How to adjust UITableView's height based on UILabel's height?

Question

I'm having a UITableView. In that I have a single label. I am doing following for label:

Set number of lines to zero
Set top space to container margin
Set bottom space to container margin

My contents for UILabel may vary, some time it may have 3 lines, some times 10 lines etc. My problems is it displays only 2 rows. How to adjust the height of cell so that UILabel will show the whole contents.

Thanks in advance.

You should set numberoflines to 0. Provide either leading & trailing space constraints for your label or fixed width constraint along with top & bottom space constraints. Then use tableView.estimatedRowHeight = 44.0 tableView.rowHeight = UITableViewAutomaticDimension

Thank you it works but why should I set estimatedRowHeight?. – e.k Dec 21 '16 at 05:39

It will calculate your height depending on the autolayout constraints and label size. – Maulik Bhuptani Dec 21 '16 at 05:41
estimatedRowHeight : This will be the minimum height of you row, if AutomaticDimension failed to calculate height then your row height will be set to 44.0 – Devang Tandel Dec 21 '16 at 05:50

set your label's constraint with cell like top bottom leading and trailing, set number of line for labels to zero and line break mode to word wrap. now place this two tableView methods to calculate cell height dynamically.

For Swift 3.0

func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

for Objective C

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
   return UITableViewAutomaticDimension;
}

-(CGFloat)tableView:(UITableView *)tableView estimatedHeightForRowAtIndexPath:(NSIndexPath *)indexPath
{
   return UITableViewAutomaticDimension;
}

so it will take cell size dynamically as you want.

hope this will help you.
