How to know the UITableview row number

Question

I have a UITableViewCell with UISwitch as accessoryview of each cell. When I change the value of the switch in a cell, how can I know in which row the switch is? I need the row number in the switch value changed event.

Tags, subclasses, or view hierarchy navigation are too much work!. Do this in your action method:

CGPoint hitPoint = [sender convertPoint:CGPointZero toView:self.tableView];  NSIndexPath *hitIndex = [self.tableView indexPathForRowAtPoint:hitPoint]; 

Works with any type of view, multi section tables, whatever you can throw at it - as long as the origin of your sender is within the cell's frame (thanks rob!), which will usually be the case.

And here it is in a UITableView Swift extension:

extension UITableView {     func indexPath(for view: UIView) -> IndexPath? {         let location = view.convert(CGPoint.zero, to: self)         return self.indexPathForRow(at: location)     } }
