- tableView
- Table view.
- indexPath
- Location of the row.
The height of the row (in points) as a float.
This method allows rows to have different heights (for example, rows that contain a variable number of text lines). If this method is implemented, it overrides the UITableView.RowHeight property set on the table view, for the row at indexPath.
There are performance implications to using this method instead of UITableView.RowHeight: every time a table view is displayed it calls this method for each of its rows. This can result in poor performance when the table has a large number of rows (for example, 1000 rows or more).
