Declaration声明

     commitEditingStyle editingStyle: UITableViewCellEditingStyle,
      forRowAtIndexPath indexPath: NSIndexPath)
OBJECTIVE-C
- (void)tableView:(UITableView *)tableView
commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
forRowAtIndexPath:(NSIndexPath *)indexPath
Parameters参数
tableView   
The table-view object requesting the insertion or deletion.
editingStyle   
The cell editing style corresponding to a insertion or deletion requested for the row specified by indexPath. Possible editing styles are UITableViewCellEditingStyleInsert or UITableViewCellEditingStyleDelete.
indexPath   
An index path locating the row in tableView.
Discussion
When users tap the insertion (green plus) control or Delete button associated with a UITableViewCell object in the table view, the table view sends this message to the data source, asking it to commit the change. (If the user taps the deletion (red minus) control, the table view then displays the Delete button to get confirmation.) The data source commits the insertion or deletion by invoking the UITableView methods insertRowsAtIndexPaths:withRowAnimation: or deleteRowsAtIndexPaths:withRowAnimation:, as appropriate.

To enable the swipe-to-delete feature of table views (wherein a user swipes horizontally across a row to display a Delete button), you must implement this method.

You should not call setEditing:animated: within an implementation of this method. If for some reason you must, invoke it after a delay by using the performSelector:withObject:afterDelay: method.
