tableview - uitableview を閉じて別の uitableview をリロードする

Question

問題があります。

私は CityViewController.m を持っています

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
  UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
  TheatreController *tmpTheatreController = [storyboard instantiateViewControllerWithIdentifier:@"TheatreController"];
  NSString *cityView = [[self.arrayCity objectAtIndex:indexPath.row] valueForKey:@"idCity"];
  tmpTheatreController.cityView = cityView;

  //[self.navigationController pushViewController:tmpTheatreController animated:YES];
  [tmpTheatreController.tableView reloadData];
  [self.delegate citiesViewControllerCancel:self];    
}

都市を選択すると、TheatreController.m の「idCity」が正しく渡されます

...
-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
   if([segue.identifier isEqualToString:@"SelectCity"])
   {
      UINavigationController *nc = segue.destinationViewController;
      CityViewController *mvc = [[nc viewControllers] objectAtIndex:0];
      mvc.delegate = self;
   }
}
...
- (void)viewDidLoad
{
  [super viewDidLoad];


  NSString *webUrl = @"http://localhost:3000/theatres?city=";
  webUrl = [webUrl stringByAppendingFormat:@"%@", cityView];
  dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
    NSData* data = [NSData dataWithContentsOfURL:[NSURL URLWithString:webUrl]];
    [self performSelectorOnMainThread:@selector(fetchedData:)
                           withObject:data waitUntilDone:YES]; });
    }
- (void)fetchedData:(NSData *)responseData {
   NSArray* json = [NSJSONSerialization
                 JSONObjectWithData:responseData
                 options:kNilOptions error:nil];
   NSMutableArray *theatreTMP = [[NSMutableArray alloc] initWithCapacity:[json count]];

   int i = 0;
   for (id object in [json valueForKeyPath:@"response.name"]) {
     Theatres *t = [[Theatres alloc] init];
     NSLog(@"JSON: %@", [[json valueForKeyPath:@"response.name"] objectAtIndex:i]);
     t.theatre = [[json valueForKeyPath:@"response.name"] objectAtIndex:i];
     t.idTheatre = [[json valueForKeyPath:@"response.id"] objectAtIndex:i];

     [theatreTMP addObject:t];
     i++;
  }
 self.arrayTheatre = [theatreTMP copy];
 [self.tableView reloadData];
}

サーバーの応答は正しく、すべてのパラメーターは正しいですが、tableView メインの reloadData に問題があります![ここに画像の説明を入力][1]。更新テーブルが表示されません。

助けて ありがとう
