CGSize cellSize = [pppp sizeWithFont:[UIFont systemFontOfSize:14]
constrainedToSize:maxSize lineBreakMode:NSLineBreakByWordWrapping];
//this will return correct height for text
return cellSize.height+150;
}

{
pppp=[postText objectAtIndex:indexPath.row];
CGSize maxSize = CGSizeMake(280, MAXFLOAT);//set max height

hope this helps.
#interface ViewController ()
{
int currentselection;
int cellno;
UITableView *table;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// do things with your cell here
// set selection
cellno = indexPath.row;
}
-(void)buttonpressed
{
currentselection = cellno;
[table beginUpdates];
[table endUpdates];
}
-(float)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
int rowHeight;
if ([indexPath row] == currentselection) {
rowHeight = 200;
} else rowHeight = 100;
return rowHeight;
}
