在UITableView上添加 swipe手势

UISwipeGestureRecognizer *recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self 
                                                                                  action:@selector(handleSwipeLeft:)];
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionLeft)];
    [self.tableView addGestureRecognizer:recognizer];
    [recognizer release];

- (void)handleSwipeLeft:(UISwipeGestureRecognizer *)gestureRecognizer
{
    //Get location of the swipe
    CGPoint location = [gestureRecognizer locationInView:self.tableView];
 
    //Get the corresponding index path within the table view
    NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:location];
 
    //Check if index path is valid
    if(indexPath)
    {
        //Get the cell out of the table view
        UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
 
        //Update the cell or model 
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
    }
