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]; }

i'm trying subclass qstyleditemdelegate remove focus rectangle in qcombobox . even though i'm calling base implementation of paint function , nothing else, result different. looks if parts of style-sheet influence bounding box of item taken consideration. class pstyleditemdelegate(qstyleditemdelegate): def __init__(self, *args, **kwds): super(pstyleditemdelegate, self).__init__(*args, **kwds) def paint(self, *args, **kwargs): qstyleditemdelegate.paint(*args, **kwargs) what have paint unmodified qstyleditemdelegate ? as suggested tried replacing pyside pyqt4 , works, appears bug. update pyside 1.1.2 1.2.1 result same. unfortunately switch breaks other parts of code, if there no other suggestions i'm going accept answer. edit bug tracked here

i using node.js script gather data stackoverflow. know responses gzipped, put code in should take care of that. script follows: var request = require('request'); var zlib = require('zlib'); function getstackoverflowresponse(url, callback){ request(url, {encoding: null}, function(err, response, body){ if(response.headers['content-encoding'] == 'gzip'){ zlib.gunzip(body, function(err, dezipped) { callback(dezipped); }); } else { callback(body); } }); } var url = "https://api.stackexchange.com/docs/questions#pagesize=2&order=desc&min=2014-01-04&max=2014-02-02&sort=activity&tagged=apigee&filter=default&site=stackoverflow&run=true"; getstackoverflowresponse(url, function(questions) { console.log(questions); }); instead of getting json output, i'm getting following response: buffer 0d 0a 0d 0a 0d 0a 0d 0a 3c 21 44 4f 43 54 59 50 45 20 48...
