Question

This may be a simple question for you experts but I can’t figure out the correct solution.

In my app I created a a table view to list a no of items.

In the first row of the cell there a switch (ON/OFF).

So my client need to hide the bottom cells(other than zeroth cell) when switch is OFF and show all the cells when switch is ON.

I created the switch through code.

Can anyone please help me with how to do this?

Thanks in advance.

numberOfRows dataSource method – make it return 1 and reloadTableView

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
  /// ....
            self.switchView = [[[UISwitch alloc] initWithFrame:CGRectZero]autorelease];
            cell.accessoryView = self.switchView;
            [self.switchView setOn:NO animated:NO];
            [self.switchView addTarget:self action:@selector(switchChanged:) forControlEvents:UIControlEventValueChanged];

//....

}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
   if [self.switchView.on]
       return 1;
   else 
   {
      // normal code return
   }
}

- (void) switchChanged:(id)sender {
     [self.tableView reloadData];
}
