【问题描述】：

我如何编辑或更新数据库使用解析的数据。 如何从我知道的单元格中删除日期，代码：

override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath)      
if editingStyle == .delete 
                        // Delete the row from the data source
                        let query = PFQuery(className: "requests")
                        let currReceipt = self.data[indexPath.row]
                        query.whereKey("objectId", equalTo: currReceipt.objectId!)
                        query.findObjectsInBackground(block:  (objects, error) in
                            if error != nil 
                                self.alert(message: "We could not delete the receipt", title: "Oops! Something went wrong number 1!")
                            else
                                for object in objects!
                                    self.data.remove(at: indexPath.row)
                                    object.deleteInBackground()
                                    self.tableView.reloadData()
                                    self.alert(message: "Successfully delete from open task list", title: "Task done")
                                
                            
                        )
                     

我可以使用相同的函数来更新每个单元格的数据吗？ 所以我想要这样的东西：

【参考方案1】：

试试这个。

    let query = PFQuery(className: "requests")
    let currReceipt = self.data[indexPath.row]
    query.whereKey("objectId", equalTo: currReceipt.objectId!)
    query.findObjectsInBackground(block:  (objects, error) in
    if error != nil 
          self.alert(message: "We could not delete the receipt", title: "Oops! Something went wrong number 1!")
    
    else             
       //UPDATE OBJECT
       object["agestart"] = self.fromAge.text
       object["ageend"] = self.toAge.text
       object["location"] = self.location.text
       object.saveInBackground(block:  (success, error) in 
           if error != nil 
               self.alert(message: "Error while updating object", title: "Oops! Something went wrong number 1!")
           
           else 
                self.tableView.reloadData()
           )
          

【讨论】：

@Andrew，但正如我所见，您的问题代码有删除代码。

请问如何编辑数据，和删除日期一样的原理

【参考方案2】：

试试这个客户滑动：

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? 
    let delete = UITableViewRowAction(style: .destructive, title: "Delete")  (action, indexPath) in
        // delete item at indexPath
    

    let update = UITableViewRowAction(style: .normal, title: "Update")  (action, indexPath) in
        // update item at indexPath
    

    update.backgroundColor = UIColor.grey

    return [delete, update]
