滚动表视图时，标签的边角半径会变形

func setLabelCorner(radius: CGFloat) {
    label.layer.cornerRadius = radius
    label.layer.masksToBounds = true
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "CustomCell", for: indexPath) as! CustomCell
    let radius: CGFloat = 10.0 // 设置期望的边角半径
    cell.setLabelCorner(radius: radius)
    // 其他单元格设置逻辑...
    return cell
}
