UITableView 的cell左滑删除

    func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
    
            if editingStyle == .Delete {
                switch selectedIndex {
                case 0:
                    if indexPath.section == 0 {
                        teacherTeachingList.removeAtIndex(indexPath.row)
                    }else if indexPath.section == 1{
                        teacherEducationList.removeAtIndex(indexPath.row)
                    }
                case 1:
                    teacherProfileCourseList.removeAtIndex(indexPath.row)
                case 2:
                    teacherProfileAchieveList.removeAtIndex(indexPath.row)
                case 3:
                    teacherProfileRecruitList.removeAtIndex(indexPath.row)
                default: break
                }
                tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)
                tableView.reloadData()
            }
    }
    func tableView(tableView: UITableView, titleForDeleteConfirmationButtonForRowAtIndexPath indexPath: NSIndexPath) -> String?
     {
        return "删除"
    }

注：第一个tableView是两个分组的。上述两个代理方法即可实现左滑删除的效果。
