Each time the UISwitch is flipped, you need to add a new row to your section that has ImageView.

To add more rows and to hide a section, all you need to do is to call reloadData on your tableView. Once you call this reloadData, 2 of your following functions will be called again. 

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
- (UITableViewCell *)tableView:(UITableView *)tableView  cellForRowAtIndexPath:(NSIndexPath *)indexPath

All you have to do now, is that once your switch if flipped, save a boolean and return different values in your functions.

For example. 

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
if(switchState.on)
{
 return 2; // now you are hiding your last section. 
}
else
{
return 3; // now you are showing all 3 sections when switch is off.
}
}
