Answer 1

you can accomplish this by using NSNotificationCenter

in your firstView you can write a code like:

 -(void)viewDidLoad{
 [[NSNotificationCenter defaultCenter] removeObserver:self];
 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(modifyCell:) name:@"modifyCell" object:nil];
 }

   //make sure this is declared in your .h
 -(void)modifyCell:(NSNotification*)notif
  {
    if (notif) {
              //cellindex to modify
    NSString *cellIndex = [[notif userInfo] objectForKey:@"index"];
    [yourDataSource removeObjectAtIndex:[cellIndex intValue]]
    [yourTableView reloadData];
     }
  }

in your secondView:

  -(void)switchChanged
  {
     NSNotificationCenter *ncSubject = [NSNotificationCenter defaultCenter]; 
     NSDictionary* dict = [NSDictionary dictionaryWithObjectsAndKeys:@"indexNum",@"index", nil];
      [ncSubject postNotificationName:@"modifyCell" object:nil userInfo:dict];
      [ncSubject removeObserver:self];
  }
