Label's frame size does not change in tableView cell - ios

Question

I am working in storyboard. I have View Controller inherited from tableViewVC. In that vc I have cells with one or 2 lines of text. If I have one line, I just assign text to a custom textLabel in custom Cell. If I have 2 lines, I resize the labels frame. But it does not work when the table is loaded. I can see my resized labels in cell only after I scroll tableView up/down. How can I fix it?
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
OptionItem *item = _currentOptionsList[indexPath.row];
static NSString *CellIdentifier = #"OptionSimpleCellIdentifier";
OptionSimpleCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
cell.titleLabel.text = item.title;
cell.haveDetail = item.haveDetailItems;
cell.selectedSimpleOption = item.simpleSelected;
if (item.haveSelectedDetailItem)
{
cell.detailLabel.text = [item.detailItems[item.indexOfSelecteDetaildItem] title];
} else {
cell.detailLabel.text = nil;
cell.detailImageView.image = nil;
}
CGFloat textHeight = [Calculatons getLabelHeightForText:item.title andWidth:225 withFont:kFontListCell withMaxHeight:0];//19 - 39
CGRect rect = cell.titleLabel.frame;
NSLog(#"textHeight = %f cell.height = %f titleLabel.height %f \n",textHeight, cell.frame.size.height, cell.titleLabel.frame.size.height);
if (textHeight > 21)
{
rect.size.height = 41;
cell.titleLabel.frame = rect;
}
//nothing of this not works
[cell.titleLabel layoutIfNeeded];
[cell.titleLabel setNeedsLayout];
[cell.titleLabel setNeedsUpdateConstraints];
[cell.titleLabel setNumberOfLines:0];
return cell;
}

After the first screen, i push the VS. second screen is what is shown after i scroll the table up and down.
I need second screen as a result after i push VC.

try using this earlier in the code, right after the cell is initialised instead of after the value is set to the label.
CGFloat textHeight = [Calculatons getLabelHeightForText:item.title andWidth:225 withFont:kFontListCell withMaxHeight:0];//19 - 39
CGRect rect = cell.titleLabel.frame;
NSLog(#"textHeight = %f cell.height = %f titleLabel.height %f \n",textHeight, cell.frame.size.height, cell.titleLabel.frame.size.height);
if (textHeight > 21)
{
rect.size.height = 41;
cell.titleLabel.frame = rect;
}
