当其他单元格的动画结束时，单元格中的动画停止

如何解决当其他单元格的动画结束时，单元格中的动画停止

我的TableViewCells中的动画出现问题。每当有人越过列表中的项目时，进度条会在4秒钟内从0.0动画到1.0：

func startAnimation() {
        let generator = UIImpactFeedbackGenerator(style: .medium)
        generator.impactOccurred()
        
        if items![indexRow!].checked {
            self.delegate?.changeButton(state: false,indexSection: indexSection!,indexRow: indexRow!,itemID: itemID!)
            self.progressBar.setProgress(0.0,animated: false)
            self.checkBoxOutlet.setBackgroundImage(#imageLiteral(resourceName: "checkBoxOUTLINE "),for: .normal)
        } else {

            self.checkBoxOutlet.setBackgroundImage(#imageLiteral(resourceName: "checkBoxFILLED "),for: .normal)
            self.tempState = true
            UIView.animate(withDuration: 4.0,animations: {
                self.progressBar.setProgress(1.0,animated: true)
          }) { (finished: Bool) in
            
                self.workItem = DispatchWorkItem {
                    self.delegate?.changeButton(state: true,indexSection: self.indexSection!,indexRow: self.indexRow!,itemID: self.itemID)
                }
                
                DispatchQueue.main.asyncAfter(deadline: .now() + 3.3,execute: self.workItem!)
            
            
            }
        }
    }

这有效，动画效果很好。但是，每当彼此快速检查多个项目时，当触发的第一个动画完成时，动画就会停止。 Here is a screenrecord of the issue.

如您所见，有两个主要问题：

1. 其他单元格的动画突然停止
2. 不应该删除的单元格将被删除。

我怀疑问题在于触发的委托方法，而不是此处的动画。这是我的委托方法（用于更新Firestore中的数据）：

func changeButton(state: Bool,indexSection: Int?,indexRow: Int?,itemID: String?) {
    if let indexSection = indexSection,let indexRow = indexRow {
        sections[indexSection].items[indexRow].checked = state
    }
    
    let generator = UIImpactFeedbackGenerator(style: .light)
    generator.impactOccurred()
    
    if let itemID = itemID {
        let itemRef = db.collection(K.FStore.lists).document(currentListID!).collection(K.FStore.sections).document("\(indexSection!)").collection(K.FStore.items).document(itemID)
        
        if sections[indexSection!].items[indexRow!].checked {
            itemRef.updateData([
                K.Item.isChecked: true,K.Item.checkedBy: currentUserID!,K.Item.dateChecked: Date()
            ]) { err in
                if let err = err {
                    print("Error writing document: \(err)")
                } else {
                    print("Document successfully written!")
                    
                    
                    
                }
                
                if let indexSection = indexSection,let indexRow = indexRow {
                    if self.sections[indexSection].items != nil {
                        let item = self.sections[indexSection].items[indexRow]
                        
                        let itemRef = self.db.collection(K.FStore.lists).document(self.currentListID!).collection(K.FStore.sections).document("\(indexSection)").collection(K.FStore.items).document(item.itemID!)
                        
                        itemRef.getDocument { (document,error) in
                            if let document = document,document.exists {
                                
                                
                                // Get the properties of the item
                                let name = document.data()?[K.Item.name] as? String
                                let uid = document.data()?[K.Item.uid] as? String
                                let category = document.data()?[K.Item.categoryNumber] as? Int
                                let isChecked = document.data()?[K.Item.isChecked] as? Bool
                                let dateCreated = document.data()?[K.Item.date] as? Date
                                let dateChecked = document.data()?[K.Item.dateChecked] as? Date
                                let checkedBy = document.data()?[K.Item.checkedBy] as? String
                                
                                self.db.collection(K.lists).document(self.currentListID!).collection(K.FStore.sectionsChecked).document("\(category!)").collection(K.FStore.items).addDocument(data: [
                                    K.Item.name: name,K.Item.isChecked: isChecked,K.Item.categoryNumber: category,K.Item.date: dateCreated,K.Item.dateChecked: dateChecked,K.Item.checkedBy: checkedBy,K.Item.uid: uid,K.Item.dateDeleted: Date()
                                ]) { err in
                                    if let err = err {
                                        print("Error adding document: \(err)")
                                    } else {
                                       let cell = self.tableView.cellForRow(at: IndexPath(item: indexRow,section: indexSection)) as? TaskCell
                                        
                                        if let cell = cell {
                                            cell.progressBar.setProgress(0.0,animated: false)
                                        }
                                        
                                        // If successful,delete the item in the normal collection
                                        itemRef.delete() { err in
                                            if let err = err {
                                                print("Error removing document: \(err)")
                                            } else {
                                                print("Document successfully removed!")
                                            }
                                        }
                                    }
                                }
                            }
                        }
                    }
                }
            }
        } else {
            itemRef.updateData([
                K.Item.isChecked : false
            ]) { err in
                if let err = err {
                    print("Error writing document: \(err)")
                } else {
                    print("Document successfully written!")
                }
            }
        }
    }
}

这与单元格的刷新有关吗？在这一点上我很迷茫，不知道我在做什么错。

如果有人可以帮助我，那将是非常棒的。
