如何在ios中单击特定标题时显示可扩展列表

我只想在单击标题部分“2”时显示可展开列表。为此，我从一些地方编辑了这段代码

这里我的主要要求是，当我单击标题部分“2”时，我想加载我自己的数组列表数据，比如（当我单击标题部分2时，arrayforpool=“hai”、“how”、“fine”数据）

#导入“ShowList.h”
#导入“MFSideMenu.h”
#导入“ViewController.h”
@接口显示列表（）{
NSString*imgUrlStr；
UIImageView*imgNew；
UILabel*usrNameLbl；
NSString*usrName；
UIViewController*demoViewController；
UIColor*bg_颜色；
NSMUTABLEARRY*imageArr；
布尔是第一次跑步；
UIImageView*用户图像；
NSMutableArray*arrayforpool；
NSArray*截面标题雷；
NSArray*子列表；
}
@结束
@实现展示列表
