Classes

The following classes are available globally.

  • CarrouselCollectionView which multiplies source to make feel it is infinitely scrolls

    You can trach centered indexPath and sourceIndexPath by setting VHCarrouselCollectionView.carrouselDelegate

    – Configuration:

    You should call following functions in releated delegates

    1) VHCarrouselCollectionView.scrollViewWillBeginDragging()

    2) VHCarrouselCollectionView.scrollViewWillEndDragging(...)

    3) VHCarrouselCollectionView.scrollViewDidEndScrollingAnimation()

    – Usage:

    Attention

    You should call

    • scrollViewWillBeginDragging() in UICollectionViewDelegate.scrollViewWillBeginDragging(...)
    • scrollViewWillEndDragging(...) in UICollectionViewDelegate.scrollViewWillEndDragging(...)
    • scrollViewDidEndScrollingAnimation() in UICollectionViewDelegate.scrollViewDidEndScrollingAnimation(...)

    While using indexPath to get your related item from your source list, you should normalize it because this collectionView multiplies the indexPath.

    Ex:

    let source: [UIColor] = [.purple, .green]
func collectionView(
    _ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath
) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! LocalCVC
    let sourceIndex = indexPath.vhCarrouselSourceIndexPath(for: collectionView).item
    cell.backgroundColor = source[sourceIndex]
    return cell
}

    Attention

    This collectionView has some limitations:

    • Only Horizontal direction supported
    • Only one section supported
    • Layout should be UICollectionViewFlowLayout
    • All cell sizes should be same
    • Supplementary elements are not supported (Ex: Header, Footer)
