个图像

我想在一个请求中上传多个图像,我设法在发送单个图像数据时使其工作。这是我发送单个图像数据的代码:

AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseUrl: my_url ];

NSMutableRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:nil
parameters:nil constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
    [formData appendPartWithFileData: my_imageData name:@"image" fileName: @"myImage.jpg" mimeType:@"image/jpeg"];
}];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest: request];

[operation start];

在服务器端,我使用Spring MVC。这是将接收包含多个图像的请求的Web服务/端点:

@RequestMapping(value="/test-multiple-upload/{collateralid}", method = RequestMethod.POST)
public @ResponseBody String multipartfilesUpload(
        @PathVariable("collateralid") Long collId,
        @RequestParam("images[]") CommonsMultipartFile[] images) {

    //proccess the image data. save to local or to DB


    return "uploaded successful";
}

我的问题是如何使用具有多个图像的AFNetworking进行multipartForm请求。
