objective c - Converting JSON Result as an Array -

i have json data :

array: {     data = (                 {             "com_id" = 1;             "com_name" = apple;         },                 {             "com_id" = 2;             "com_name" = "google";         },                {             "com_id" = 3;             "com_name" = "yahoo";         }     );     message = "data found";     response = success; } 

here's code fetch data :

    nsurl * url = [[nsurl alloc] initwithstring:@"https://jsonurlhere.com"];      // prepare request object     nsurlrequest *urlrequest = [nsurlrequest requestwithurl:url                                                 cachepolicy:nsurlrequestreturncachedataelseload                                             timeoutinterval:30];      // prepare variables json response     nsdata *urldata;     nsurlresponse *response;     nserror *error;      // make synchronous request     urldata = [nsurlconnection sendsynchronousrequest:urlrequest                                     returningresponse:&response                                                 error:&error];      // construct array around data response     nsarray* object = [nsjsonserialization                        jsonobjectwithdata:urldata                        options:0                        error:&error];      nslog(@"array: %@", object); 

now, want use json data pickerview. how change json data array can load replace existing array (self.namecompany)?

- (void)viewdidload {     [super viewdidload];     // additional setup after loading view, typically nib.     self.namecompany = @[@"apple", @"google", @"yahoo"]; } 

check code , response not array dictionary.

-(void)loaddata{  nsurl * url = [[nsurl alloc] initwithstring:@"https://jsonurlhere.com"];  // prepare request object nsurlrequest *urlrequest = [nsurlrequest requestwithurl:url                                             cachepolicy:nsurlrequestreturncachedataelseload                                         timeoutinterval:30];  // prepare variables json response nsdata *urldata; nsurlresponse *response; nserror *error;  // make synchronous request urldata = [nsurlconnection sendsynchronousrequest:urlrequest                                 returningresponse:&response                                             error:&error];  // construct array around data response nsdictionary* object = [nsjsonserialization                    jsonobjectwithdata:urldata                    options:0                    error:&error];  nslog(@"array: %@", [object objectforkey:@"data"]);   nsmutablearray *companyarray=[[nsmutablearray alloc] init];  (nsdictionary *tempdict in [object objectforkey:@"data"]) {      [companyarray addobject:[tempdict objectforkey:@"com_name"]]; }  self.namecompany=[nsarray arraywitharray:companyarray]; }
