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

Question

My program has one view controller and a tableView controller. I intend to upgrade my tableview cell with the current time everyTime I click a 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 I press the button, nothing happens. Can someone help me to solve it?

Answer 1

Where is your

@property(nonatomic,strong) NSString* timeLabel;

?

Then dont forget to connect that in your xib file after placing a label in your custom cell that is located in the xib file.
