问题找到了, iOS原生代码,Downloader.m文件中,有判断,如果[_statusCode isEqualToNumber:[NSNumber numberWithInt:200]]才会进入进度更新的回调. 其它一概不接受.我们服务端返回的是_statusCode 等于 201.

I think it is necessary to fix this problem.

@xclidongbo it looks like when I provide begin callback together with progress (even when begin is noop function), then progress is working correctly again.

Can you check?

@sebinq you saved my day, thanks!

mine too! thanks @sebinq but funny, I remember this working without begin

@LuisRodriguezLD yep, it was working before just fine. I don't know what what has changed :D But it is good that there is this hack which make it works again.
