swift - 如何从 Firestore 中检索值以更改每个监听项的表格单元格中按钮的文本？

Question

我有一个 tableview，其中有列表项，每个单元格都有一个按钮，我想根据从 firestore 检索到的 bool 值来修复按钮的文本和颜色，每个单元格的按钮都有特定的文本和颜色基于只有值，我知道在 swift 中为按钮设置文本和颜色的语法，我只是不能根据 firestore 的值来做，下面是代码

获取列表的代码，关注的值为checkl1value

func getComments() {

      //print(postId + "received")
        let commentsRef = Firestore.firestore().collection("posts").document(postId).collection("comments")

        commentsRef.getDocuments { (snapshot, error) in

            if let error = error {

                print(error.localizedDescription)

            } else {

                if let snapshot = snapshot {

                    for document in snapshot.documents {


                        let data = document.data()
                        let username = data["comment_author_username"] as? String ?? ""
                        let comment = data["comment_author_comment"] as? String ?? ""
                        let spinnerC = data["comment_author_spinnerC"] as? String ?? ""
                        let fullname = data["comment_author_fullname"] as? String ?? ""
                        let email = data["comment_author_email"] as? String ?? ""
                        let commentUserImageUrl = data["comment_user_image"] as? String ?? ""
                        let commentuser_id = data["comment_author_id"] as? String ??  ""
                        self.checkl1value  = data["l1"] as? DarwinBoolean


                        let newComment = Comment(_documentId: document.documentID, _commentAuthorUsername: username, _commentAuthorFullName: fullname, _commentAuthorComment: comment, _commentUserImage: commentUserImageUrl, _commentAuthorSpinnerC: spinnerC, _commentAuthorId:commentuser_id )
                        self.comments.append(newComment)

                    }
                    self.tableView.reloadData()
                }
            }
        }
    }

cellForRowAt 代码

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "CommentCell", for: indexPath) as! CommentCell


        cell.commentLikebutton.tag = indexPath.row
        cell.commentLikebutton.addTarget(self, action: #selector(likeaction1(_:)), for: .touchUpInside)


        if checkl1value == true {
        cell.commentLikebutton.setTitle("Text1", for: .normal)
        //  cell.commentLikebutton.backgroundColor = UIColor(red: 17.0/255.0, green: 119.0/255.0, blue: 151.0/255.0, alpha: 1.0)
            cell.commentLikebutton.backgroundColor = UIColor.red
            //cell.commentLikebutton.backgroundColor = UIColor?.red()
        }
        else{
            cell.commentLikebutton.setTitle("Text2", for: .normal)

        }


            cell.set(comment: comments[indexPath.row])

        return cell


    }

Answer 1

在cellForRowAt的顶部添加这样的东西

let thisComment = self.comments[indexPath.row]
let checkl1value = thisComment.checkl1value
