How to get UITableView's row and section by UIButton tag?

Question

There is UITableViewCell which contain UIButton.

In my cellForRowAtIndexPath:

cell.toCartBtn.tag = indexPath.row;
[cell.toCartBtn addTarget:self
           action:@selector(toCart:) forControlEvents:UIControlEventTouchDown];

In toCart method I need to get row and section by tapped button tag. How can I do it?

See this code

- (void)toCart:(id)sender
{
    CGPoint buttonPosition = [sender convertPoint:CGPointZero toView:self.tableView];
    NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:buttonPosition];
    if (indexPath)
    {
     ...
    }
}

this is still a very nice and clean way to do this. No superview or tag hacking. – brainray Jun 05 '16 at 20:52

Use this simple code if UIButton is subview in cell

- (void)toCart:(id)sender 
{
UIButton *senderButton = (UIButton *)sender;
UITableViewCell *cell=(UITableViewCell*)senderButton.superView;
NSIndexPath *index = [tableView indexPathForCell:cell];
}

Create a custom UITableViewCell subclass and handle the touch in there.

Then define a delegate for your custom table view cell and when you create the cell, assign your table view data source as the delegate.

When the cell handles the touch, send a message to the delegate and then find the index path from the table view.

-(void)customTableViewCellButtonPressed:(CustomTableViewCell *)cell {
    NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
    ...
}

I also like the indexPathForRowAtPoint: methods others have suggested. — kball, Jul 12 '13 at 06:03

try this:

- (void)toCart:(id)sender {
    CGPoint button1 = [sender convertPoint:CGPointZero toView:self.tblName];
    NSIndexPath *index = [self.tableView indexPathForRowAtPoint:button1];

    //use index variable
}

For Swift

    let buttonPosition:CGPoint = sender.convert(CGPoint.zero, to: self.tableViewItems)
    let indexPath = self.tableViewItems.indexPathForRow(at: buttonPosition)
    if (indexPath != nil)
    {
        print(indexPath?.section)
        print(indexPath?.row)
    }
