我正在创建包含一些行的表视图数量。我必须使用复选框选择多行并使用按钮移动到下一个表格视图。问题是，当我从一个表格视图移动到另一个表格视图时，使用 NEXT 按钮选择行，即复选框保持不变。意味着当我选择表视图的第二行时，所有表视图都选择了第二行。我想为不同的表格视图获得不同的选择。这是我的代码，请帮助

            {
                [checkedArr addObject:@"1"];
            }
            NSLog(@"Checked arr size %i",[checkedArr count]);

首先，您通过 xib 设置表视图的标识符。

在您的按钮操作中尝试此操作：

   if([tableView1 identifier] isEqualToString:@"XYZ"])
       {
         //Do for 1st table
       }
       if([tableView2 identifier] isEqualToString:@"ABC"])
       {
         //Do for 2nd table
       }

tableView1 和 tableView2 是表视图的出口。

试试这个方法...

- (NSInteger)tableView:(UITableView *)aTableView numberOfRowsInSection:(NSInteger)section
{
    int p=0;
    if (aTableView==tbl_1)
    {
        p= [arr_tb1 count];
    }
    else if(aTableView == tbl_2)
    {
      p= [arr_tb2 count];
    }

    return p;

}


-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier=@"Cell";

    UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];

    if (cell == nil) {

        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    if (tableView==tbl_1)
    {
  }
  else if (tableView==tbl_2
{ }
return cell;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (tableView==tbl_!)
    {
   }
  else if (tableView==tbl_2)
{ }

}

如果您有任何问题，请告诉我。
