ios - NSMutableArray in Custom cell implementation issue -

so had code on specialoffercell.h

#import <uikit/uikit.h> #import "afimagepager.h" @interface specialoffercell : uitableviewcell<afimagepagerdatasource,afimagepagerdelegate> @property (nonatomic, retain) nsmutablearray *arrayimages; @property (nonatomic) nsinteger offer_id; -(void)loadimages; @property (weak, nonatomic) iboutlet afimagepager *imageicons; @property (weak, nonatomic) iboutlet uilabel *titlelabel; @property (weak, nonatomic) iboutlet uilabel *desclabel;  @end 

and implementation file

#import "specialoffercell.h"  @implementation specialoffercell @synthesize arrayimages; - (id)initwithstyle:(uitableviewcellstyle)style reuseidentifier:(nsstring *)reuseidentifier { self = [super initwithstyle:style reuseidentifier:reuseidentifier]; if (self) {  } return self; }   - (void)awakefromnib  { // initialization code self.imageicons.delegate=self; self.imageicons.datasource=self;   }    -(nsarray*)getarrayimages{  return  [nsarray arraywitharray:arrayimages];  } #pragma mark - afimagepager datasource - (nsarray *) arraywithimageurlstrings {  return [self getarrayimages]; }  - (uiviewcontentmode) contentmodeforimage:(nsuinteger)image {   return uiviewcontentmodescaleaspectfill;  } - (uiimage *) placeholderimageforimagepager{   return [uiimage imagenamed:@"stub_dashboard"]; }  -(void)loadimages{ nslog(@"offer id :%d",self.offer_id); nslog(@"arrayimages:%d",arrayimages.count); @try {     if (arrayimages.count==0) {         nserror* error;         nsmutableurlrequest *request = [[nsmutableurlrequest alloc] init] ;         [request seturl:[nsurl urlwithstring:[appconfig url_get_offer_gallery]]];          nsstring *post = [nsstring stringwithformat:@"{\"hotel_id\":\"%@\",\"key\":\"%@\",\"offer_id\":%ld}",@"ayodya",[appconfig api_key],(long)_offer_id];         nslog(@"%@",post);         nsdata *postdata = [post datausingencoding:nsutf8stringencoding allowlossyconversion:yes];         nsstring *postlength = [nsstring stringwithformat:@"%lu", (unsigned long)[postdata length]];         [request sethttpmethod:@"post"];         [request setvalue:postlength forhttpheaderfield:@"content-length"];         [request setvalue:@"application/json" forhttpheaderfield:@"content-type"];  // multipart/form-data         [request sethttpbody:postdata];           nsdata *returndata = [nsurlconnection sendsynchronousrequest:request returningresponse:nil error:nil];         //nsstring *returnstring = [[nsstring alloc] initwithdata:returndata encoding:nsutf8stringencoding];         //nslog(@"%@",returnstring);         nsdictionary* json = [nsjsonserialization jsonobjectwithdata:returndata options:kniloptions error:&error];         arrayimages=[[nsmutablearray alloc]init];         nsmutablearray *arrayimagestemp=[[nsmutablearray alloc]init];         arrayimagestemp=[json objectforkey:@"galeries"];         (int i=0; i<arrayimagestemp.count; i++) {             nsdictionary * object=[[nsdictionary alloc]init];             object=[arrayimagestemp objectatindex:i];             [arrayimages addobject:[object objectforkey:@"image"]];         }         [self.imageicons reloaddata];      }  } @catch (nsexception *exception) {  } }  @end 

so when called custom cell in uitableviewcontroller array image using array has been used before, when initizialize new cell, array not refreshed. why that? because dequeuereusablecellwithidentifier?

data source:

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath  {  nsdictionary * object=[[nsdictionary alloc]init];  object=[array objectatindex:indexpath.row];  static nsstring *cellidentifier = @"specialoffercell";  specialoffercell *cell = (specialoffercell *)[tableview                                        dequeuereusablecellwithidentifier:cellidentifier];   cell.titlelabel.text=[object objectforkey:@"offer_title"];  [cell setoffer_id:[[object objectforkey:@"offer_id"]integervalue]];   [cell performselectorinbackground:@selector(loadimages) withobject:nil];   return cell;  } 

so going achieve here is, when cell have loaded images, wont load again.

in specialoffercell need implement prepareforreuse here can reset data such image array
