我试图创建一个开始时间（只有日期，而不是小时的tableview和分钟）作为titleForHeaderInSection。包含事件的NSMutableArray被称为事件
任何人都可以帮助我走向正确的方向。就目前而言，我正在收回没有标题的数据，只是事件。我现在有以下内容，但我仍在测试。这至少会创建一个名为测试
#pragma mark - table methods
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return events.count;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 1;
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
CalendarModel* event = events[section];
NSString *dato = [[event.time objectAtIndex:0] startTime];
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.dateFormat = @"yyyy-MM-dd'T'HH:mm:ss.SSSzzz";
NSDate *gmtDate = [formatter dateFromString: dato];
formatter.dateFormat = @"dd-MM-yyyy";
dato = [formatter stringFromDate:gmtDate];
return dato;
}
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
CalendarModel* event = events[indexPath.row];
NSString *dato = [[event.time objectAtIndex:0] startTime];
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.dateFormat = @"yyyy-MM-dd'T'HH:mm:ss.SSSzzz";
NSDate *gmtDate = [formatter dateFromString: dato];
formatter.dateFormat = @"HH:mm";
dato = [formatter stringFromDate:gmtDate];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"SportCell" forIndexPath:indexPath];
cell.textLabel.text = [NSString stringWithFormat:@"%@",
event.title
];
cell.detailTextLabel.text = dato;
return cell;
}
已编辑上面的代码首部。它现在可以工作，但每次都会显示相同的游戏。仿佛它总是采取第一个，并表明。我认为问题出在
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 1;
}
方法。

您的JSON数据给我http://json.parser.online.fr/
错误试试这个：
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
CalendarModel* event = events[section]; // i think CalendarModel is a class in which you store yor json data one by one.
return event.Title; // In event class you have to save title;
//return [[events objectAtIndex: section] objectForKey: @"Title"];
}
答
我觉得你的财产标题使用大写字母。 在数组中它只是'标题'
请尝试下面的代码行。
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
return [[events objectAtIndex: section] objectForKey: @"title"];
}
- 如果它不工作，你可以请向我们展示
CalendarModel类
您的实现，你的头会一直显示的第一个标题为标题，既然你的一个主要问题只有1部分
如果我是贵族，你需要像这样实施
#pragma mark - table methods
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return events.count;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 1;
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
return [[events objectAtIndex: section] objectForKey: @"title"];
}
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
CalendarModel* event = events[indexPath.section];
NSString *dato = [[event.time objectAtIndex:0] startTime];
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.dateFormat = @"yyyy-MM-dd'T'HH:mm:ss.SSSzzz";
//formatter.timeZone = [NSTimeZone timeZoneForSecondsFromGMT:3600];
//formatter.calendar = [[NSCalendar alloc]initWithCalendarIdentifier:NSGregorianCalendar];
//formatter.locale = [[NSLocale alloc]initWithLocaleIdentifier:@"en_GB"];
NSDate *gmtDate = [formatter dateFromString: dato];
formatter.dateFormat = @"dd-MM-yyyy HH:mm";
dato = [formatter stringFromDate:gmtDate];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"SportCell" forIndexPath:indexPath];
cell.textLabel.text = [NSString stringWithFormat:@"%@",
event.title
];
cell.detailTextLabel.text = dato;
return cell;
}
这不是一个JSON，我认为他显示了一个NSManagedObjects数组。 – Raj 2013-04-23 06:59:15
