问题：我怎样才能删除 UIButton 的所有子视图？如果我删除所有子视图，它也会删除单元格标题。

    var height:CGFloat = 0
    cell.backgroundColor = UIColor.whiteColor()
    cell.accessoryType = UITableViewCellAccessoryType.DisclosureIndicator

    if(indexPath == selectedIndexPath){
        cell.backgroundColor = UIColor.grayColor()
        for i in 0...deptProfile.count-1 {
            let deptmentProfile = UIButton(frame: CGRectMake(0,44+height,400,41))
            deptmentProfile.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside)
            height = height+41
            deptmentProfile.setTitle(deptProfile[i] as! String, forState: UIControlState.Normal) …
