Question

I have a big problem with an UITableView, I want to use a label inside the cell, so I use this method for do it

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

// If the indexPath is less than the numberOfItemsToDisplay, configure and return a normal cell,
// otherwise, replace it with a button cell.

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
else {

}

if (indexPath.section == 0) {

    elemento = [array objectAtIndex:indexPath.row];

    UILabel *labelTitle = [[UILabel alloc] initWithFrame:CGRectMake(100, 0, 220, 30)];
    labelTitle.text = [elemento objectForKey:@"Titolo"];
    labelTitle.backgroundColor = [UIColor clearColor];
    labelTitle.textColor = [UIColor whiteColor];
    [cell addSubview:labelTitle];

} else {

    UILabel *labelTitle = [[UILabel alloc] initWithFrame:CGRectMake(100, 0, 220, 30)];
    labelTitle.text = @"Read More";
    labelTitle.backgroundColor = [UIColor clearColor];
    labelTitle.textColor = [UIColor whiteColor];
    [cell addSubview:labelTitle];

}


return cell;

}

in this way I can see all the data on my table, but the label are overlap, than I try to use this method

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

// If the indexPath is less than the numberOfItemsToDisplay, configure and return a normal cell,
// otherwise, replace it with a button cell.

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];

    if (indexPath.section == 0) {

        elemento = [array objectAtIndex:indexPath.row];

        UILabel *labelTitle = [[UILabel alloc] initWithFrame:CGRectMake(100, 0, 220, 30)];
        labelTitle.text = [elemento objectForKey:@"Titolo"];
        labelTitle.backgroundColor = [UIColor clearColor];
        labelTitle.textColor = [UIColor whiteColor];
        [cell addSubview:labelTitle];

    } else {

        UILabel *labelTitle = [[UILabel alloc] initWithFrame:CGRectMake(100, 0, 220, 30)];
        labelTitle.text = @"Read More";
        labelTitle.backgroundColor = [UIColor clearColor];
        labelTitle.textColor = [UIColor whiteColor];
        [cell addSubview:labelTitle];

    }

}
else {

}

return cell;

}

the label are OK but in this case I can see on my table only 5 data, and this 5 data are repeat for some time…

For example if in the first case on my table I can see: 1,2,3,4,5,6,7,8,9,10,…
in the second case I seee: 1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,…

where is the problem?

Answer 1

add this code

  for (UIView *view in [cell.contentView subviews]) 
    {
        [view removeFromSuperview];
    }

before

if (indexPath.section == 0) {

elemento = [array objectAtIndex:indexPath.row];

UILabel *labelTitle = [[UILabel alloc] initWithFrame:CGRectMake(100, 0, 220, 30)];
labelTitle.text = [elemento objectForKey:@"Titolo"];
labelTitle.backgroundColor = [UIColor clearColor];
labelTitle.textColor = [UIColor whiteColor];
[cell addSubview:labelTitle];

Currently you add a label to the cell and the next time the cell is reused..the label is still there and you add a label on top of it.
