我正在用标题部分显示类似消耗性表格视图的数据。标头显示正常。但是当我显示行时。 （就像产品中的5个插件一样，数据显示在消耗性的Tableview中，具有相同类型名称标题的每一行）。我正在附上屏幕截图。显示什么类型的数据。
图像数据显示为：https://imgur.com/a/JXqUbJD
我正在附上我正在使用的当前代码。我已经尝试了太多次了，但是效果不佳。

答案 0 :(得分：1)
您应该在课程override func prepareForReuse()内致电CollapsibleTableViewHeader。
override func prepareForReuse() {
super.prepareForReuse()
//TODO: set default values
}
您能提供CollapsibleTableViewHeader类的代码吗？
