Hi, I have an iphone App that reads the "category" field from the xml file that is a rss feed. The way my App works is that it displays the content of the rss feed in a table view by categories from the xml "category" field.

Im a bit new to tableviews so im a bit lost.

I just have 2 categories on the xml file, one called "Uncategorized" and another called "Promos".

The current code is:

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 2;
}

// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    switch (section) {
		case 0:
         
            return itemsToDisplay.count;
		default:
   
            return itemsToDisplay.count;
	}
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
    
    if(section == 0)
        return @"Promoções";
    else
        return @"Não Categorizados";
}
// 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:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
		cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    }
    
	// Configure the cell.
  
                
                if (indexPath.section == 0) {
                    MWFeedItem *item = [itemsToDisplay objectAtIndex:indexPath.row];
                    if([item.category isEqualToString:@"PROMOS"]){
                        MWFeedItem *item = [itemsToDisplay objectAtIndex:indexPath.row];
                        NSLog(@"ENTRA NO PROMOS______________________________________________________");
                        NSLog(@"item.category = %@--------------------->", item.category);
                    // Process
                        NSString *itemTitle = item.title ? [item.title stringByConvertingHTMLToPlainText] : @"[No Title]";
                        NSString *itemSummary = item.summary ? [item.summary stringByConvertingHTMLToPlainText] : @"[No Summary]";
                        NSLog(@"IMAGE (table View) = %@",item.image);
                   
                        NSURL *url = [NSURL URLWithString:item.image];
                        ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
                        [request setDelegate:self];
                        [request startAsynchronous];
                        NSData * imageData = [NSData dataWithContentsOfURL:url];
                        UIImage * image = [UIImage imageWithData:imageData];
                    // Set
                        cell.imageView.image = image;
                        cell.textLabel.font = [UIFont boldSystemFontOfSize:15];
                        cell.textLabel.text = itemTitle;
                        NSMutableString *subtitle = [NSMutableString string];
                        if (item.date) [subtitle appendFormat:@"%@: ", [formatter stringFromDate:item.date]];
                        [subtitle appendString:itemSummary];
                        cell.detailTextLabel.text = subtitle;
                        NSLog(@"FIM DO PROMOS________________________________________________________");
                    }
                }else if(indexPath.section == 1){
                    MWFeedItem *item = [itemsToDisplay objectAtIndex:indexPath.row];
                    if([item.category isEqualToString:@"Uncategorized"]){
                        NSLog(@"ENTRA NO UNCATEGORIZED_______________________________________________");
                        NSLog(@"item.category = %@--------------------->", item.category);
                    // Process
                        NSString *itemTitle = item.title ? [item.title stringByConvertingHTMLToPlainText] : @"[No Title]";
                        NSString *itemSummary = item.summary ? [item.summary stringByConvertingHTMLToPlainText] : @"[No Summary]";
                        NSLog(@"IMAGE (table View) = %@",item.image);
                    
                        NSURL *url = [NSURL URLWithString:item.image];
                        ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
                        [request setDelegate:self];
                        [request startAsynchronous];
                        NSData * imageData = [NSData dataWithContentsOfURL:url];
                        UIImage * image = [UIImage imageWithData:imageData];
                    // Set
                        cell.imageView.image = image;
                        cell.textLabel.font = [UIFont boldSystemFontOfSize:15];
                        cell.textLabel.text = itemTitle;
                        NSMutableString *subtitle = [NSMutableString string];
                        if (item.date) [subtitle appendFormat:@"%@: ", [formatter stringFromDate:item.date]];
                        [subtitle appendString:itemSummary];
                        cell.detailTextLabel.text = subtitle;
                        NSLog(@"FIM DO UNCATEGORIZED____________________________________________________");
                }
            
		
	}
    return cell;
}

The problem i have is that it displays the same number of cells for both categories and doesnt filter them by Categorie.

Best Regards.
