UICollectionView : two columns - ios

Question

I have a collectionview that will be a menu with two columns, without spacing: so each cell with width 160. And I need a line separating each cell.
Each cell contains an imageview and a label.
I'm trying to add a line separator between the cells like this: How to add views between UICollectionViewCells in a UICollectionView?
But the result is:
Code:
- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section {
return UIEdgeInsetsMake(0, 0, 0, 0);
}
- (NSInteger)collectionView:(UICollectionView *)view numberOfItemsInSection:(NSInteger)section {
return 2;
}
// 2
- (NSInteger)numberOfSectionsInCollectionView: (UICollectionView *)collectionView {
return [options count];
}
// 3
- (UICollectionViewCell *)collectionView:(UICollectionView *)cv cellForItemAtIndexPath:(NSIndexPath *)indexPath {
static NSString *identifier = #"MenuOptionCell";
UICollectionViewCell *cell = [self.menu dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];
UIImageView *img = (UIImageView*) [cell viewWithTag:100];
UILabel *lbl = (UILabel*) [cell viewWithTag:90];
UIView *seperatorView = [[UIView alloc] initWithFrame:CGRectMake(cell.frame.origin.x+10, cell.frame.origin.y+cell.frame.size.height, cell.frame.size.width-10, 1)];
seperatorView.backgroundColor = [UIColor whiteColor];
[self.menu addSubview:seperatorView];
[self.menu bringSubviewToFront:seperatorView];
UIView *seperatorView2 = [[UIView alloc] initWithFrame:CGRectMake(cell.frame.origin.x+cell.frame.size.width-10, cell.frame.origin.y, 1, cell.frame.size.height)];
seperatorView.backgroundColor = [UIColor whiteColor];
[self.menu addSubview:seperatorView2];
[self.menu bringSubviewToFront:seperatorView2];
lbl.text = #"TEST";
img.image = [UIImage imageNamed:#"test.png"];
return cell;
}
