Select UITableView's row when clicking on UISwitch

Question

I have a UITableView with UISwitchs on them.

When the switch is toggled I want to run a function. The function just logs If the switch is on or off and the row that the switch has been changed on. The problem that im having is that when I click on the switch it does not log the correct row unless I have clicked on that row before clicking the switch.

I guess my problem is that clicking the switch does not select the row. How can I make it so that it either selects the row or can I add the ID to the switch?

So switch ID "1" is "ON".

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    static NSString *CellIdentifier = @"POICell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];


    //set the cell text to the catName
    cell.textLabel.text = [self.catNames objectAtIndex:[indexPath row]];
    //add switch 
    cell.selectionStyle = UITableViewCellSelectionStyleNone;
    UISwitch *switchView = [[UISwitch alloc] initWithFrame:CGRectZero];
    cell.accessoryView = switchView;
    [switchView setOn:YES animated:NO];

    [switchView addTarget:self action:@selector(switchChanged: ) forControlEvents:UIControlEventValueChanged];
    // Configure the cell...

    return cell;
}

     - (void) switchChanged:(id)sender {
            NSString *StrCatID =[[NSString alloc]init];
            StrCatID = [self.catIDs objectAtIndex:[self.inputTableView indexPathForSelectedRow].row];
            UISwitch* switchControl = sender;
            NSLog( @"The switch for item %@ is %@",StrCatID, switchControl.on ? @"ON" : @"OFF" );
        }

To find the cell that holds the switch

UISwitch *switchInCell = (UISwitch *)sender;
UITableViewCell * cell = (UITableViewCell*) swithInCell.superview;

To find the indexpath of that cell

NSIndexPath * indexpath = [myTableView indexPathForCell:cell]

In your case

 - (void) switchChanged:(id)sender {

         UISwitch *switchInCell = (UISwitch *)sender;
         UITableViewCell * cell = (UITableViewCell*) swithInCell.superview;
         NSIndexPath * indexpath = [myTableView indexPathForCell:cell]
         NSString *strCatID =[[NSString alloc]init];
         strCatID = [self.catIDs objectAtIndex:indexpath];
         NSLog( @"The switch for item %@ is %@",StrCatID, switchInCell.on ? @"ON" : @"OFF" );
        }

You should set the IndexPath.row as a Tag to each Switch in cellForRowAtIndexPath Method

 switchView.tag= indexPath.row;

And when switch value change .you'll get the Row number

- (void) switchChanged:(UISwitch *)sender {
  int rowIndex =[sender tag];
  //rowIndex you may use it further as you wanted.   

}

You can retrieve the NSIndexPath for the UISwitch that was changed in the tableview. This is the same idea for any control as already answered in this post : Detecting which UIButton was pressed in a UITableView

- (void) switchChanged:(id)sender 
{
    CGPoint switchPositionPoint = [sender convertPoint:CGPointZero toView:[self tableView]];
    NSIndexPath *indexPath = [[self tableView] indexPathForRowAtPoint:switchPositionPoint];
}

This will work for iOS7, previously I used [sender superview] but that now returns a UITableViewCellContentView inside of a UITableViewCellScrollView.
