UICollectionView and cell separators? Is this something to be handled by supplementary views? Decoration views? Within the cell itself?

Question

I'm a little new to UICollectionView, and I'm trying to build a vertical list of items with only one column/only one item per row.

Between each UICollectionViewCell I want to have a divider line, similar to UITableView's separator. (No I can't use UITableView for this purpose due to other reasons.)

How should I be accomplishing this? Simply adding a 1px high UIView to each cell? Use a "supplementary view"? Use a "decoration view"? I'm lost and no tutorials seem to indicate what would be best here.

It seems ridiculous to have to reimplement the full UICollectionViewLayout to have some lines, but throwing the line in each cell seems sloppy. What should I be doing?

Answer 1

I think the problem is with connection flow layout

You can write this code in viewDidLoad

UICollectionViewFlowLayout *flowLayout = [[UICollectionViewFlowLayout alloc] init];
[flowLayout setScrollDirection:UICollectionViewScrollDirectionHorizontal];
//You can provide vertical


[flowLayout setMinimumInteritemSpacing:0.0f];
[flowLayout setMinimumLineSpacing:0.0f];
[self.pictureCollectionView setPagingEnabled:YES];
[self.pictureCollectionView setCollectionViewLayout:flowLayout];
[self.pictureCollectionView setBackgroundColor:[UIColor whiteColor]];

Set this as your flow layout. I once made a slide show with only one row and a column and added this as a flow layout.

Later use UIEdgeInsets or draw a border of collection cell
