BWListKit 是基于UITableView/UICollectionView封装了各自的delegate、datasource协议方法，提供了基于数据驱动的列表构建方式，采用Adapter适配器大大减少了代码量，提高了开发效率，提高了封装性和统一性。
class BWListAdapter: NSObject {
weak var tableView: UITableView?
weak var collectionView: UICollectionView?
weak var scrollDelegate: BWListScrollDelegate?
var data: BWListData? = nil {
didSet{
_registerTableView()
_registerCollectionView()
tableView?.reloadData()
collectionView?.reloadData()
}
}
Adapter类中存储了外部用户的tableView和collectionView，动态进行了cell、header、footer的注册，及数据加载
convenience init(tableView: UITableView? = nil,
collectionView: UICollectionView? = nil,
scrollDelegate: BWListScrollDelegate? = nil) {
self.init()
if tableView == nil && collectionView == nil {
fatalError("必须提供一个UITableView或UICollectionView！")
}
else if tableView != nil && collectionView != nil{
fatalError("只能绑定一个UITableView或UICollectionView！")
}
tableView?.dataSource = self
tableView?.delegate = self
collectionView?.dataSource = self
collectionView?.delegate = self
self.tableView = tableView
self.collectionView = collectionView
self.scrollDelegate = scrollDelegate
}外部调用方法极其简单，传入一个
listView和scrollDelegate即可完成初始化
该extension中主要实现了UICollection/TableView的代理方法，进行了cell、header、footer的设置，及点击等action方法的实现和设置
- CollectionView
extension BWListAdapter: UICollectionViewDataSource {
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let sections = data!.sections!
let item = sections[indexPath.section].items![indexPath.item]
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: item.reuseId, for: indexPath)
if let proxy = cell as? BWListItemView {
proxy.bwListItemViewConfigure(item.data, indexPath: indexPath)
}
return cell
}
}- TableView
extension BWListAdapter: UITableViewDataSource {
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let sections = data!.sections!
let item = sections[indexPath.section].items![indexPath.row]
let cell = tableView.dequeueReusableCell(withIdentifier: item.reuseId) ?? tableView.dequeueReusableCell(withIdentifier: item.reuseId, for: indexPath)
if let proxy = cell as? BWListItemView {
proxy.bwListItemViewConfigure(item.data, indexPath: indexPath)
}
return cell
}
}- ScrollView
该extension中实现了列表的滚动代理UIScrollViewDelegate方法
extension BWListAdapter: UIScrollViewDelegate{
func scrollViewDidScroll(_ scrollView: UIScrollView) {
scrollDelegate?.bwListScrollViewDidScroll(scrollView)
}
func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
scrollDelegate?.bwListScrollViewDidEndDecelerating(scrollView)
}
}该类为BWListView的数据模型类，其中包含了
BWListRegister、BWListSection、BWListItem、BWListSectionLayout、BWListHeaderFooter、BWListItemAction
- BWListRegister //xib、class注册模型
- BWListSection //分组模型
- BWListSectionLayout //分组布局模型
- BWListHeaderFooter //分组头部模型
- BWListItem //cell模型
- BWListItemAction //cell的action（如点击等）模型
@IBOutlet weak var tableView: UITableView!
private lazy var listAdapter = BWListAdapter(tableView: tableView)
override func viewDidLoad() {
super.viewDidLoad()
reloadData()
}
private func reloadData() {
let doingCellRID = STRefundDetailDoingCell.RID
let successCellRID = STRefundDetailSuccessCell.RID
let refuseCellRID = STRefundDetailRefuseCell.RID
let closeCellRID = STRefundDetailCloseCell.RID
let historyCellRID = STRefundDetailHistoryCell.RID
let goodsDoingCellRID = STRefundDetailGoodsDoingCell.RID
let goodsExpressCellRID = STRefundDetailGoodsExpressCell.RID
let goodsDeliverCellRID = STRefundDetailGoodsDeliverCell.RID
typealias Data = RefundDetailCellData
let autoHeight = UITableView.automaticDimension
listAdapter.data = .init(registers: [

}- Cell用法
需实现BWListItemView协议
class STRefundDetailDoingCell: UITableViewCell, BWListItemView {
@IBOutlet var dots: [UIView]!
@IBOutlet var lines: [UIView]!
@IBOutlet var labels: [UILabel]!
// Data为用户自定义数据结构
override func bwListItemViewConfigure(_ data: Any?, indexPath: IndexPath) {
guard let data = data as? Data,
data.process >= 0 else {
return
}
for (i,v) in dots.enumerated() {
let isSelected = i <= data.process
v.backgroundColor = isSelected ? STColor.themColorRead : STColor.fontColorE
}
for (i,v) in lines.enumerated() {
let isSelected = i <= (data.process-1)
v.backgroundColor = isSelected ? STColor.themColorRead : STColor.fontColorE
}
}
