How do I achieve spacing between pages in a UICollectionView?

Question

UICollection has paging just like a UIPageViewController. With the latter, you have UIPageViewControllerOptionInterPageSpacingKey to easily set the spacing. How is this best achieved with a UICollectionView?

Never used what you are asking, but as a long shot does this help http://stackoverflow.com/questions/21071043/decrease-space-between-uicollectionviewcells/21074972#21074972 — DogCoffee, Jul 09 '14 at 07:53

You can probably accomplish explicitly with UICollectionViewLayoutAttributes, but my approach (that works for collection views and my own subview-containing scroll views) is to tile the cells with no spacing (which makes the layout math simple), but make the cells transparent.

Then within each cell create a more opaque content view whose frame is an insetRect on the cell's bounds.

You can use the collectionView:layout:insetForSectionAtIndex: method for your UICollectionView. You need to add this code...

- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section{
    return UIEdgeInsetsMake(top, left, bottom, right);
}
