我在创建 时遇到问题UITableView，因为我在其中一个单元格中看不到我分配给它的标签和步进器。

这是代码，我希望有人能解决问题。当它到达案例 4 时，它不会在单元格中显示 lblVarsta，只显示步进器。我调试了它，值在那里，但是看不到带有该值的标签。谢谢！

   - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:    (NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
UITextField *inputField;

lblRasa = [[UILabel alloc]initWithFrame:CGRectMake(120, 12, 185, 30)];
lblCuloare = [[UILabel alloc]initWithFrame:CGRectMake(120, 12, 185, 30)];
lblJudet = [[UILabel alloc]initWithFrame:CGRectMake(120, 12, 185, 30)];
lbldate = [[UILabel alloc] initWithFrame:CGRectMake(120, 12, 185, 30)];

inputField = [[UITextField alloc]initWithFrame:CGRectMake(120, 12, 185, 30)];
inputField.adjustsFontSizeToFitWidth = YES;
inputField.borderStyle = UITextBorderStyleRoundedRect;
inputField.tag = indexPath.row;
inputField.delegate = self;


segmentedControl1 = [[UISegmentedControl alloc] initWithFrame:CGRectMake(220, 10, 100, 10)];

你有

    [cell addSubview:lblVarsta];
    [cell.contentView addSubview:stepper];

和 lblVarsta = [[UILabel alloc] initWithFrame:CGRectMake(120, 12, 185, 30)]; stepper = [[UIStepper alloc] initWithFrame:CGRectMake(220, 10, 100, 10)];

你为什么不试试

     [cell.contentView addSubview:stepper];
     [cell.contentView addSubview:lblgarsta];

框架如下

    lblVarsta = [[UILabel alloc] initWithFrame:CGRectMake(120, 12, 100, 30)];
    stepper = [[UIStepper alloc] initWithFrame:CGRectMake(220, 10, 100, 10)];

您必须将两个子视图都添加到内容视图中，并且它们的框架必须使它们都可以出现。
