Try this code for cell size.

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


    NSString *text =@"your String";

    CGSize constraint = CGSizeMake(CellContentWidth - (CellMargin * 2), 20000.0f);

    CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:FontSize] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];

    CGFloat height = MAX(size.height, 44.0f);


    return height + (cellMargin* 2);

}

This code use for cell label Height.

    NSString *text = [arr objectAtIndex:indexPath.row];

    CGSize constraint = CGSizeMake(labelwidth , 20000.0f);

    CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:15] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];

    CGFloat height = MAX(size.height, 44.0f);

    cell.lbl3.frame=CGRectMake(X,Y ,W, height);

Implement the method

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
   //return appropriate value based on IndexPath.row

  UIFont *font = textLabel.font; // use custom label's font
  NSString *myText = @"your text for row at index path";
  CGSize size = [myText sizeWithFont:font forWidth:textLabel.frame.size.width lineBreakMode:UILineBreakModeWordWrap];
  return (size.height+20); //10 pixels space above the textlabel and below 10 pixels space
}

as mentioned in the link you have referred.

Use the following delegate method:

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
   //return appropriate value based on IndexPath.row
}

Within this Method, from the datasource aray, check the length of the string for tht particular row and return the height accordingly.
