changing a picker to table view OR having multiple table views on the same view

My iPad app was rejected due to my use of a picker. The picker was used to control a table view. In my view, a picker was displaying a series of items and when开发者_如何学C one of those items was selected, it used that selection to populate a table with data. (hopefully that makes sense). Now I need to do this without the picker so I need to have the data that was in the picker be represented in a table view.

My question, is how do I have multiple tableViews in the same view?

is it as simple as having separate delegate methods for each tableview like this?

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView1
{

    return [xxx count];

}

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView2
{

    return [yyy count];

}

The names of the delegate methods are fixed. So you can either

1. Use two different delegate instances, or

2. Identify the table within the method, e.g.

   -(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
       if (tableView.tag == 114)
         return [xxx count];
       else
         return [yyy count];
   }
