Question

I’, have a UITableView with UISwitch in some cells.

I want to capture events, but it crashes when I try to add the indexPath.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

 //Create cell with all data

    UISwitch *switchview = [[UISwitch alloc] initWithFrame:CGRectZero];
    cell.accessoryView = switchview;
    [switchview addTarget:self action:@selector(updateSwitchAtIndexPath) forControlEvents:UIControlEventTouchUpInside];
}


- (void)updateSwitchAtIndexPath:(NSIndexPath *)indexPath {

   UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
   UISwitch *switchView = (UISwitch *)cell.accessoryView;

   if ([switchView isOn]) {
       NSLog(@"ON");
   } else {
       NSLog(@"OFF");
   }

}

It crashes, I think because I’m not adding the indexPath parameter, but I can’t get how to set it.

Thanks!

UPDATE

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

 //Create cell with all data

    UISwitch *switchview = [[UISwitch alloc] initWithFrame:CGRectZero];
    cell.accessoryView = switchview;
    [switchview addTarget:self action:@selector(updateSwitchAtIndexPath:) forControlEvents:UIControlEventTouchUpInside];
}


- (void)updateSwitchAtIndexPath:(UISwitch *)switchview {
   if ([switchView isOn]) {
       NSLog(@"ON");
   } else {
       NSLog(@"OFF");
   }

}
