我在一个表视图中有两种不同类型的表视图单元格。第一个单元格将原始评论打印到帖子,第二个单元格将评论打印到另一个评论。当前,tableview以不特定的顺序打印出所有正确的单元格。但是,我想按特定顺序打印单元格。我希望包含对另一个评论的评论的单元格出现在要评论的评论下方。

彼此关联的注释具有相同的“ id”,我将如何组织单元格,以便将主注释的注释列在原始注释的下面。谢谢
答案 0 :(得分:1)
您可以创建一个Comment自定义对象类,该对象类将包含一组子注释和主注释,以正确地排列或管理您的数据结构。之后,您可以在表格视图单元格中正确使用它。 好的,例如,您可以具有以下数据结构。
创建一个注释类:
class Comment {
comment_id
content
post_id
reply_to
}
现在为您的表格视图再创建一个类:
class CommentTableDataModel {
var mainComment: Comment // Of type Comment class
var replies: [Comment] // Array of type Comment class for sub comments
}
因此,现在只需遍历您的Firebase Comments数组,并准备类型为'CommentTableDataModel'对象的数组列表作为表的数据源。因此,最后您将得到一个数组类型为“ CommentTableDataModel”的对象,每个类型为“ CommentTableDataModel”的对象都包含主要的注释信息以及与此相关的回复信息列表,您可以使用它来管理数据。
