ios - 设置背景图像时 UILabel 不显示文本

Question

我尝试在 UITableViewCell 中为标签设置背景图片，但是在运行时，标签中只显示背景图片，不显示文本。

这是我的代码

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

    static NSString *CellIdentifier = @"TableCell";

    // Dequeue or create a cell of the appropriate type.
    TableCell *cell = (TableCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];


    if (cell == nil) {
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"TableCell" owner:self options:nil];
    cell = [nib objectAtIndex:0];
    UIImageView *preparationLabelBg = [[UIImageView alloc]
                                    initWithImage:[UIImage imageNamed:@"cellbg.jpeg"]];
    [cell.preparationLabel addSubview:preparationLabelBg];
    cell.preparationLabel.backgroundColor=[UIColor clearColor];
    [cell.preparationLabel sendSubviewToBack:preparationLabelBg];
    [cell.preparationLabel setOpaque:NO];

}

[cell.preparationLabel setFont:[UIFont fontWithName:@"Marker Felt" size:14]];

// Configure the cell.
if (btnselected==1)
{
    cell.preparationLabel.text = [recipe.ingredients objectAtIndex:indexPath.row];
}
else
{
 cell.preparationLabel.text = [recipe.preparation objectAtIndex:indexPath.row];
}
return cell;

为什么这里不显示文本？有人可以帮忙吗？

试试这段代码，

theLabel.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"cellbg.jpeg"]];
