When you clicked on second cell you are not changing image on first cell.

So make sure that if you clicked on any cell change the image as product-check.png and previous cell image as product-uncheck.png

Do like this When Button is Pressed

-(void)selectitem :(UIButton *)sender{

//Get Index path from Button Tag
  NSIndexPath *indexPath = [NSIndexPath indexPathForRow:sender.tag inSection:0];

// get Cell instance and than do whatever you want with Cell items
CustomCell *cell = *cell = [self.collectionView cellForItemAtIndexPath:indexPath];

if ([cell.Selectitems isSelected]) {
    [cell.Selectitems setSelected: NO];
    cell.check = YES;
     [cell.Selectitems setBackgroundImage:[UIImage imageNamed:@"product-uncheck.png"] forState:UIControlStateNormal];
}else{
        [cell.Selectitems setSelected: YES];
        cell.check = YES;
      [cell.Selectitems setBackgroundImage:[UIImage imageNamed:@"product-check.png"] forState:UIControlStateNormal];
}
}

i hope this will solve your problem .
