How to make two custom tableviews that works like a 2 rows uipickerview

I created a uiscrollview and add a uitableview as subview. I use this class to create two scrollivew each has added a tableview inside it. I want these 2 tableview works like uipickerview which has 2 rows in it. When I click a uitableviewcell on the left, the other tableview should reload it's data to match the selection. Just like a uipickerview, when click a item in row 0, row 1 updates it's data. I want to implement this functionality in tableview, the only difference is that i click the cell in tableview, not scroll item like uipickerview.


You need to keep reference of two tableViews, two seperate dataSource array. And when the mainTableView is selected, form the dataSource of the second tableView and reload it.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
    if (tableView.tag == 1) //Main TableView
         //Form the dataSource of the second tableView
         //You need to have a logic to form this array  
         //from the selected indexPath of main tableView
         self.secondDataSourceArray = ...
         [self.secondTableView reloadData];
