extension HomeScreen: UITableViewDataSource, UITableViewDelegate, UITableViewDataSourcePrefetching {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
10
}
func tableView(_ tableView: UITableView, prefetchRowsAt indexPaths: [IndexPath]) {
print(indexPaths)
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "StoryCell") as? StoryTableViewCell
cell?.remixDelegate = self
cell?.reloadAllData(index: indexPath.row)
return cell!
}
func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
print("TableView Will display",indexPath.row)
guard cell is StoryTableViewCell else { return }
}
func tableView(_ tableView: UITableView, didEndDisplaying cell: UITableViewCell, forRowAt indexPath: IndexPath) {
guard let tableViewCell = cell as? StoryTableViewCell else { return }
tableViewCell.pauseAllCell()
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return storyTableView.frame.height
}
}
custom class of table view in which collection view methods written

here is my custom class of table view
// MARK: - UICollection View Delegates

print("CellForRowAt",indexPath.row)
let cell: RemixCollectionViewCell = (collectionView.dequeueReusableCell(withReuseIdentifier: "RemixCell", for: indexPath) as? RemixCollectionViewCell)!
cell.configure(url: urlArray[indexPath.row])
cell.remixButton.tag = indexPath.row
cell.remixButton.addTarget(self,action:#selector(onRemix(sender:)), for: .touchUpInside)
return cell
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
print("Collection view at row (collectionView.tag) selected index path (indexPath)")
}
func collectionView(_ collectionView: UICollectionView, willDisplay cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {
print("willDisplay", indexPath.row)
if let cell = cell as? RemixCollectionViewCell {
oldAndNewIndices.1 = indexPath.row
currentIndex = indexPath.row
cell.pause()
}
}
func collectionView(_ collectionView: UICollectionView, didEndDisplaying cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {
print("didEndDisplaying", indexPath.row)
if let cell = cell as? RemixCollectionViewCell {
cell.pause()
}
}
func collectionView(_ collectionView: UICollectionView, prefetchItemsAt indexPaths: [IndexPath]) {
print("prefetchItemsAt", indexPaths)
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
let size = CGSize(width: collectionView.layer.frame.width, height: collectionView.layer.frame.height)
return size
}
}
// MARK: - ScrollView Delegates
extension StoryTableViewCell: UIScrollViewDelegate {
func scrollViewDidEndDragging(_ scrollView: UIScrollView, willDecelerate decelerate: Bool) {
let cell = self.remixCollectionView.cellForItem(at:
IndexPath(row: self.currentIndex, section: 0)) as?
RemixCollectionViewCell
cell?.replay()
}
}
