iOS实现列表折叠效果

本文实例为大家分享了iOS实现列表折叠效果的具体代码，供大家参考，具体内容如下

实现列表折叠效果其实比较简单，点击列表头部的时候，把返回列表行数设为 0，就是收起列表；再次点击列表头部，显示列表的行数，就展开了列表。

#import "TableDownUpVC.h"
#import "TableViewCell_TableSelect.h"

@interface TableDownUpVC ()
{
 NSMutableDictionary *dicSelet;
 NSArray *arrData;
 NSMutableArray *arrStatus;
 NSInteger selectFlag;

 NSMutableDictionary *dictShow;
}

@property (nonatomic, strong) UIImageView *imgArror;

@end

@implementation TableDownUpVC

- (void)viewDidLoad {
 [super viewDidLoad];
 self.tableView.autoresizingMask = UIViewAutoresizingFlexibleHeight;
 self.title = @"列表折叠效果";

 dictShow = [[NSMutableDictionary alloc] init];
 arrStatus = [[NSMutableArray alloc] init];

 NSDictionary *dict0 = @{@"section":@"头部0",
@"content":@[@{@"title":@"Section0",@"subTitle":@"Row0",@"avator":@"user_default_blue"},
    @{@"title":@"Section0",@"subTitle":@"Row1",@"avator":@"user_default_blue"},
    @{@"title":@"Section0",@"subTitle":@"Row2",@"avator":@"user_default_blue"}]};

 NSDictionary *dict1 = @{@"section":@"头部1",
@"content":@[@{@"title":@"Section1",@"subTitle":@"Row0",@"avator":@"user_default_blue"},
    @{@"title":@"Section1",@"subTitle":@"Row1",@"avator":@"user_default_blue"},
    @{@"title":@"Section1",@"subTitle":@"Row2",@"avator":@"user_default_blue"}]};

 NSDictionary *dict2 = @{@"section":@"头部2",
@"content":@[@{@"title":@"Section2",@"subTitle":@"Row0",@"avator":@"user_default_blue"},
    @{@"title":@"Section2",@"subTitle":@"Row1",@"avator":@"user_default_blue"},
    @{@"title":@"Section2",@"subTitle":@"Row2",@"avator":@"user_default_blue"}]};

 arrData = @[dict0,dict1,dict2];

 dicSelet = [[NSMutableDictionary alloc] init];

 //初始化选中状态(默认都不选择)
 for (NSInteger i=0; i
