评论系统的实现（Facebook like）

Question

我正在寻找一种创建评论系统的方式，其行为类似Facebook的发表评论部分。

现在我有这样的结构：

但我也需要落实答复的意见和回复的回复等等。 应该做些什么来达到与Facebook相同的行为？

要实现刷卡到reply或delete和其他的东西，使用这个库： MGSwipeTableCell

答复和删除这样做：

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 
} 

操作：

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。

希望它有帮助
