Calculate the table's contentSize.height with custom cells of different types iphone

Question

In my application , the tableview is having different types of custom cells with different heights. I want to put a view below this tableView, for which I need to calculate

Answer 1

If you've implemented your own custom cells, then you've probably already implemented this function in your table delegate:

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

Just iterate through your rows, calling this function for each one, and sum up the result.
