indexPath
An index path locating the row in tableView.

Discussion of [UITableView tableView willBeginEditingRowAtIndexPath]
This method is called when the user swipes horizontally across a row; as a consequence, the table view sets its editing property to YES (thereby entering editing mode) and displays a Delete button in the row identified by indexPath. In this "€œswipe to delete"€ mode the table view does not display any insertion, deletion, and reordering controls. This method gives the delegate an opportunity to adjust the application'€™s user interface to editing mode. When the table exits editing mode (for example, the user taps the Delete button), the table view calls tableView:didEndEditingRowAtIndexPath:.

Note: A swipe motion across a cell does not cause the display of a Delete button unless the table view'€™s data source implements the tableView:commitEditingStyle:forRowAtIndexPath: method.
