iphone - iOS - DetailViewController not displaying multiple entries/values from JSON -

i'm creating simple ipad app detailviewcontroller. works great, when try use multiple level json, doesn't work anymore app crashes.

i retrieve , loop through data:

-(void) retrievedata{      nsurl * url = [nsurl urlwithstring:getdataurl];     nsdata * data = [nsdata datawithcontentsofurl:url];      jsonarray = [nsjsonserialization jsonobjectwithdata:data options:kniloptions error:nil];      fruitarray = [[nsmutablearray alloc] init];      //loop through jsonarray     for(int =0;i < jsonarray.count;i++){          nsstring * cname = [[jsonarray objectatindex:i] valueforkey:@"cityname"];         nsstring * cfruit = [[jsonarray objectatindex:i] valueforkey:@"fruit"];          //add object fruitarray array         [fruitarray addobject:[[fruits alloc]initwithcitydocumentname:cname andfruit:cfruit]];      }     //reload table view     [self.tableview reloaddata]; } 

using json:

[{     "id": "1",     "cityname": "london",     "fruit":"apple" }, {     "id": "2",     "cityname": "berlin",     "fruit":"pear" }] 

and set labels(i hook them storyboard/nib):

- (void)setlabels{     citynamelabel.text = currentcity.documentname;     fruitlabel.text = currentcity.documentfruit; } 

all above work fine.

but create multiple values in json fruits, not work! new json:

[{     "id": "1",     "cityname": "london",     "fruit":         ["apple", "pear", "orange", "lemon"] }, {     "id": "2",     "cityname": "berlin",     "fruit":         ["mango", "melon", "tomatoe", "avocado"] }] 

it looks me need somehow programatically create labels , loop on them? basically, need see multiple values in detail view controller each id how can it?

i need here :( thank you.

edit: able create array rather strings when i'm creating buttons them won't let me add title based on what's in array:

nsmutablearray * cfruit = [[jsonarray objectatindex:i] valueforkey:@"fruit"]; 

and then:

- (void)setlabels{           for(int i=0;i<=currentcity.documentfruit.count;i++){          uibutton *button = [uibutton buttonwithtype:uibuttontyperoundedrect];          [button addtarget:self                    action:@selector(setlabels)          forcontrolevents:uicontroleventtouchupinside];         //below error - looks doesn't setting titles array         [button settitle:[currentcity.documentfruit objectatindex:i] forstate:uicontrolstatenormal];          button.frame = cgrectmake(20.0, buttonheightplusoffsetbetweenbuttons * , 280.0, 40.0);          //set tag future identification         [button settag:i];          [self.view addsubview:button];      }     } 

here providing complete code, so

#import "viewcontroller.h" #import "fruitsbo.h"  @interface viewcontroller ()  @property (strong, nonatomic) iboutlet uitableview *tblfruit; @property (nonatomic, strong) nsmutablearray *arrfruitdata; @end  @implementation viewcontroller @synthesize arrfruitdata;  - (void)viewdidload {     [super viewdidload];     // additional setup after loading view, typically nib.      arrfruitdata = [[nsmutablearray alloc] init];     [self loadlocaljson]; }   -(void)loadlocaljson {     nsstring *pathstringtolocalfile = [[nsbundle mainbundle] pathforresource:@"fruit" oftype:@"json"];      nserror *deserializingerror;     nsurl *localfileurl = [nsurl fileurlwithpath:pathstringtolocalfile];     nsdata *contentoflocalfile = [nsdata datawithcontentsofurl:localfileurl];     nsarray *objects = [nsjsonserialization jsonobjectwithdata:contentoflocalfile                                                 options:nsjsonreadingallowfragments                                                   error:&deserializingerror];      [self parsefruit:objects]; }   -(void)parsefruit:(nsarray *)arrfruits {      (nsdictionary *dicttemp in arrfruits) {         fruitsbo *fruit = [[fruitsbo alloc] init];          fruit.fruitid = [dicttemp objectforkey:@"id"];         fruit.cityname = [dicttemp objectforkey:@"cityname"];         fruit.arrfruit = [dicttemp objectforkey:@"fruit"];          [arrfruitdata addobject:fruit];         fruit = nil;     }      [self.tblfruit reloaddata]; }  #pragma mark - tableview delegate - - (nsinteger)numberofsectionsintableview:(uitableview *)tableview {     return [self.arrfruitdata count]; }  - (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section {     fruitsbo *obj = [self.arrfruitdata objectatindex:section];     return [obj.arrfruit count]; }  -(cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath {     return 50; }  - (cgfloat)tableview:(uitableview *)tableview heightforheaderinsection:(nsinteger)section {     return 30; }  - (nsstring *)tableview:(uitableview *)tableview titleforheaderinsection:(nsinteger)section {     fruitsbo *obj = [self.arrfruitdata objectatindex:section];     return obj.cityname; }  - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {     static nsstring *simpletableidentifier = @"fruitidentifier";      uitableviewcell *cell = [tableview dequeuereusablecellwithidentifier:simpletableidentifier];      if (cell == nil) {         cell = [[uitableviewcell alloc] initwithstyle:uitableviewcellstyledefault reuseidentifier:simpletableidentifier];     }      fruitsbo *objtemp = [self.arrfruitdata objectatindex:indexpath.section];      cell.textlabel.text = [objtemp.arrfruit objectatindex:indexpath.row];      return cell; }  - (void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath *)indexpath {     [tableview deselectrowatindexpath:indexpath animated:yes]; }   - (void)didreceivememorywarning {     [super didreceivememorywarning];     // dispose of resources can recreated. }  @end 

here json

 [{   "id": "1",   "cityname": "london",   "fruit":   ["apple", "pear", "orange", "lemon"]   }, {   "id": "2",   "cityname": "berlin",   "fruit":   ["mango", "melon", "tomatoe", "avocado"]   },{   "id": "2",   "cityname": "austin",   "fruit":   ["mango"]   }] 

here output
