14. ASTableNode replaces UITableView's required method. Texture does not use cell reuse does not calculate height of cell automatically or LayoutSpec in Cell node blocks be thread-safe func tableNode(_ tableNode: ASTableNode, nodeBlockForRowAt indexPath: IndexPath) let cellNodeBlock = { () -> ASCellNode in return SampleCellNode(item: item) } return cellNodeBlock }
23. Layout: sample code override func layoutSpecThatFits(_ constrainedSize: ASSizeRange) -> ASLayoutSpec let stackSpec = ASStackLayoutSpec( direction: .horizontal, spacing: 11.0, justifyContent: .start, alignItems: .center, children: [self.imageNode, self.titleNode] ) let insetSpec = ASInsetLayoutSpec( insets: UIEdgeInsets(top: 8, left: 8, bottom: 8, right: 8), child: stackSpec ) print(insetSpec.asciiArtString()) return insetSpec }
24. Layout Debugging ASLayoutSpec has asciiArtString() property. ------------------------------------------ASInsetLayoutSpec--------------------------- | ---------------------------------------ASStackLayoutSpec--------------------------- | | --------------------------ASStackLayoutSpec----------------- | | | ASTextNode | | | ASLayoutSpec | | ASNetworkImageNode | -----------------------ASStackLayoutSpec----------------- | | | | ASNetworkImageNode ASLayoutSpec ASImageNode ASTextN | | | --------------------------------------------------------- | | ------------------------------------------------------------ | ----------------------------------------------------------------------------------- --------------------------------------------------------------------------------------
28. In nitely scrolling class ViewController: ASViewController<ASTableNode> { fileprivate func loadPageWithContext(context: ASBatchContext) { // insert logic self.tableNode.reloadData() context.completeBatchFetching(true) } } extension ViewController: ASTableDataSource, ASTableDelegate { func tableNode(_ tableNode: ASTableNode, willBeginBatchFetchWith context: ASBatchC context.beginBatchFetching() loadPageWithContext(context: context) } }
29. In nitely scrolling (with RxSwift) class ViewController: ASViewController<ASTableNode> { fileprivate func loadPageWithContext(context: ASBatchContext) { fetch().subscribe(onNext: { (elements) in self.addRowsIntoTableNode(newElementsCount: elements.count) context.completeBatchFetching(true) }).disposed(by: disposeBag) } func addRowsIntoTableNode(newElementsCount newElements: Int) { let indexRange = (elements.count - newElements..<elements.count) let indexPaths = indexRange.map { IndexPath(row: $0, section: 0) } node.insertRows(at: indexPaths, with: .none) } } extension ViewController: ASTableDataSource, ASTableDelegate { func tableNode(_ tableNode: ASTableNode, willBeginBatchFetchWith context: ASBatchC
