Question

Want to populate two NSMutableArrays to 2 Custom Sections of tableView;

I have two NSMutableArrays with events and I want to split them to now and today sections.

For the first section:

I want to remove events from nowEvents Array and place them into my frist section.

EventClass *event = [appDelegate.nowEvents objectAtIndex:indexPath.row];

event.startTime is the start time of my event

event.endTime is the end time of my event

For 2nd section:
Remove the events that are happening now

EventClass *event = [appDelegate.todayEvents objectAtIndex:indexPath.row];

What I’d like to know is numberOfRowsInSection method, how it would look like and cellForRowAtIndexPath (here I’ve tried NSInteger section = [indexPath section]; if (section == 0) { } if (section == 1) {} – but what about if I won’t have an event that is happening now ?)

Answer 1

Something like this should work

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
#warning Potentially incomplete method implementation.
    // Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
#warning Incomplete method implementation.
    // Return the number of rows in the section.
    switch (section) {
        case 0:
            return [appDelegate.nowEvents count];
        case 1:
            return [appDelegate.todayEvents count];    
        default:
            return 0;
    }
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }


    switch (indexPath.section) {
        case 0:
            EventClass *nowEvent = [appDelegate.nowEvents objectAtIndex:indexPath.row];
            //set up cell to display this event
            break;
        case 1:
            EventClass *todayEvent = [appDelegate.todayEvents objectAtIndex:indexPath.row];
            //set up cell to display this event
            break;    
        default:
            break;
    }

    // Configure the cell...

    return cell;
}

If you don’t have an event happening now then your nowEvent array will be empty so in the numberOfRowsInSection will return 0 and therefore the cellForRowAtIndexPath won’t be called as there is nothing to display. Hope this helps.
