objective c - Issue with parsing JSON data -

i trying convert string json object , unsure why not working. when nslog output told urldata not valid json serialization when looking @ string looks me valid json. have tried encoding utf8 still won't serialize. missing here? - note unnecessary code omitted post.

get request

urldata = [nsurlconnection sendsynchronousrequest:urlrequest                                 returningresponse:&response                                             error:&error];  nsdictionary *tempdict = [nsdictionary alloc]; 

parsing

if ([nsjsonserialization isvalidjsonobject:urldata] ) {     nslog(@"is valid");     tempdict = [nsjsonserialization jsonobjectwithdata:urldata kniloptions error:&error]; }  nslog(@"is not valid"); 

definition: isvalidjsonobject: returns boolean value indicates whether given object can converted json data.

as mentioning in question, isvalidjsonobject

returns boolean value indicates whether given object can converted to json data

in case, don't want create json data, instead create dictionary out of json data. :

tempdict = [nsjsonserialization jsonobjectwithdata:urldata                                            options:nsjsonreadingmutablecontainers                                              error:&error];  if (!tempdict) {   nslog(@"error parsing json: %@", error); }
