数据未在tableView中加载，也未更新配置文件

Question

我是目标C的新手。执行此程序ON点击按钮“点击此处立即销售你的金牌”它将在午餐仪表盘中点击。在仪表板中选择交易历史。我在TransactionHistoryViewController.m文件中有fetchNewHothistory函数，负责从中获取数据url并将其显示在viewcontroller文件中

-(void)fetchNewHothistory
{
    NSTimer *t = [NSTimer scheduledTimerWithTimeInterval:1.0
                                                  target: self
                                                selector:@selector(mytimerChecking:)
                                                userInfo: nil repeats:NO];

    NSMutableDictionary *paramDict=[NSMutableDictionary dictionary];
    [paramDict setObject:@"ios" forKey:@"request"];
    [paramDict setObject:[NSString stringWithFormat:@"%@",currentUser.user_id] forKey:@"user_id"];
    [paramDict setObject:[NSString stringWithFormat:@"%@",self.currentLimitNew] forKey:@"limit_start"];

    [GeneralWebservices webserviceMainSplashCall:paramDict webserviceName:Webservice_TransactionHistory OnCompletion:^(id returnDict, NSError *error) {

        if ([returnDict[@"success"] intValue] ==1)
        {
//                        UIAlertView* alert = [[UIAlertView alloc] init];
//                        [alert setTitle:@"RECORD FOUND"];
//                       // [alert setMessage:returnDict[@"message"]];
//                        [alert addButtonWithTitle:@"OK"];
//                        [alert show];

            [history addObjectsFromArray:returnDict[@"data"]];
            self.currentLimitNew=[NSString stringWithFormat:@"%@",returnDict[@"limit_start"]] ;
            [historyTableView reloadData];
        }
        else
        {
            UIAlertView* alert = [[UIAlertView alloc] init];
            [alert setTitle:@"RECORD FOUND"];
            //[alert setMessage:returnDict[@"message"]];
            [alert addButtonWithTitle:@"OK"];
            [alert show];
        }
        [MBProgressHUD hideAllHUDsForView:self.view animated:YES];
        [historyTableView.pullToRefreshView stopAnimating];
        [historyTableView.infiniteScrollingView stopAnimating];

    }];

}

问题-1找到记录但在选择事务历史记录时ViewController上没有显示任何内容。如何在viewcontroller上显示记录？

问题-2在选择Profile时，执行ProfileViewController.m。更新用户配置文件。它不会更新。它仍然保持缓冲。如何执行配置文件更新。你可以从这个链接下载该项目.https://drive.google.com/file/d/1daW4veZAI21b8TqKFHauSFTboHKJceaG/view?usp=sharing

试试这个：

dispatch_async(dispatch_get_main_queue(), ^{

      [historyTableView reloadData];

   });
