Question

I have some problems with UITableView and sections/rows.
Iam parsing the section names, all row names and row count per section from a xml.

I have 3 NSMutableArrays:

nameArray (with all row names)
sectionArray (all section names)
secCountArray (row count per section)

For the cellForRowAtindexPath to work, do I have to return the rows for the displayed section?
The next step I would do is to build an 2d Array with sections and all rows for each section.

Does anyone knows any better solution?

Here comes the code:

// 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.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}

// Set up the cell
int xmlEntryIndex = [indexPath indexAtPosition: [indexPath length] -1];

//???
cell.textLabel.text = [[theParser.nameArray objectAtIndex: 1]valueForKey:@"name"];


return cell;
}

Thanks!

You could have one array for the whole table view. The array contains arrays for every section. Then the cellForRowAtIndexPath could look like:

- (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.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    }

    [[cell textLabel] setText: [[[myArray objectAtIndex: indexPath.section] objectAtIndex: indexPath.row]];
    return cell;
}

I hope this help you in your problem.

Edit: With the modern Objective-C and ARC I would write this as

- (void)viewDidLoad {
    ....
    [self.tableView registerClass:[MyCellClass class] forCellReuseIdentifier:kMyCellIdentifier];
} 
...
- (UITableViewCell*)tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath {    

    MyCellClass *cell = [tableView dequeueReusableCellWithIdentifier:kMyCellIdentifier forIndexPath:indexPath];

    cell.textLabel.text = myArray[indexPath.section][indexPath.row];

    return cell;
}
