Question

I have a grouped UITableView where not all sections may be displayed at once, the table is driven by some data that not every record may have. My trouble is that the records that don’t have certain sections show up as blank spaces in the table.
There are no footers/headers. Anything I’ve missed?

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return [self getRowCount:section];
}


// Customize the appearance of table view cells.
- (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] autorelease];
}

cell.textLabel.text = [NSString stringWithFormat:@"section: %d row: %d",indexPath.section,indexPath.row];
// Configure the cell...

return cell;
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    
    float height = 0.0;
    
    if([self getRowCount:indexPath.section] != 0){
        height = kDefaultRowHeight;
    }
    
    return height;
    
}

Answer 1

In the above screenshot, is your numberOfSectionsInTableView: method returning a value of 5? And then is your getRowCount: method (called from numberOfRowsInSection:) returning a value of 0 for those “missing” sections (e.g. 1, 3 and 4)?

If you don’t want gaps in between, the likely solution is to only declare the number of sections you want to be visible. In your example above, you’d only want to return value of 3 from numberOfSectionsInTableView:.
