可扩展部分UITableView IndexPath SWIFT

Question

我对编码很新,我只知道Swift.我找到了几个教程来在表格中生成下拉部分.基本上它将代表一个电视节目,标题将是季节和每个季节的剧集下拉列表.

我设法通过https://github.com/fawazbabu/Accordion_Menu完美地满足我的需求

这一切看起来都不错,但是我需要能够从下拉项中进行选择.我添加didSelectRowAtIndexPath了一个简单的行打印开头.当我选择行,节或单元格时,会返回随机索引路径,可以再次按下同一行并返回不同的值.我认为这只是我在问题中添加的内容.所以我添加didSelectRowAtIndexPath了原始代码.这有同样的问题.

我假设这是因为UIGestureRecogniser正在使用a 和didSelectRowAtIndexPath.但我不确定替代方案是什么.

有人能告诉我哪里出错了吗？

我不知道为什么你需要用你喜欢的部分去做,你可以用普通细胞来实现,根本不需要复杂化.只需区分子细胞的亲本细胞即可.

我在Github有一个存储库,可以实现你想要的,而不使用任何部分UITapGestureRecognizer.我会尽快更新项目,以便在下拉列表中更好地提升性能和更深层次.

您可以使用AccordionMenu ,并随时发布您需要的任何问题.

我希望这对你有帮助.
