AFN使用報錯：
Error Domain=NSCocoaErrorDomain Code=3840 "JSON text did not start with array or object and option to allow fragments not set." UserInfo={NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}網上查了查資料，AFN返回的數據responseObject預設以JSON的方式處理，如果返回的是個HTML或者其他的就會報錯。。解決辦法，告訴AFN返回的數據不用JSON處理。代碼就一句，如下：
manager.responseSerializer = [AFHTTPResponseSerializer serializer]
