UITableview , dynamically section & rows - ios

Question

want create a uitableview dynamically with 2 rows in one section
i write this code but i have problem the repeats only 2 first rows in all sections
now i have this row 0,1 -> section 0 , row 0,1 -> section 1 , row 0,1 -> section 2
want read all rows after for example row 0,1 -> section 0 , row 2,3 -> section 1 , row 4,5 -> section 2 -> row 6,7
items = [[NSMutableArray alloc] init];
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{ return items.count/2; }
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{ return 2; }
- (UITableViewCell *)tableView:(UITableView *)tv cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell;
UILabel *label = nil;
cell = [tv dequeueReusableCellWithIdentifier:#"Cell"];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:#"Cell"] autorelease];
label = [[UILabel alloc] initWithFrame:CGRectZero];
[label setLineBreakMode:UILineBreakModeWordWrap];
[label setMinimumFontSize:FONT_SIZE];
[label setNumberOfLines:0];
[label setFont:[UIFont systemFontOfSize:FONT_SIZE]];
[label setTag:1];
label.textColor = [UIColor darkGrayColor];
[label setAlpha:0.8];
cell.backgroundColor = [UIColor whiteColor];
[[cell contentView] addSubview:label];
}
NSString *text = [items objectAtIndex:[indexPath row]];
CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);
CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
if (!label)
label = (UILabel*)[cell viewWithTag:1];
[label setText:text];
[label setFrame:CGRectMake(CELL_CONTENT_MARGIN-5, CELL_CONTENT_MARGIN+30, CELL_CONTENT_WIDTH - ((CELL_CONTENT_MARGIN * 2)+6), MAX(size.height, 44.0f))];
label.backgroundColor = [UIColor clearColor];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
for (UIView *theSubview in [cell.contentView subviews])
{
if([theSubview isKindOfClass:[UIImageView class]])
{
[theSubview removeFromSuperview];
}
}
UIImageView *imv = [[UIImageView alloc]initWithFrame:CGRectMake(128,5, 32, 32)];
imv.image=[UIImage imageNamed:#"0England.png"];
[cell.contentView addSubview:imv];
[imv release];
if (indexPath.row % 2==0) {
UIImageView *img = [[UIImageView alloc]initWithFrame:CGRectMake(-7 ,10, 8, 18)];
img.image=[UIImage imageNamed:#"...."];
[cell.contentView addSubview:img];
[img release];
}
else { }
return cell;
}

You have a problem in your mapping of indexPaths to the rows of your data structure (in this case, your items array). Each section will be numbered from 0 to ceil(n/2) (which, by the way, should be the number of sections, not simply n/2) where n is the number of elements in items.
Each row inside the section will have an indexPath.row of 0 or 1.
Therefore, in order to map from indexPaths back to your items array, you have to do something like this in your cellForRowAtIndexPath function:
NSString *text = [items objectAtIndex:([indexPath section]*2 + [indexPath row])];
