Why do we set delegate to nil at dealloc if the object is going to be destroyed anyway?

Question

-(void) scrollViewDidScroll:(UIScrollView *)scrollView
{
    PO(NSStringFromCGPoint(self.tableView.contentOffset));
    PO(NSStringFromUIEdgeInsets(self.tableView.conten

Actually this is not required. We are doing this to avoid forming retain cycle. We should not create a delegate with strong reference. If you accidentally created a delegate with strong reference then both parent and child will not get released. In that case dealloc itself will not get called. So it s not necessary.
