接上次分享的自定义cell进行了优化:http://blog.csdn.net/qq_31810357/article/details/49611255

指定根视图:

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

RootTableViewController.m

#import "WGModel.h"
#import "WGCell.h"

@interface RootTableViewController ()

@property (nonatomic, strong) NSMutableDictionary *dataDict;

@end

@implementation RootTableViewController

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.dataDict = [NSMutableDictionary dictionary];

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

请求数据:

- (void)loadDataAndShow
{
    NSURL *url = [NSURL URLWithString:@"http://api.breadtrip.com/trips/2387133727/schedule/"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {

        if (data != nil) {
            NSArray *array = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];
            for (NSDictionary *dict in array) {
                NSString *key = dict[@"date"];
                NSArray *placesArray = dict[@"places"];
                NSMutableArray *mutableArray = [NSMutableArray array];
                for (NSDictionary *placesDict in placesArray) {
                    WGModel *model = [[WGModel alloc] init];
                    [model setValuesForKeysWithDictionary:placesDict];
                    model.isShow = NO;
                    [mutableArray addObject:model];
                }
                [self.dataDict setObject:mutableArray forKey:key];
            }
            [self.tableView reloadData];
        }

    }];
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return self.dataDict.allKeys.count;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    NSString *key = self.dataDict.allKeys[section];
    return [self.dataDict[key] count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    WGCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell" forIndexPath:indexPath];

    NSString *key = self.dataDict.allKeys[indexPath.section];
    NSMutableArray *mutableArray = self.dataDict[key];
    WGModel *model = mutableArray[indexPath.row];
    [cell configureCellWithModel:model];

    if (model.isShow == YES) {
        [cell showTableView];
    } else {

        [cell hiddenTableView];
    }

    return cell;
}

自适应高

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSString *key = self.dataDict.allKeys[indexPath.section];
    NSMutableArray *mutableArray = self.dataDict[key];
    WGModel *model = mutableArray[indexPath.row];
    if (model.isShow) {
        return (model.pois.count + 1) * 44;
    } else {
        return 44;
    }
}

点击cell会走的方法

- (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];
}

自定义cell

//.h
#import <UIKit/UIKit.h>
@class WGModel;
@interface WGCell : UITableViewCell<UITableViewDataSource, UITableViewDelegate>

@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;
}

- (void)addAllViews
{
    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;
}

准备一个model类

//.h
#import <Foundation/Foundation.h>

@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
