Ios 评论系统（类似Facebook）的实施

我正在寻找一种方法来创建一个类似于Facebook的帖子评论部分的评论系统

现在我有这样的结构：

但是我还需要实现回复评论和回复回复回复等等。

要实现与Facebook相同的行为，应该做些什么？

要实现刷到

回复

或

删除

等功能，请使用此库：

对于答复和删除，请执行以下操作：

private func addFuncButtons(to cell: CommentCell, at row: Int) {
  let currentUserId = User.getCurrentUserId()

  if (cell.comment.userId == currentUserId // if its current user comment
     || userId! == currentUserId) // if current user is post author
     && cell.comment.key != "" { // cant delete desc
     cell.rightButtons = [
        MGSwipeButton(title: "", icon: UIImage(named:"delete.png"), backgroundColor: .red) {
           (sender: MGSwipeTableCell!) -> Bool in
           self.removeCell(cell, at: row)
           return true
        },
        MGSwipeButton(title: "", icon: UIImage(named:"reply.png"), backgroundColor: .darkGray) {
           (sender: MGSwipeTableCell!) -> Bool in
           self.replyToUser(with: cell.userNickName.currentTitle!)
           return true
        }
     ]
  } else {
     // add only reply button
     cell.rightButtons = [
        MGSwipeButton(title: "", icon: UIImage(named:"reply.png"), backgroundColor: .darkGray) {
           (sender: MGSwipeTableCell!) -> Bool in
           self.replyToUser(with: cell.userNickName.currentTitle!)
           return true
        }
     ]
  }

  cell.rightSwipeSettings.transition = .rotate3D
}

行动：

private func removeCell(_ cell: CommentCell, at row: Int) {
  removeCellFromTable(cell, at: row)
  removeCellFromDataBase(cell)
}

private func removeCellFromTable(_ cell: CommentCell, at row: Int) {
   comments.remove(at: row)
   tableView.reloadData()
}

private func removeCellFromDataBase(_ cell: CommentCell) {
   Comment.remove(cell.comment, from: post)
}

private func replyToUser(with login: String) {
   newCommentTextField.text = newCommentTextField.text?.appending(" @" + login)
}

像那样
