iOS swift中具有多个和单个选择的下拉表视图？
我有一个过滤器，它是在视图控制器的下拉表视图中完成的。下拉表视图包含三个部分，即第1节、第2节和第3节。第1节和第3节应为单选，第2节应为多选。点击第1节时，它将展开表格视图单元格；点击第2节时，它将展开，第1节将关闭展开 当从每个部分选择选项时，用户应关闭并重新打开过滤器下拉表视图 我有四个问题：iOS swift中具有多个和单个选择的下拉表视图？,ios,swift,xcode,uitableview,Ios,Swift,Xcode,Uitableview,我有一个过滤器，它是在视图控制器的下拉表视图中完成的。下拉表视图包含三个部分，即第1节、第2节和第3节。第1节和第3节应为单选，第2节应为多选。点击第1节时，它将展开表格视图单元格；点击第2节时，它将展开，第1节将关闭展开 当从每个部分选择选项时，用户应关闭并重新打开过滤器下拉表视图 我有四个问题： import UIKit protocol ExpandableHeaderViewDelegate { func toogleSection(header: ExpandableHeaderV
