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;
     }
 }
