You can look at this method:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath

In your case, the code should look like:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
   if (indexPath.section == 1 && indexPath.row == 1) {
      return SPECIAL_HEIGHT;
   }
   return NORMAL_HEIGHT;
}

You can look for more details about the method here

In iOS 8 and above we can use the Dynamic Table View Cell Height.

Using this feature UITableviewCell get its height from its content and We don't need to write heightForRowAtIndexPath

All I have to do in viewDidLoad()

tableView.estimatedRowHeight = 44.0;
tableView.rowHeight = UITableViewAutomaticDimension;

If cell contains uilabel. then apply constraints to uilabel

Make sure you change Label --Lines-- to 0

The cell will grow automatically with content of uilabel:

You can implement the following method to return the height for the row at a given index path:

Have a look at

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath

For the indexpath just check for which row and section and adjust the height accordingly
