ios - How to parse the data of JSON response in Objective-C? -

i got json output in link

i extracted id in output. (i.e)

419023188150340,
419023228150336,
419023278150331,
419023318150327,
419044998148159,
419045028148156

using following code

[[dict objectforkey:@"data"]valueforkey:@"id"]; 

dict has total output displayed on link

i displayed in tableview.
if once tap cell in tableview. table should fetch value of "picture" , display in console(nslog).

i used following code response , store in dictionary(here dict)

- (void)connection:(nsurlconnection *)connection didreceiveresponse:(nsurlresponse *)response  {     responsedata=nil;     idarray=nil;     responsedata=[[nsmutabledata alloc]init];     idarray=[[nsmutablearray alloc]init];     dict=[[nsdictionary alloc]init];    } - (void)connection:(nsurlconnection *)connection didreceivedata:(nsdata *)data  {     [responsedata appenddata:data]; } - (void)connectiondidfinishloading:(nsurlconnection *)connection  {     dict=[nsjsonserialization jsonobjectwithdata:responsedata options:0 error:null];     [idarray addobjectsfromarray:[[dict objectforkey:@"data"]valueforkey:@"id"]];     [tablevw reloaddata]; } 

can 1 tell me how this.

you doing wrong. first nsarray of ids , have loop on extract each id. try -

nsarray *fbids = [dict objectforkey:@"data"]; for(nsdictionary *fbid in fbids) {     nslog("fb id: %@", [fbid valueforkey:@"id"]); } 

once extract correct facebook_id, can use http://graph.facebook.com/419023188150340/picture picture. hope helps...
