i tried coding you.follow code , customize want add array , set dictionary.

nsdictionary *jsonarray = [nsjsonserialization jsonobjectwithdata:responsedata options: nsjsonreadingmutablecontainers error: &err];  nsarray *array=[jsonarray objectforkey:@"response"];  (int i=0;i<[array count];i++) {     nsmutabledictionary *dict = [array objectatindex:i];     nsmutablearray *arraydictvalue = [dict valueforkey:[nsstring stringwithformat:@"%d",0]];     nsstring *strmenuname = [nsstring stringwithformat:@"%@",[arraydictvalue valueforkey:@"menuname"]];     nsstring *strmenuid = [nsstring stringwithformat:@"%@",[arraydictvalue valueforkey:@"menuid"]];     nslog(@"the strmenuname is-%@",strmenuname);     nslog(@"the strmenuid is-%@",strmenuid);     (int j=0; j<[arraydictvalue count]; i++)     {         nsmutabledictionary *dictinside = [arraydictvalue objectatindex:j];         nsarray *arrayinsidedict = [dictinside valueforkey:@"0"];         (int k =0; k<[arrayinsidedict count]; i++)         {              nsstring *strcatname = [nsstring stringwithformat:@"%@",[[arrayinsidedict objectatindex:k ]valueforkey:@"catname"]];             nsstring *strcatid = [nsstring stringwithformat:@"%@",[[arrayinsidedict objectatindex:k ]valueforkey:@"catid"]];             nslog(@"the strcatename is-%@",strcatname);             nslog(@"the strcatid is-%@",strcatid);             nsmutabledictionary *dictinarray = [[arrayinsidedict objectatindex:0] valueforkey:@"0"];             nsstring *strscatname = [nsstring stringwithformat:@"%@",[dictinarray valueforkey:@"scatname"]];             nsstring *strscatid = [nsstring stringwithformat:@"%@",[dictinarray valueforkey:@"scatid"]];             nslog(@"the strscatname - %@",strscatname);             nslog(@"the strscatid - %@",strscatid);          }       }   }
