So what you essentially need is to get the cell from swipe gesture on the table? Right.You dont need to know the indexPath. First define swipe on the tableView like so -

UISwipeGestureRecognizer *showExtrasSwipe = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(cellSwipe:)];
showExtrasSwipe.direction = UISwipeGestureRecognizerDirectionRight;
[tableView addGestureRecognizer:showExtrasSwipe];
[showExtrasSwipe release];

After this when the actual swipe happens you need to put handler to it. For that try this-

-(void)cellSwipe:(UISwipeGestureRecognizer *)gesture
{
    CGPoint location = [gesture locationInView:tableView];
    NSIndexPath *swipedIndexPath = [tableView indexPathForRowAtPoint:location];
    UITableViewCell *swipedCell  = [tableView cellForRowAtIndexPath:swipedIndexPath];

    //Your own code...
}

So what we have done is first attach a SwipeGestureRecognizer to the UITableView (not the UITableViewCell). After that when the swipe occurs on the UITableView, I first get the co-ordinates of where the gesture occurred in the UITableView. Next, using this coordinates I get the IndexPath of the row of where swipe occurred in the UITableView. Finally using the IndexPath I get the UITableViewCell. Simple really..

Note: I have been asked this far too many times. So adding this explanation of why I used SwipeGestureRecognizer on the UITableView and not on each individual UITableViewCell.

I could have attached SwipeGestureRecognizer to each UITableViewCell. I did not do that since I would have had to attach a separate SwipeGestureRecognizer for each cell. So If I had 1000 cells in my UITableView I would have had to create 1000 SwipeGestureRecognizer objects. This is not good. In my above approach I just create one SwipeGestureRecognizer and thats it.

of course it did. This particular piece of code has already seen millions of swipes ! — Srikar Appalaraju, Aug 24 '11 at 04:50
I think you need to changed the pinchedIndexPath to swipedIndexPath — DenTheMan, Jul 12 '12 at 23:24
I assign this code in my tableview which is a implementation of the horizontal table view style (tableview within a tableview) but the swipe does not fire? The did select cell works so I know I am putting code in for right table....but no joy? — user7865437, Aug 22 '12 at 14:33

If you are trying to implement 'swipe to delete' (swipe in the horizontal direction), you do not need to re-invent the wheel. Simply uncomment the method commitEditingStyle:forRowAtIndexPath: in your UITableViewController delegate.

Did you checked this source code? : https://github.com/thermogl/TISwipeableTableView

That really might help you, this is a full implementation of a "swipeable" tableview...
