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


    CGSize maxSize = CGSizeMake(max_size);
    CGSize cellSize = [yourString 
                       sizeWithFont:[UIFont systemFontOfSize:15]
                       constrainedToSize:maxSize
                       lineBreakMode:UILineBreakModeWordWrap];
    return cellSize.height;

}

Consider my implementation:

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

switch (theSection) {
    case 0:
        if (indexPath.row ==6) //the row you need to check for height (if any)

        {

            if([yourString length]<=35) // if less than 35 chars, just return a basic size of 50
            {
                return 50;
            }

            CGSize detailSize = [yourString sizeWithFont:[UIFont systemFontOfSize:20]constrainedToSize:CGSizeMake(270, 4000)lineBreakMode:UILineBreakModeWordWrap];

            return detailSize.height;
        }

hope this helps to help you understand that you can take a look at “sizeWithFont” to understand what it does to return the size.

You need to use the method tableView:heightForRowAtIndexPath:in your UITableViewDelegate to return the row height. Note that this method should be very fast if you have more than a few rows, as it will be called for each row of the table, and not just for visible rows.
