avos如何存储查询多张图片

Question

NSData *data;
        AVFile *imageFile;
        if (UIImagePNGRepresentation(image) == nil)
        {
            data = UIImageJPEGRepresentation(image, 1.0);
            imageFile = [AVFile fileWithName:@"image.jpg" data:data];
        }

        else

        {
            data = UIImagePNGRepresentation(image);
            imageFile = [AVFile fileWithName:@"image.png" data:data];
        }

        [imageFileCollection addObject:imageFile];
    }
    [testPost addObjectsFromArray:imageFileCollection forKey:@"testImageArray"];

代码如上，在后台看到testimagearray中显示null；求告知存储查询啊

文件应该先 save，在 callback里看到上传成功后再去 addObject:imageFile
