Question

I have a tableview with custom UITableViewCells, each row in the table has a UILabel, UISwitch and detail disclosure indicator.

I’m looking for the best method of capturing the UIControlEventChanged for the switch but I also need the NSIndexPath of the switch that changed to update Core Data.

I don’t want the UISwitch as an accessory type either.

I’ve been googling this for hours and the solution that keeps popping up is to use

[switch addTarget:self action:@selector(switchTapped:) forControlEvents:UIControlEventChanged];

then in the switchTapped: method use the following to get the NSIndexPath

NSIndexPath *indexPath = [self.tableView indexPathForCell:(UITableViewCell *)[[sender superview] superview]];

Is there a better way of doing this? I already have UITableViewCell subclassed, can I put a method in this class to return the NSIndexPath for a given switch?

Thanks in advance for any help

I’ll take another opportunity to link to my answer here – tags and view hierarchy walking are clunky, error prone and unnecessary, and I see them recommended all over the place in SO answers. You can find the index path of any control using its frame and the table view’s indexPathForRowAtPoint: method.
