Using date from array to sort UITableview by date
I have an array with the following information, retrieved from JSON:

I am trying to create the tableview with the startTime (only the date, not the hours and minutes) as the titleForHeaderInSection. The NSMutableArray containing the events is called events
Can anybody help me in the right direction. As it stands now, i am getting data back with no headers, and just the events. I have the following right now, but I am still testing. This at least creates a header called Test
#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;
}
Have edited the code above. It now works, but it is showing the same game every time. As if it always takes the first one, and shows that. I think the problem is in the
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 1;
}
method.

I think you used Uppercase letter in the property Title . In the array it is simply 'title'
Try the below lines of code.
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
return [[events objectAtIndex: section] objectForKey: @"title"];
}
- If it is not working can you please show us the
CalendarModelclass
One main problem of your implementation is , your header will always display first title as header , Since you have only 1 section
If I am rite you need to implement like this
#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;
}

Your json data give me error in http://json.parser.online.fr/
Try this :
- (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"];
}
