标签上没有显示的tableView细胞

我创建其中包含20个rows.I一个TableView有一个标签添加到偶数细胞，我必须在奇cells.When添加两个标签，我添加所需的标签和滚动我餐桌上的标签让我失望，因为我下去帮助我。标签上没有显示的tableView细胞

- (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)]; 
     [email protected]"o1"; 
     [cell addSubview:cellLabel]; 
     [cellLabel release]; 
    } 
    else 
    { 
     UILabel *cellLabel1=[[UILabel alloc]initWithFrame:CGRectMake(100, 40, 40, 40)]; 
     [email protected]"e1"; 
     [cell addSubview:cellLabel1]; 
     [cellLabel1 release]; 
     UILabel *cellLabel2=[[UILabel alloc]initWithFrame:CGRectMake(150, 40, 40, 40)]; 
     [email protected]"e2"; 
     [cell addSubview:cellLabel2]; 
     [cellLabel2 release]; 
    } 

}

的可能重复的[在的UITableViewCell文本丢失时向下滚动（http://stackoverflow.com/questions/1432143/text-in-uitableviewcell -missing-时，向下滚屏） – rishi

您需要tag'属性添加到''每一个的UILabel – iNoob

http://www.theappcodeblog.com/2011/02/24/table-view-tutorial-part-4-customizing -a-table-cell/ –

这两种细胞是不同的，所以我会为每个不同的小区标识符。例如：

- (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)]; 
      [email protected]"o1"; 
      [cell addSubview:cellLabel]; 
      [cellLabel release]; 
     } 
     else 
     { 
      UILabel *cellLabel1=[[UILabel alloc]initWithFrame:CGRectMake(100, 40, 40, 40)]; 
      [email protected]"e1"; 
      [cell addSubview:cellLabel1]; 
      [cellLabel1 release]; 
      UILabel *cellLabel2=[[UILabel alloc]initWithFrame:CGRectMake(150, 40, 40, 40)]; 
      [email protected]"e2"; 
      [cell addSubview:cellLabel2]; 
      [cellLabel2 release]; 
     } 
    } 

    return cell; 
}

我已经试过，但我再次向下滚动标签成为消失.... –

做这样的：

(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)]; 
     [email protected]"o1"; 
cellLabel.tag = 2; 
     [cell addSubview:cellLabel]; 
     [cellLabel release]; 

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

UILabel *label1 = (UILabel *) [cell viewWithTag:2]; 
UILabel *label2 = (UILabel *) [cell viewWithTag:3]; 
UILabel *label3 = (UILabel *) [cell viewWithTag:4]; 

if (indexPath.row%2==0) 
{ 
label1.hidden = FALSE; 
label2.hidden = TRUE; 
label3.hidden = TRUE: 
} 
else 
{ 
label1.hidden = TRUE; 
label2.hidden = FALSE; 
label3.hidden = FALSE; 
} 

    }

@RAjKumar ---- not worki NG。 –

移除所有标签释放语句，然后再试一次，我相信它会工作 – Rajkumar

由NNC一看便知上面... –

选中此项。这与您的代码相同，我只需更改每个标签的Y位置并使用滚动功能也可以正常工作。

- (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)]; 
     [email protected]"o1"; 
     [cell addSubview:cellLabel]; 

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

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

    } 

} 
return cell;

}

如果你是使用默认行高，那么你的标签就会移出相对单元格。正如你已经给出Y = 40，默认行高为44. – Nikunj

thanx !!!，它的工作原理！ –

{ 
    static NSString *MyIdentifier = @"MyIdentifier"; 
    static NSString *MyIdentifier1 = @"MyIdentifier1";

    if(indexPath.row % 2 != 0) 
    { 
     cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
