Parse Swift UITableView Accessory

Question

我有以下代码，现在我正在尝试实现UITableView的附件。所有数据都来自 Parse，即使有教程帮助如何做普通配件，如果我从像 Parse 这样的在线数据库获取数据，我找不到一个真正教如何做到这一点的教程。

从外观上看，您正在尝试将数据传递到详细信息视图，在这种情况下，假设您已经在 detailView 中定义了正确的 indexPath 和变量，您应该执行类似的事情。

  override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
            if let identifier = segue.identifier
            {
                switch identifier
                {
                    doctor "TodoctorDetail":
                        let productDetailVC = segue.destinationViewController as! doctorDetail
                    if let indexPath = self.tableView.indexPathForCell(sender as! UITableViewCell)
                    {
                       // Assuming you have the proper indexPath defined here for the selected cell and that you have these three values already defined in your productDetailVC
                      productDetailVC.doctorName = doctorName[indexPath.row]
                      productDetailVC.doctorContent = doctorContent[indexPath.row]
                      productDetailVC.doctorRate = doctorRating[indexPath.row]
                    }

                default: break
                }
            }ˍ
        }
