iphone - implement prototype cell when I click a button in another view Controller -

-

my program has 1 view controller , tableview controller. intend upgrade tableview cell current time everytime click button in viewcontroller.

viewcontroller.m

@interface viewcontroller ()   @property(nonatomic,strong) brain* brain;   @property(nonatomic,readonly)timetablecontroller* tablecontrol; @end  - (void)viewdidload {   [super viewdidload];   _brain=[[brain alloc] init];   _tablecontrol=[[timetablecontroller alloc] init]; } - (ibaction)actiontime:(id)sender {    [self.tablecontrol.entrytime addobject:[self.brain currenttime]]; }

timetablecontroller.h

@property (strong, nonatomic) iboutlet uitableview *timetable; @property(nonatomic,strong) nsmutablearray* entrytime;

timetablecontroller.m

- (void)viewdidload {   [super viewdidload];    _entrytime=[[nsmutablearray alloc] init];   _timetable=[[uitableview alloc] init];     #pragma mark - table view data source   - (nsinteger)numberofsectionsintableview:(uitableview *)tableview  {   if(!_entrytime) return 0;   else       return 1;   }    - (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section  {    return [_entrytime count];   }   - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath  { ...   self.cell.timelabel.text = [nsstring stringwithformat:@"%@",[self.entrytime objectatindex:[indexpath row]]];   } [self.tablecontrol.timetable reloaddata];  return cell; }

however, when press button, nothing happens. can me solve it?

where 

@property(nonatomic,strong) nsstring* timelabel;

?

then dont forget connect in xib file after placing label in custom cell located in xib file.
