Answer 1

you can add a property in the CustomTableViewCell like superIndexPath. And set the property at - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath like
cell = (CustomTableViewCell *)[tableView dequeueReusableCellWithIdentifier:#"CustomTableViewCell"];
if (cell==nil)
{
cell = [[CustomTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"CustomTableViewCell"];
}
cell.superIndexPath = indexPath;
return cell;
and When you try to get the tableView indexPath in the method - (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath by using self.superIndexPath.

Answer 2

You can use superView property of the collectionViewCell inside didSelectItemAtIndex and cast it as your CustomTableViewCell. Try this code inside didSelectItemAtIndex
if let tableViewcell = collectionViewCell.superview?.superview as? CustomTableViewCell {
let indexPath = customTableView.indexPath(for: tableViewcell)
}
