指定根視圖:

 

    self.window.rootViewController = [[UINavigationController alloc] initWithRootViewController:[[RootTableViewController alloc] initWithStyle:UITableViewStylePlain]];

 

RootTableViewController.m

 

#import WGModel.h
#import WGCell.h

@interface RootTableViewController ()

- (void)viewDidLoad

    [self.tableView registerClass:[WGCell class] forCellReuseIdentifier:@cell];

}

請求數據:

#pragma mark - Table view data source

自適應高

 

 

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSString *key = self.dataDict.allKeys[indexPath.section];
    NSMutableArray *mutableArray = self.dataDict[key];

    if (model.isShow) {
        return (model.pois.count + 1) * 44;
    } else {
        return 44;
    }
}

點擊cell會走的方法

 

 

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSString *key = self.dataDict.allKeys[indexPath.section];
    NSMutableArray *mutableArray = self.dataDict[key];
    WGModel *model = mutableArray[indexPath.row];
    model.isShow = !model.isShow;
    [self.tableView reloadRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
}

自定義cell

 

 

//.h
#import 
@class WGModel;
@interface WGCell : UITableViewCell

@property (nonatomic, strong) UILabel *aLabel;
@property (nonatomic, strong) UITableView *tableView;


- (void)configureCellWithModel:(WGModel *)model;

- (void)showTableView;
- (void)hiddenTableView;

@end

//.m
#import WGCell.h
#import WGModel.h

@interface WGCell ()

@property (nonatomic, strong) NSMutableArray *dataArray;

@end

@implementation WGCell


- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    if (self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]) {
        self.dataArray = [NSMutableArray array];
        [self addAllViews];

    return self;
}

    self.aLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, 44)];
    self.aLabel.backgroundColor = [UIColor greenColor];
    [self.contentView addSubview:self.aLabel];
    self.tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 44, [UIScreen mainScreen].bounds.size.width, 0) style:UITableViewStylePlain];
    
    self.tableView.delegate = self;
    self.tableView.dataSource = self;
    [self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:@testCell];
//    [self.contentView addSubview:self.tableView];
}

- (void)showTableView
{
    [self.contentView addSubview:self.tableView];
}

- (void)hiddenTableView
{
    [self.tableView removeFromSuperview];
}

- (void)configureCellWithModel:(WGModel *)model
{
    [self.dataArray removeAllObjects];
    self.aLabel.text = model.place[@name];
    
    NSArray *array = model.pois;
    for (NSDictionary *dict in array) {
        NSString *str = dict[@name];
        [self.dataArray addObject:str];
    }
    CGRect frame = self.tableView.frame;
    frame.size.height = 44 * array.count;
    self.tableView.frame = frame;
    [self.tableView reloadData];
    
}


- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return self.dataArray.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@testCell forIndexPath:indexPath];
    NSString *str = self.dataArray[indexPath.row];
    cell.textLabel.text = str;
    return cell;
}

准備一個model類

 

 

//.h
#import 

@interface WGModel : NSObject

@property (nonatomic, assign) BOOL isShow;
@property (nonatomic, strong) NSDictionary *place;
@property (nonatomic, strong) NSArray *pois;

@end


//.m
#import WGModel.h

@implementation WGModel

- (void)setValue:(id)value forUndefinedKey:(NSString *)key
{
    
}

@end

最終效果:
