我在數據庫中插入兩條記錄兩個數據都不同，但是當我得到一個數據並在tableView中顯示。我看到我的第一個數據被tableview中的第二個數據覆蓋，第二個數據在tableview中顯示兩次。無法在ios中的tableview sqlite3中顯示正確的數據

cell.textLabel.text = DBPersonDetail.dbfullName;

UIStoryboard *storybrd = self.storyboard;
ClsChangeNetworkViewController *svc = [storybrd instantiateViewControllerWithIdentifier:@"editcontactcontrol"];
[self presentViewController:svc animated:YES completion:nil ];
}
我插入兩個記錄由兩個不同的名字，但我看到第一名稱數據不是在表格視圖中可見並且第二名稱數據在表格視圖中可見兩次。也許問題發生在類ClsChangeNetworkViewController.m in viewDidLoad。
請解決我的問題。
感謝
