IOS怎么上传一个字典

[q877698700]

NSDictionary *dic=[NSDictionary dictionaryWithObjectsAndKeys:[datas objectForKey:@"order_id"],@"order_id",_isgeval,@"geval_isanonymous",_store_desccredit,@"store_desccredit",_store_servicecredit,@"store_servicecredit",_store_deliverycredit,@"store_deliverycredit",userModel.key,@"key",s2,@"goods",nil];

goods参数在后台格式"{201:{geval_scores:0,geval_content:555}}";

你需要把字典转成json格式，看这里： http://stackoverflow.com/questions/6368867/generate-json-string-from-nsdictionary 里面有两个类别，一个是把字典转成json，另一个是把数组转成json。
