AFNetworking Error Domain = com.alamofire.error.serialization.response Code = -1011＆＃34;请求失败：未找到（404）＆＃34;

Question

在AFNetworking中出错。错误Domain = com.alamofire.error.serialization.response Code = -1011 成功块永远不会被召唤。 这个错误意味着什么...我没有使用Alamofire然后为什么它会给出错误，如

  

Domain = com.alamofire.error.serialization.response Code = -1011
