ios - Adding cell from one tableView to another -

in relation other question, tried few things add cell 1 tableview new one. first of have little picture shows how process should work. there carsviewcontroller containing array of cars. when tap on 1 cell new view (cardetailviewcontroller) shows details of each car , has got favoritebutton opens. tapping on button cell of car tableview (carsviewcontroller) should added new tableview (favviewcontroller) can see in picture.

i've tried didn't work. car class:

#import "car.h" @implementation car @synthesize name; @synthesize speed;  @end 

carsviewcontroller:

@implementation carsviewcontroller {     nsarray *cars; }  @synthesize tableview = _tableview;  - (void)viewdidload {     car *car1 = [car new];     car1.name = @"a1";     car1.speed = @"200 km/h";    car *car2 = [car new];     car2.name = @"a2";     car2.speed = @"220 km/h";  cars = [nsarray arraywithobjects:car1, car2, nil]; } 

the cardetailviewcontroller button:

    @implementation cardetailviewcontroller{         nsmutablearray *favoritesarray;     } ...     - (ibaction)setfav:(id)sender {          [favoritesarray addobject:car];          [[nsuserdefaults standarduserdefaults] setobject:favoritesarray forkey:@"favoritecars"];          } 

and favviewcontroller:

@implementation favviewcontroller{      nsmutablearray *array; } - (void)viewdidload {     [super viewdidload];     array = [nsmutablearray arraywitharray:[[nsuserdefaults standarduserdefaults] objectforkey:@"favoritecars"]];   } - (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section {         return [array count];      }  - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {     static nsstring *simpletableidentifier = @"cell2";      uitableviewcell *cell = [tableview dequeuereusablecellwithidentifier:simpletableidentifier];      if (cell == nil) {         cell = [[uitableviewcell alloc] initwithstyle:uitableviewcellstyledefault reuseidentifier:simpletableidentifier];     }      car *cars2 = [array objectatindex:indexpath.row];     uilabel *carnamelabel = (uilabel *)[cell viewwithtag:100];     carnamelabel = cars2.name;      return cell; } 

update

i`ve tried remove 1 cell tableview after reloading view cells away.

-(void)remove{     [favoritesarray removeobject:car];     [[nsuserdefaults standarduserdefaults] setobject:[nskeyedarchiver archiveddatawithrootobject:favoritesarray] forkey:@"favoritecars"]; } //in cardetailview 

and...

- (void)tableview:(uitableview *)table commiteditingstyle:(uitableviewcelleditingstyle)editingstyle forrowatindexpath:(nsindexpath *)indexpath {      if (editingstyle == uitableviewcelleditingstyledelete)     {          cardetailviewcontroller *instance = [[cardetailviewcontroller alloc] init];         [instance remove];           [array removeobjectatindex:indexpath.row];         [self.tableview deleterowsatindexpaths:[nsarray arraywithobject:indexpath] withrowanimation:uitableviewrowanimationfade];      } } 

add car.m

- (void)encodewithcoder:(nscoder *)coder; {     [coder encodeobject:name forkey:@"name"];     [coder encodeobject:speed forkey:@"speed"]; }  - (id)initwithcoder:(nscoder *)coder; {     self = [[car alloc] init];     if (self != nil)     {         name = [coder decodeobjectforkey:@"name"];         speed = [coder decodeobjectforkey:@"speed"];     }        return self; } 

in setfav method store array

nsdata *dataforarray = [[nsuserdefaults standarduserdefaults] objectforkey:@"favoritecars"]; if (dataforarray != nil) {     favoritesarray = [nsmutablearray arraywitharray:[nskeyedunarchiver unarchiveobjectwithdata:dataforarray]];  }  [favoritesarray addobject:car]; [[nsuserdefaults standarduserdefaults] setobject:[nskeyedarchiver archiveddatawithrootobject:favoritesarray] forkey:@"favoritescars"]; 

and retrieve array in favorites view controller

nsdata *dataforarray = [[nsuserdefaults standarduserdefaults] objectforkey:@"favoritecars"]; if (dataforarray != nil) {     array = [nsmutablearray arraywitharray:[nskeyedunarchiver unarchiveobjectwithdata:dataforarray]];  } 

this makes custom objects conform nscoding can use nsuserdefaults.
