Answer 1

You need to implement the following method:

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

Answer 2

You have to know the heights of all cells before the tableView:cellForRowAtIndexPath: delegate call which may require you to store heights inside your view controller or some other list.

The function to customise the heights of cells is tableView:heightForRowAtIndexPath:. The default height for a table view is 44 pixels, for reference.

You can find the documentation here.
