here code:

- (uicollectionviewcell *)collectionview:(uicollectionview *)collectionview cellforitematindexpath:(nsindexpath *)indexpath             {                 static nsstring *cellid = @"cellid";                 racollectionviewcell *cell = [self.collectionview dequeuereusablecellwithreuseidentifier:cellid forindexpath:indexpath];                 [cell.imageview removefromsuperview];                 cell.imageview.frame = cell.bounds;                 cell.imageview.image = [uiimage imagenamed:[_photosarray objectatindex:indexpath.item]];                 cell.backgroundcolor = [uicolor lightgraycolor];                 [cell.contentview addsubview:cell.imageview];              uibutton *addbtn =[[uibutton alloc]init];                  addbtn.tag=indexpath.row;              deletebtn.frame = cgrectmake(100, 100, 19, 19);                            uiimage *img=[uiimage imagenamed:@"ic_add_photo.png"];                            [addbtn setimage:img forstate:uicontrolstatenormal];                            [addbtn addtarget:self action:@selector(addbtnaction) forcontrolevents:uicontroleventtouchupinside];                [cell.contentview addsubview:addbtn];             return cell;             }     -(void)addbtnaction      {          uialertcontroller *actionsheetcontroller = [[uialertcontroller alloc]init];              uialertaction *library = [uialertaction actionwithtitle:@"choose library" style:uialertactionstyledefault handler:^(uialertaction         * action)                                       {                                                 // library button tapped                                                    [self performselector:@selector(librarybtnaction) withobject:nil];                                            }];                  [actionsheetcontroller addaction:library];             actionsheetcontroller.view.tintcolor = [uicolor darkgraycolor];                   [self presentviewcontroller:actionsheetcontroller animated:yes completion:nil];             }              -(void)librarybtnaction             {                  uiimagepickercontroller *picker  = [[uiimagepickercontroller alloc]init];                  picker.delegate = self;                  picker.allowsediting = yes;                  picker.sourcetype = uiimagepickercontrollersourcetypephotolibrary;                  [self presentviewcontroller:picker animated:yes completion:nil];              } - (void)imagepickercontroller:(uiimagepickercontroller *)picker didfinishpickingmediawithinfo:(nsdictionary *)info  {                   chosenimage = info[uiimagepickercontrollereditedimage];                  cell.imageview.image = chosenimage;                  [_collectionview reloaddata];                   [picker dismissviewcontrolleranimated:yes completion:null];              } 

1. first problem in code , using "cell" object in didfinishpickingmediawithinfo , hell have defined that?

2. how specify in image view of collection cell, show image picked library?

just use tag tracking things , in end of picking image load cell specific tag using indexpath.item , reload specific cell.
