TableView reloadData不会在iPad中更新UI，但可以在iPhone中使用

我有一个奇怪的错误。我使用UITableView它具有当获得所选择的行重新加载。这在iPhone模拟器中可以正常工作。在iPad上运行时，didSelectRowAtIndexPath被调用，但UI并未更新。我尝试reloadData在主线程上调用该方法。还是一样。

我已经在stackoverflow中尝试了各种解决方案。似乎没有什么能解决我的问题。

更新

当我选择一个单元格时，将添加新的单元格。因此，我需要重新加载表格视图以显示动态更改。在下面发布我的代码

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath: (NSIndexPath *)indexPath
{
NSUInteger count=indexPath.row+1;

NSMutableArray *insertIndexPaths = [NSMutableArray array];

[insertIndexPaths addObject:[NSIndexPath indexPathForRow:count inSection:indexPath.section]];

switch (indexPath.row) {
        case 0:
    {
    if ([ItemsInSection[indexPath.section] count]==1){
                [ItemsInSection[indexPath.section] addObject:obj2];

                [TabView beginUpdates];
                [TabView insertRowsAtIndexPaths:insertIndexPaths withRowAnimation:UITableViewRowAnimationLeft];

                [TabView endUpdates];        
            }
            else {

                [ItemsInSection[indexPath.section] removeAllObjects];
                [ItemsInSection[indexPath.section] addObject:obj1];

                [self.TabView reloadData];

            }
        }
            break;

        case 1:

    {if ([ItemsInSection[indexPath.section] count]==2){
                [ItemsInSection[indexPath.section] addObject:obj3];

                [self.TabView beginUpdates];
                [TabView insertRowsAtIndexPaths:insertIndexPaths withRowAnimation:UITableViewRowAnimationLeft];
                [self.TabView endUpdates];

            }
            else
            {
                [ItemsInSection[indexPath.section] removeAllObjects];
                [ItemsInSection[indexPath.section] addObject:obj1];
                [ItemsInSection[indexPath.section] addObject:obj2];

                [self.TabView reloadData];
              }
        }
            break;

        case 2: {

            if ([ItemsInSection[indexPath.section] count]==3) {
                 [ItemsInSection[indexPath.section] addObject:obj4];
                [self.TabView beginUpdates];
                 [TabView insertRowsAtIndexPaths:insertIndexPaths withRowAnimation:UITableViewRowAnimationLeft];
                [self.TabView endUpdates];

            }
            else
            {
                [ItemsInSection[indexPath.section] removeObject:obj4];
                [self.TabView beginUpdates];
                 [TabView deleteRowsAtIndexPaths:insertIndexPaths withRowAnimation:UITableViewRowAnimationLeft];

                [self.TabView endUpdates];

            }
          }
            break;

                  default:
            break;
    }

}
