像按钮一样快速的火力

在tableViewCell 中，我有likeButton 和unlikeButton。我想要的是当我按下 likeButton 时 - 将数据从单元格保存到 firebase，当我不同时 - 删除

但我有两个问题：

1-- 当我单击 likeButton 时cell == indexPath.row 0 or 1，例如在最后一个或上一个单元格上单击 likeButton

2--当我点击不一样的按钮时，我想删除-但这不起作用

在单元格中我有：

var index: Int?
var cat = ""
var quoteNAme = ""
var quoteNum = ""

  @IBAction func likePressed(_ sender: UIButton) {
         sender.tag = index!
        saveToUser(whereSave: "userLikes", quant: "quantLikes")

        self.likeBtn.isEnabled = false

        let ref = Database.database().reference().child("Цитаты").child("\(cat)").child("\(quoteNAme)").child("\(quoteNum)")
        let keyToPost = ref.childByAutoId().key!
        let updateLikes: [String : Any] = ["peopleWhoLike/\(keyToPost)" : Auth.auth().currentUser!.uid]
        ref.updateChildValues(updateLikes, withCompletionBlock: { (error, reff) in
            if error == nil {
                ref.observeSingleEvent(of: .value, with: { (snap) in
                    if let properties = snap.value as? [String : AnyObject] {
                        if let likes = properties["peopleWhoLike"] as? [String : AnyObject] {
                            let count = likes.count
                            self.likeLabel.text = "\(count)"
                            let update = ["quant" : count]
                            ref.updateChildValues(update)
                            self.likeBtn.isHidden = true
                            self.unlikeBtn.isHidden = false
                            self.likeBtn.isEnabled = true
                        }
                    }
                })
            }
        })
          ref.removeAllObservers()
        }
    }

@IBAction func unlikePressed(_ sender: UIButton) {
        self.unlikeBtn.isEnabled = false
        deleFromUser(whereSave: "userLikes", quant: "quantLikes")

        let ref = Database.database().reference().child("Цитаты").child("\(cat)").child("\(quoteNAme)").child("\(quoteNum)")

        ref.observeSingleEvent(of: .value, with: { (snapshot) in
            if let properties = snapshot.value as? [String : AnyObject] {
                if let peopleWhoLike = properties["peopleWhoLike"] as? [String : AnyObject] {
                    for (id,person) in peopleWhoLike {
                        if person as? String == Auth.auth().currentUser!.uid {
                            ref.child("peopleWhoLike").child(id).removeValue(completionBlock: { (error, reff) in
                                if error == nil {
                                    ref.observeSingleEvent(of: .value, with: { (snap) in
                                        if let prop = snap.value as? [String : AnyObject] {
                                            if let likes = prop["peopleWhoLike"] as? [String : AnyObject] {
                                                let count = likes.count
                                                self.likeLabel.text = "\(count)"
                                                ref.updateChildValues(["quant" : count])
                                            }else {
                                                self.likeLabel.text = "0"
                                                ref.updateChildValues(["quant" : 0])
                                            }
                                        }
                                    })
                                }
                            })

                            self.likeBtn.isHidden = false
                            self.unlikeBtn.isHidden = true
                            self.unlikeBtn.isEnabled = true
                            break

                        }
                    }
                }
            }

        })
        ref.removeAllObservers()
    }

保存和remome功能

func saveToUser(whereSave:String, quant: String) {
        let userUID = Auth.auth().currentUser!.uid
        let ref = Database.database().reference().child("users").child("\(userUID)")

        let keyToPost = ref.childByAutoId().key!
        let mark = "Цитаты/\(cat)/\(quoteNAme)/\(quoteNum)"
        let updateuser: [String : Any] = ["\(whereSave)/\(keyToPost)" : mark]
        ref.updateChildValues(updateuser, withCompletionBlock: { (error, reff) in
            if error == nil {
                ref.observeSingleEvent(of: .value, with: { (snap) in
                    if let properties = snap.value as? [String : AnyObject] {
                        if let likes = properties["\(whereSave)"] as? [String : AnyObject] {
                            let count = likes.count
                            let update = ["\(quant)" : count]
                            ref.updateChildValues(update)
                        }
                    }
                })
            }
        })
        ref.removeAllObservers()
    }

    func deleFromUser(whereSave:String, quant: String){
        let userUID = Auth.auth().currentUser!.uid
        let mark = "Цитаты/\(cat)/\(quoteNAme)/\(quoteNum)"
        let ref = Database.database().reference().child("users").child("\(userUID)")

        ref.observeSingleEvent(of: .value, with: { (snapshot) in

            if let properties = snapshot.value as? [String : AnyObject] {
                if let peopleWhoLike = properties["\(whereSave)"] as? [String : AnyObject] {
                    print("peopleWhoLike= \(peopleWhoLike)")
                    for (id,person) in peopleWhoLike {
                        if person as! String == mark {
                            ref.child("\(whereSave)").child(id).removeValue(completionBlock: { (error, reff) in
                                if error == nil {
                                    ref.observeSingleEvent(of: .value, with: { (snap) in
                                        if let prop = snap.value as? [String : AnyObject] {
                                            print("prop=\(prop)")
                                            if let likes = prop["\(whereSave)"] as? [String : AnyObject] {
                                                let count = likes.count
                                                ref.updateChildValues(["\(quant)" : count])
                                            }else {
                                                ref.updateChildValues(["\(quant)" : 0])
                                            }
                                        }
                                    })
                                }
                            })
                        }
                    }
                }
            }

        })
        ref.removeAllObservers()
    }

在 ViewController 我有：

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "CategoryQuoteCell") as! CategoryQuoteCell
    let tett = indexPath.row
    let quant = quantLike[tett]
    cell.quoteNAme = quoteNAme
    cell.quoteNum = quotenumber[indexPath.row]
    cell.cat = cat
    cell.index = indexPath.row
    cell.likeLabel.text = quant.description
    cell.quoteTF.text = quoteList[tett]

    cell.cellDelegate = self

    for person in self.posts[indexPath.row].peopleWhoLike {
        if person == Auth.auth().currentUser!.uid {

            cell.likeBtn.isHidden = true
            cell.unlikeBtn.isHidden = false

            break

        }
    }
    return cell
}

当像 btn 一样按下时 -it' 工作良好并保存
