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
