可扩展节UITableView IndexPath SWIFT [英] Expandable Sections UITableView IndexPath SWIFT
问题描述
我对编码还很陌生，我只知道Swift.我发现了一些教程可以在表格中生成下拉部分.基本上它将代表电视节目，标题将是季节以及每个季节的情节下拉列表.
Im pretty new to coding, I only know Swift. I have found several tutorials to produce drop down sections in a table. Basically it will represent a TV show, the headers will be the seasons and the drop down list of episodes from each season.
我设法从 https://github.com/fawazbabu/Accordion_Menu
这一切看起来不错，但是我需要能够从下拉菜单中进行选择.我添加了didSelectRowAtIndexPath，并仅以简单的行开始打印.当我选择行，节或单元格时，将返回随机索引路径，可以再次按下同一行并返回不同的值.我认为这只是我添加到该问题中的内容.因此，我在原始代码中添加了didSelectRowAtIndexPath.这有同样的问题.
This all looks good, however I need to be able to select from the drop down items. I have added didSelectRowAtIndexPath with just a simple print of the rows to start with. When I select a row, section or cell, random index paths are returned, the same row can be pressed a second time and return a different value. I thought this was just something I had added to the issue. So I added didSelectRowAtIndexPath to the original code. This has the same issue.
我认为这是因为使用了UIGestureRecogniser以及didSelectRowAtIndexPath.但是我不确定是什么选择.
I assume this is because a UIGestureRecogniser is being used as well as didSelectRowAtIndexPath. But I am not sure what the alternative is.
有人可以告诉我我要去哪里错吗?
Could someone tell me where I am going wrong please?

推荐答案
我不知道为什么需要部分来完成所需的操作，您可以使用普通单元格实现此操作，而无需进行任何复杂操作.您只需要区分子细胞的父细胞即可.
I don't know why you need sections to do it what you want, you can achieve with normal cells, no need to complicate at all. Just differentiating the parent cells of the child cells is all you need.
我在Github中有一个存储库，可以实现所需的内容，而无需使用UITapGestureRecognizer部分.我将尽快尝试将项目更新为更好的性能，并在下拉菜单中增加深度层次.
I have a repository in Github that achieve what you want, without using sections neither UITapGestureRecognizer. As soon as possible I'll try to update the project to better performance and more levels of depth in the dropdown.
您可以达到 AccordionMenu ，并随时发布您需要的任何内容.
You can reach it AccordionMenu , and feel free to post anything you need as issue.
希望这对您有所帮助.
