However, with the "traditional" UITableViewCell, it does "climb" the hierarchy, which may well be for another reason. It still however leaves me puzzled as to why I cannot implement Swipe to delete. (the 2 usual suspects), ie -(BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath; -(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath are implemented. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
