使用AFNetworking出现报错：
error=Error Domain=com.alamofire.error.serialization.response Code=-1016 "Request failed: unacceptable content-type: text/html" UserInfo=0x7fdfd8729680 {com.alamofire.serialization.response.error.response= { URL: http://172.16.1.31:7001/itom/getwork } { status code: 200, headers {
"Cache-Control" = "no-cache";
"Content-Type" = "text/html;charset=UTF-8";
Date = "Mon, 24 Nov 2014 03:13:16 GMT";
"Transfer-Encoding" = Identity;
"X-Powered-By" = "Servlet/2.5 JSP/2.1";
å
解决方法：
全工程搜索AFURLResponseSerialization.m文件
修改223行：
self.acceptableContentTypes = [NSSetsetWithObjects:@"application/json", @"text/html",@"text/json",@"text/javascript", nil];
加上蓝色部分，其实就是添加一种服务器返回的数据格式。
亲测，好使。
