接上次分享的自定义cell进行了优化:
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:@""];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

环境不会改变，解决之道在于改变自己。
