20行を含むを作成してTableViewいます。偶数のセルに単一のラベルを追加し、奇数のセルに2つのラベルを追加する必要があります。目的のラベルを追加してテーブルをスクロールすると、下に行くとラベルが消えます。 。

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

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    // UITableView *cell=[tableView ]
if (cell == nil)
{
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];


    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    if(indexPath.row%2==0)
    {
        UILabel *cellLabel=[[UILabel alloc]initWithFrame:CGRectMake(100, 40, 40, 40)]; 
        cellLabel.text=@"o1";
        [cell addSubview:cellLabel];
        [cellLabel release];
    }
    else
    {
        UILabel *cellLabel1=[[UILabel alloc]initWithFrame:CGRectMake(100, 40, 40, 40)]; 
        cellLabel1.text=@"e1";
        [cell addSubview:cellLabel1]; 
        [cellLabel1 release];
        UILabel *cellLabel2=[[UILabel alloc]initWithFrame:CGRectMake(150, 40, 40, 40)]; 
        cellLabel2.text=@"e2";
        [cell addSubview:cellLabel2]; 
        [cellLabel2 release];
    }

}

これをチェックして。これは、各ラベルのY位置を変更しただけのコードと同じであり、スクロールでも正常に機能します。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{static NSString * CellIdentifier = @ "Cell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
// UITableView *cell=[tableView ]
if (cell == nil)
{
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];


    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    if(indexPath.row%2==0)
    {
        UILabel *cellLabel=[[UILabel alloc]initWithFrame:CGRectMake(100, 10, 40, 40)]; 
        cellLabel.text=@"o1";
        [cell addSubview:cellLabel];

    }
    else
    {
        UILabel *cellLabel1=[[UILabel alloc]initWithFrame:CGRectMake(100, 10, 40, 40)]; 
        cellLabel1.text=@"e1";
        [cell addSubview:cellLabel1]; 

        UILabel *cellLabel2=[[UILabel alloc]initWithFrame:CGRectMake(150, 10, 40, 40)]; 
        cellLabel2.text=@"e2";
        [cell addSubview:cellLabel2]; 

    }

}
return cell;

}

このようにしてください：

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



    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    // UITableView *cell=[tableView ]
    if (cell == nil)
    {
       cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];

    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;

    UILabel *cellLabel=[[UILabel alloc]initWithFrame:CGRectMake(100, 40, 40, 40)]; 
        cellLabel.text=@"o1";
cellLabel.tag = 2;
        [cell addSubview:cellLabel];
        [cellLabel release];

        UILabel *cellLabel1=[[UILabel alloc]initWithFrame:CGRectMake(100, 40, 40, 40)]; 
        cellLabel1.text=@"e1";
cellLable1.tag = 3;
        [cell addSubview:cellLabel1]; 
        [cellLabel1 release];
        UILabel *cellLabel2=[[UILabel alloc]initWithFrame:CGRectMake(150, 40, 40, 40)]; 
        cellLabel2.text=@"e2";
cellLabel2.tag = 4;
        [cell addSubview:cellLabel2]; 
        [cellLabel2 release];
    }

UILabel *label1 = (UILabel *) [cell viewWithTag:2];
UILabel *label2 = (UILabel *) [cell viewWithTag:3];

2種類のセルは異なるので、それぞれに異なるセル識別子を作成します。何かのようなもの：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *EvenCellIdentifier = @"EvenCell";
    static NSString *OddCellIdentifier = @"OddCell";
    NSString* cellIdentifier = (indexPath.row % 2) == 0 ? EvenCellIdentifier : OddCellIdentifier;

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
    if (cell == nil)
    {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier] autorelease];

        cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
        if(indexPath.row%2==0) 
        {
            UILabel *cellLabel=[[UILabel alloc]initWithFrame:CGRectMake(100, 40, 40, 40)]; 
            cellLabel.text=@"o1";
            [cell addSubview:cellLabel];
            [cellLabel release];
        }
        else
        {
            UILabel *cellLabel1=[[UILabel alloc]initWithFrame:CGRectMake(100, 40, 40, 40)]; 
            cellLabel1.text=@"e1";
            [cell addSubview:cellLabel1]; 
            [cellLabel1 release];
            UILabel *cellLabel2=[[UILabel alloc]initWithFrame:CGRectMake(150, 40, 40, 40)]; 
            cellLabel2.text=@"e2";
            [cell addSubview:cellLabel2]; 
            [cellLabel2 release];
        }
