iOS中 自定义cell升级版 (高级)

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
